Oppo R17 Neo Supports ANT+?

Does my new Oppo R17 Neo support ANT+? I looked at its specifications, but there was no mention of ANT+. So it was super unlikely, but I tested it anyway. Surprisingly, it seems it does. I have not tested if it actually works with an ANT+ device yet, though.

I installed ANT Radio Service and ANT+ Plugins Service, and ran ANTtester to see if my Oppo R17 Neo supported ANT+.

Figure 1 shows its initial output, and it surprised me. Wait, it supports ANT+ hardware-wise? So I tapped on the red padlock icon shown next to “ANT Radio Service” (Figure 2) and a window popped up which told me I needed to give proper permission to ANT Radio Service (Figure 3).

Tapping on “OK” brought up the app settings window for ANT Radio Service (Figure 4). Tapping on “Permissions” opened up the app permissions page (Figure 5). Tapping on “Additional permissions” brought up yet another window (Figure 6). There I could finally turn on “use ANT hardware” (Figure 7). After this, the output of ANTtester changed, and it showed my Oppo R17 Neo was ready to work with ANT+ devices — supposedly (Figure 8).

ANT and its extended version ANT+ is a wireless communication protocols used in sensors. They may be gradually be superseded by the incompatible Bluetooth Low Energy (BLE), but they were widely used in fitness-related sensors. I happened to own Sony Xperia’s and Samsung Galaxy’s which supported ANT+, so I have an ANT+-based heart rate monitor. I have written the following articles for this reason.

Public Wifi Services in Japan

Japan was once notorious in the past among foreign visitors for its universal unavailability of free wifi services. Public wifi services were rare, and even when there was one, it was for paid members only.

For a comprehensive list of the articles I have written for foreign people living or traveling in Japan, see this article.

We recognized that is one major annoyance for visitors from overseas, which needed to be remedied so we could entice more visitors. We have come a long way in improving the situation. Free public wifi is still not everywhere; it is not like you can just walk for a few blocks and get free wifi outside a coffee shop, and it probably never will be, given our safety-oriented mindset. However, many kinds of organizations — convenient store chains, restaurant chains, municipalities, etc. — have implemented their own versions of public wifi systems. The problem is that they almost always do not allow you to simply connect to their hotspots; they require that you register with their services in advance and also that you input your login credentials in the browser when you try to connect. That’s a lot of work!

Enter TownWiFi. They provide an Android app and ‎an iOS app. The app first asks for a little bit of your personal information, with which they automatically register you with dozens of those free public wifi providers. The app shows you a map of nearby hotspots, and it automatically logs you in when you are close enough to one. What a life saver!

You can configure it to use VPN for added security when you connect to a hotspot by TownWifi. You could call it a limited form of VPN in that connections made through HTTPS are excluded and videos and/or audio streaming is excluded as well. But that is hardly an issue because HTTPS itself is secure enough and not much damage can be done by listening in or tampering with video/audio streaming. It is impressive that they offer this VPN feature for free for unlimited use. This feature is embedded in the Android app, but iOS users need to use ‎a separate app called WiFi Protect. I could not find any info written in English on how to use these two apps together but you can find instructions in Japanese in this article.

TownWifi cannot take care of the initial registration required for the wifi services for Shinkansen (Bullet Train) cars and stations. But once that has been taken care of, TownWifi should automatically connect you to those services.

Incidentally, they claim to provide info on hotspots in “USA, Japan, Korea, Taiwan, Hong Kong, (and) Macau,” although when the app shows it has support for other areas such as Europe as well. For global use, though, you might want to check out other options.

Now, the bar is definitely high for this one, but there is a paid service
called Gigazo
. They offer an Android app and ‎an iOS app. Their standard plan costs about 500 yen a month (~$5 USD/mo), but your first two months are free. That might cover your whole stay in Japan. Gigazo also provides VPN for connections through their hotspots, so that is good. One ID, namely one contract, allows you to use Gigazo on five devices simultaneously, which I find very generous.

All this info is available only in Japanese and their English page shows completely different services. This might mean that they do not intend Gigazo, or its two-months-free deal in particular, for foreign visitors. I do not know.

By the way, I referenced the following article in writing this article.

In addition to the two services/apps above, the article also lists Japan Connected-Free Wi-Fi service. It is similar to TownWifi in its goals and scope, and has similar features. The site is offered by Japan Tourism Agency, but it appears it’s not like they run their own network of free public wifi services — they just list free public wifi services offered by various municipalities, which TownWifi does too, only more exhaustively.

The Japan Connected-free Wi-Fi app has a few notable advantages over TownWifi. One is that it supports as many as 16 languages for its UI language. Another is that it can allow you to download maps of hotspots for your use when you are offline. Personally I am shying away from it because its Android version has a low rating of 2.6 out of 5.0. Its reviewers complain that even though the app is supposed to let you auto log on to hotspots, but this automatic authentication process often fails. Plus it does not offer any protection by VPN like TownWifi does.

Wifi Availability in JR Tokai Shinkansen Trains and Stations

Free wifi services are available for those who travel using JR Tokai (or “JR Central Japan Railway Company”). In the network of Shinkansen train services in Japan, JR Tokai covers the segment between Tokyo and Shin-Osaka. They are available in some of its Shinkansen (Bullet Train) trains and at all of the stations.

For a comprehensive list of the articles I have written for foreign people living or traveling in Japan, see this article.

This page gives you instructions on how you can take advantage of them. You need to note the following:

Both the in-car wifi service and the at-station wifi service require your initial registration. However, once that has been taken care of, such auto-wifi-login-app like TownWiFi should automatically get you connected again whenever you are cut off after the predetermined time (See “Free Public Wifi Services in Japan” for more on TownWifi).

This page gives detailed instructions on how to use the in-car wifi service.

By the way, this is probably of little importance to visitors from overseas, but they put up yet another sign for a different kind of wifi availability. This one is for commercial public wifi services. I subscribe to one of those services (Wi2), but sadly, I do not have access to the in-car wifi service.

 

Overseas Public Free Wifi Service Finder Apps

I’m looking for an overseas public free wifi service finder app, particularly with its use in Europe in mind.

These apps often encourage you to share the wifi access credentials to your own routers, which they say will be stored securely in the cloud. This access-sharing scheme is in principle similar to what Fon used to do. The difference is that Fon never asked for your personal wifi acccess credentials; instead, they provided dedicated routers, which had a pre-baked guest account, and enforced restrictions on the guests’ use. I think sharing your wifi passwords with others is a whole lot more dangerous, and there has been a major leakage ( “Security researcher discovers hotspot finder app with leaks” ).

Thankfully, sharing your wifi access credentials is usually not a must with recent app — otherwise I would not even consider using them. Another feature of recent apps I liked was the ability to download hotspot-location maps in advance, so you can try to find a hotspot near you even when you do not have Internet access.

With those in mind, I looked at the following:

I checked their maps of a randomly selected place in Italy, and the results were surprisingly different — Wiman showed far more hotspots (see screenshots). It may have something to do with the fact that it is developed by those in Italy. Looks like Wiman is the winner. Neither Wiman nor Instabridge allowed me to download these specific maps, though.

Neither Wiman not Instabridge offers additional security by VPN. This is in stark contrast with TownWiFi, which is mostly for the Japanese audience (See “Free Public Wifi Services in Japan” for more on TownWifi).

I tried WiFi Map too, but I got fed up with the obnoxious amount of ads they threw in there. Plus you need to be a paid member to able to download maps. Supposedly provide a VPN service too (probably just for paid members), so it could potentially be a one-stop solution, though.

I read the following articles for reference:

 

イタリアのコンセント事情

Travel Adaptor for Italy | Electrical Safety First” によると

Italy operates on a 230V supply voltage and 50Hz.

230Vは日本の100Vに比べ高電圧であるが,我々が日常生活で使う電子機器も意外とこの高電圧に対応している。スマホ等デバイスの充電に欠かせないUSB AC充電アダプタも240Vにまで対応している(写真)し,ノートPCのACアダプタも同様。周波数も問題なし。

ただ,プラグの形状が異なることには対処しなくてはならない。 “Italy: power plug adapter needed? | POWER PLUGS AND SOCKETS OF THE WORLD” によれば,コンセントの形状としてはFタイプとLタイプがあるが,Cタイプのプラグであればどちらにも対応できる,とある。なので,日本のプラグからCタイプのプラグに物理的に変換するだけの単純なアダプタを用意すればよい。上で述べたような230Vに対応する機器を使う限り,変圧は不要。

そのような製品は多数販売されており,アマゾンで”EU 変換プラグ”で検索すると多数ヒットする。Cタイプはヨーロッパで広く使われているので,”EU”というキーワードになる。2枚目の写真にあるような単純な変換アダプタで用は達成できるが,いろいろ付加機能つきのものもあり,USB充電ポートがあったり,複数の日本のプラグを差し込めるようになっていたり(つまりミニ・テーブルタップとして機能する)する。

ただ, “IEC – World Plugs: Plug Type C” によると

Type C plugs are generally limited for use in appliances that require 2.5 amps or less.

というのがちょっと心配か…が実際はコンセントの側で対応していて(コンセント側はCタイプに限らずFタイプやLタイプの可能性がある),プラグも対応していれば問題ない?

Italian Electricity and Travel Adapters | Martha’s Italy” では,旅行者は “Schuko” というあだなのあるFタイプを避けるよう勧めている。本来電子レンジ等の高出力機器用の太いプロングを持ったアダプタが旅行者向けに売られている。実際イタリアの普通の家では台所などにそういったプラグに対応したコンセントがある。しかしホテルではそういった機器の使用は想定されてないため,そこにあるコンセントでは,仮にFタイプのものであっても,旅行者向けのものであればプロングが太すぎて挿入できず使えない。この作者のお勧めは無難にはCタイプ,(グラウンド用プロングを持つ3プロングのプラグが存在するアメリカ人向けに書かれた記事なので)グラウンドが必要ならLタイプ。

Cタイプで,2コンセントを持つものが140円ほど3コンセントを持つものだと600円強。Lタイプだと,2コンセント持つのが200円ほど3つ持つものが700円ほど

Cタイプが使われている国は包括的リストがあるが,そこに韓国も含まれている。したがって過去に韓国への渡航経験のある方の場合,そのとき既にCタイプへの変換アダプタを入手されてる可能性がある。

スマホ用モバイルバッテリを選ぶのに考慮すべきいくつかの点

友人のために書いた文章をせっかくなので保存。

スマホ用モバイルバッテリを選ぶのにポイントは何点かある。

  1. ちゃんとしたメーカーのものを選ぶ。バッテリ容量はmAH(ミリアンペアアワー)という単位で表記してあることが多い。大きい数字であればあるほど大容量…なんだけど,この数字があてにならない。特に中華製品は,言ったもん勝ち,よろしく適当な数字を出してくるから怖い。「大容量なのにすごく安い!」と思うような製品は,容量を偽ってる可能性を疑ったほうがよい。
  2. 急速充電に対応していれば(最近のいい端末は大概対応している),どういった方式の急速充電が可能かを調べ,それに対応しているバッテリを選ぶのが望ましい。でないとせっかくの性能が発揮できない。
  3. 容量が大きければ大きいほど当然重くなる。一般に容量は大きいほどよいが,重くなりすぎて持ち運ばなくなってしまったら意味がない。なので,どの程度の重さまで自分は許容できるのか自分で判断する必要がある。
  4. モバイルバッテリ自身の充電ポートは以前はmicro USBのものが多かった。が,最近のスマホはtype-Cを採用しているものが多い。多くの人がmicro USBオス端子を持つ充電ケーブルを既に持っているだろうが,今後必要とするケーブルの種類を減らしていきたいと積極的に考えるのなら,type-Cの充電ポートを持つモバイルバッテリを選ぶとよい。

1.の「ちゃんとしたメーカー」の例としてはAnkerがある。ただ,自分自身はその積極的根拠を知らない。

Choosing the Right Magnetic Charging/Data Cables for My Smart Devices

woman holding pink tulips

An example of a converter adapter and a matching USB cable that attach to each other by magnetism

Charging your smart phone or other electronic devices through a USB cable can be a pain, particularly if that device has a micro USB port and you are old and have deteriorating vision like me. You need to insert the micro USB plug correctly into the receptacle because, unlike the more recent type-C plug, it has a correct side and a wrong side.

Also these charging ports tend to get broken over time because you do this plugging and unplugging over and over again, possibly hundreds of times. Once they are broken, you will no longer have data access to the devices. You might still be able to recharge the devices if they happen to support wireless charging by Qi, but if that is not the case, then you will not able to charge the devices either, which will render them unusable. I have an old Samsung Galaxy S5 smart phone, and its micro USB port is somewhat broken, in that the micro USB plug needs to be inserted at a very specific angle for charging to occur.

Good news! — There is a category of products that can prevent these kinds of tragedies. See the photo above for reference. It is a combination of “converter adapters” that you insert into the charging/data ports of your devices, and matching USB cables. The converter adapters and the dedicated cables attach to each other by magnetism. The ports can be either one of micro USB, type-C, and Lightning, and the converter adapters are “unifying” in the sense the other ends are the same. Once you insert those converter adapters into your devices, the same charging cables can be shared among them.

Such products typically allow you to connect the converter adapter and the cable without you worrying about which side needs to be up. That may not be anything new to type-C users, but to micro USB users like myself, it is quite liberating.

Sikai’s warning on connector compatibility

woman holding pink tulips

PZOZ’s warning on connector compatibility

So I decided to look into this category of products. The problem is that there is no standard, be it de facto or de jure. There are many products in this category and most of the time they are not compatible with one another. Even the same company seems to have already gone over some iterations of product development and generally newer versions are not compatible with older ones. See the images on the right to get a sense of the different kinds of connectors available.

In choosing the right charging cables, I set up the following criteria:

  • Must support micro USB and type-C and optionally Lightning — I do not currently own a device with a Lightning port, but, hey, you never know. Actually I do not own one with a type-C port either, but someone who visits my place often does.
  • Must support both charging and data transmission — I often access my devices from my PC to work on them, so I need data transmission capabilities.
  • Ideally provide adapters that you can use with your existing USB-to-micro USB cables — Some products requires the use of their dedicated cables and they tend to be expensive. I am not inclined to commit to a product series that I do not know very much about. Another reason for this is that those dedicated cables tend to be long (as long as, or longer than 1m or 3’3″), which are unwieldy when you just want to recharge the devices with a portable battery on the go. I have been calling and will continue to call these adapters “converter adapters” in this article.
  • Ideally provide rapid charging even if that means you need to get a dedicated cable for it.
  • Contacts on the plug and the receptacle need to be recessed. — If they are exposed, they are likely to cause a short circuit.

After some hours of agonizing research, I have found the following three candidates:

  • Sikai
  • PZOZ
  • SUNPHG

Their latest iterations look quite similar, at least in the photos they provide. First, I do not know for sure if they are compatible. Even if they are, I have no idea if any of them is the original developer of these products, or if the original developer is elsewhere and all three of them are just copycats. Caution: they do provide different kinds of connectors but here I am talking about one specific kind. It is actually the one shown at the top of the two connector comparison images above.

Sikai seems to be a good candidate except that it does not offer converter adapters for use with “normal” USB cables. They also provide interesting products such as phone docks and Qi/USB-dual-charging adapter, both of which use the same type of magnetic connector. I find the latter particularly interesting. Sikai products in this category seem to be carried by many AliExpress stores.

PZOZ does seem to fit the bill as well. It lines up converter adapters. They seem to have only 5A-capable dedicated cables. Their 3A dedicated cables seem to be incompatible so proper caution is due there — the contacts look different.

A group of products from SUNPHG (I don’t know how you read that) seems to carry similar products. It also provides converter adapters, which look exactly like those from PZOZ and except they are missing logos, and are cheaper than the latter; they are likely knockoffs.

The only gripe I have is this. As to their dedicated cables that support up to 5A, they say this:

Fast Charging: (3 in 1)

For i-product tips, both sides of the cable supports Max 5A fast charging & data sync.

For USB C Android device. Both sides support charging & sync, led light will turn on when power on.

For Micro-USB connector, one side supports fast charging and the other side supports charging and data sync. Simply flipping the side to fit your need.

The product page for their 3A dedicated cables does not list such warning. The seemingly equivalent product from PZOZ does not carry such a warning, but it does not mean the issue is not there.

The devices I own now all have micro USB ports, so that is a bummer. But then again, these devices are not capable of charging by a 5A current, so at this moment, this does not pose a problem to me. The frequent guest to this house has a Softbank Xperia XZ, which supports Quick Charge 3.0, but even for that, a 3A cable should suffice.

I can guess all day, but ultimately I can know the compatibility or effectiveness of these products only after I actually give them a try. I have placed orders for products from all of these three companies, so we will see. Since they are all coming from either mainland China or Hong Kong, it will take more than a month for them to arrive here.

Below I am going to list a few “honorable metions.”

woman holding pink tulips

PZOZ’s warning on compatibility

GARAS’s offerings include a variant where… well, take a look at the pic on the side and you’ll get the idea. This is great because you can “roll” the connector (to use a term from flight) by any degree and it will still attach. It is great it supports data transmission too, not just charging.

But there are a few potential problems: i) because of the round connector, the diameter is likely to be bigger than the thickness of your smart phone, and it might lift it up on the edge if it is placed on a flat surface; and ii) because the contacts are fully exposed on the phone side, it could easily lead to a short circuit.

Possibly for these reasons, it seems they are phasing out those products. The flip side is that they are good bargains now if you do not mind the obvious shortcomings above. The fact they have started selling similar to the products that I have talked about in this article (or perhaps exactly the same with them) seems to prove it.

Wsken’s products (the X1 series, I think) almost meet all the requirements, except that they do not provide converter adapters. These are not compatible with the type I described above, because the former seem to have four contacts and the latter, five.

I have read the following articles too, but they were not really useful.

What to Do in Kobe — from Foreigners’ Perspective

Someone from the US is coming to Japan for sightseeing with her 7-year-old daughter. We have one afternoon-and-evening to spend with them in Kobe. How should we entertain them?

For a comprehensive list of the articles I have written for foreign people living or traveling in Japan, see this article.

Figuring that out is no easy task, because what appeals to foreigners and what does to local folks are often completely different. So I looked through the web pages on the topic that I found through a simple Google search (listed a the end of this article).

First, elimination of the obvious is in order. I am excluding the following from consideration:

  • Oji Zoo and Suma Aquarium — They are going there by themselves.
  • Kobe beef — They are going to have a Kobe beef steak lunch by themselves. Otherwise the restaurant I talked about in “My Favorite Steak Restaurant in Kobe That Serves Kobe Beef… Well, Almost” could have been a candidate.
  • Nankin-Machi (“Nankin” for 南京 or Nanjing), or Kobe’s Chinatown — They are from San Francisco and they have their own big Chinatown there.
  • Kobe Luminarie (Wikipedia), annual illumination event commemorating the Great Hanshin Earthquake that hit Kobe in 1995 — It takes place only in part of every December.
  • Arima Onsen (hotsprings) — Though not entirely undoable, I believe it should be reserved for the occasion when they have more time. Arima is outside Kobe City limits and it takes some driving to get there.
  • Kitano neighborhood, or Kitano Ijin-kan Gai (北野異人館街) — It is an area near Shin-Kobe Shinkansen Station, where early merchants and traders from overseas settled. It has interesting historic European-looking buildings there, but I do not think it will appeal to them much. It is expensive also; they charge several dollars each time you enter a building.
  • Nada Sake breweries — It’d be a fun experience if you love Japanese sake and would like to know how it was traditionally made; I have already brought two separate groups of foreign visitors there. However, I doubt the daughter will appreciate it as much as we sake-loving adults do.

Now, what surprised me most looking through those pages is the fact that they often list the Great Hanshin-Awaji Earthquake Memorial Disaster Reduction and Human Renovation Institution (人と防災未来センター (ウィキペディア)). Boy, was it a mouthful; let’s call it Kobe Earthquake Memorial Museum for short.

In fact, this page lists the museum at the very top. Sure, the ’95 quake was and still is a huge deal for us — after all, we lost more than 6,000 people to the calamity. Yet I did not expect it to draw that much attention from foreign visitors. But then again, our visitors too sit on the Ring of Fire, so they might want to check it out. We actually have been to this museum, and to us, it was a solemn reminder how cruel Mother Nature can be. Even though they are supposed to be all about the Kobe Quake, they also have a theater where you get to experience virtually what it would have been like to be in the midst of the 2011 Tohoku Quake, which caused some nuclear reactors in Fukushima to fail, leading to the infamous nuclear meltdown.

If they are going to this museum, Hyogo Prefectural Museum of Art (Wikipedia) is next door.

There was also another minor surprise in the lists: the Takenaka Carpentry Tools Museum. This page lists it at the very top. In a way, its inclusion is even more surprising than that of the Kobe Earthquake Memorial Museum because the Takenaka Museum is hardly known even among the locals. Personally, I came to know of it only recently, and only by sheer chance; someone I know lives nearby. I have not been in there yet. If you are a wood working enthusiast, this museum might be immensely interesting, but probably not so otherwise. What is good about this museum is its geographical vicinity. They are going to stay at Ana Crowne Plaza Hotel Kobe, which is right next Shin-Kobe Shinkansen Station, and the museum is just a five-minute walk from the hotel. We can easily add it to the plan.

Speaking of geographical vicinity, Kobe Nunobiki Ropeway’s base station is, again, a few minute-walk from the hotel (Wikipedia lists it as “Shin-Kobe Ropeway,” but that’s an old name). It takes you right up to Kobe Nunoboki Herb Gardens (Wikipedia). The cityscape you can view from the gondola and on your way down the mountain is great, but how much you can appreciate the herb gardens depends on your personal tastes. I am no botany afficionado, so I only enjoyed it just like you would a beautiful park. On your way down the mountain, you can elect to visit Nunobiki Falls. When I visited them for the first time as a kid, I was awe struck, but I am not sure how they will appeal to our visitors. These falls may be one of the three “divine” falls in Japan, but, after all, they are just small falls and no Niagra Falls. But don’t just take my word for it; see for yourself.

You could see Kobe Harborland (Wikipedia) as Kobe’s Waterfront, and all the following sites and services are within an easy reach (plus it has ample parking space, which cannot be said of San’nomiya, where parking can be a nightmare):

  • Umie, a gigantic mall
  • Mosaic, a restaurant/shop complex
  • Kobe Port Tower
  • museums
  • cruises of various kinds
  • Meriken Park
  • Manyo-no Yu, hotsprings in a building (Japanese website)

Harborland is an area I like to visit as a local. I like the fact that it faces the ocean and you can get on a cruise if you so choose. I find the atmosphere very relaxing. My concern for our visitors, though, is that since the whole area was developed relatively recently, it is all modern and, as a consequence, it does not give you a feel of traditional Japan.

There are a few places that I found in the list that we can add to the plan relatively easily:

  • traditional “shopping malls” in Motomachi and San’nomiya — unlike large-scale malls typically found in the US in the suburbs, they are just walking-only streets with arching roofs, flanked by many relatively small shops. Not something you get to see in the US (as far as my personal experience there goes), but I have no idea if this is something our visitors will be interested. Personally, I find those small, often esoteric shops under the JR train tracks more interesting, but I do not know about them.
  • Ikuta Shrine — I would definitely enlist this shrine as one of the must-go places if they were visiting Kobe only, but they are visiting Kyoto and Nara too, so… I don’t know.

Finally, given the fact that foreigners often find interesting what we locals tend to simply take for granted and think nothing of, I would like to take them to the following places as well:

Wyze Labs製の監視カメラはOEM提供を受けた製品だった

Wyze Cam v2

WyzeLabs製の監視カメラ“で特にWyze Cam v2について述べた。 “Wyze Cam firmware to Xiaofang? · Issue #243 · samtap/fang-hacks · GitHub” なんかによれば,Wyze社の他のカメラ製品Wyze Cam Panも含めて,どうやら中国の企業からOEM提供を受けたもののようだ。

もともとはHuaLai TechnologyがiSmartAlarmブランド下の製品として出していたiSmartAlarm SpotiCamera KeepがXiaomiブランドにリブランドされ(それぞれ”XiaoFang”と”DaFang”?),それがさらにWyze Cam,Wyze Cam Panになったものと思われる。上記記事によれば,Xiaomi製品とWyzeLabs製品はファームウェアが異なっているだけでなく,異なる部品が使われている可能性があるとのこと(ただし後者について決定的証拠はまだ見かけてないように思う)。また,アプリも同一ではない。

WyzeLabsのカメラ2製品とXiaomiの相当品は値段的にほぼ同等であるが,iSmartAlarmの製品は3倍ほどもするため人の関心は前者にしかない。Xiomiの公式サイトではこれら製品は見つけられなかった。しかも,Xiaomiのスマートホーム製品は”MIJIA”ブランドに含められるようで,それがより話をややこしくしている。さらにXioFang/Wyze Camは一度ハードウェアが刷新されたようで,Wyze Camでは新版を”v2″と明記しているのでわかりやすいが,中華製品を扱うオンラインショップでははっきり区別して表記していないことが多いので注意が必要。新版を”1s”と呼んでいるようにも思えるがはっきりしたことわからない(”Which version of Xiaomi Xiaofang or Xiaofang 1S i have? · Issue #718 · EliasKotlyar/Xiaomi-Dafang-Hacks · GitHub“)。

WyzeCam – A $1999 tiny smart home camera | Product Hunt“には「公式」といっていいであろうコメントがある:

In creating the WyzeCam, we licensed the same industrial design as xiaofang, but we worked directly with the manufacturer to design a new version, the WyzeCam. So while the physical appearance is the same, we created our own Wyze app, firmware and AWS cloud service. We also provide US-Based Tech support to help our customers if they ran into any issues.

同じトピックのトピ主はXiaomiのアプリは非常にできが悪いことを指摘している。

仮にハードウェアが完全に同一だとしても,ファームウェアが異なり,クラウド録画の保存先を含めたインターネット関係の作りが違い,アプリに互換性がないということは,複数製品を同時に使いたいなら,Xiaomi製品ならXiaomi製品,Wyze Labs製品ならWyze Labs製品,だけを使うようにするのが賢明ということ。

AliExpressでXiaofang 1sが2,000円強で購入できるので,米AmazonよりWyze Cam v2を輸入するより安くつく。だが,差額分を支払っても,Wyzeのアプリ,ファームウェア,クラウドサービスを利用するほうが,安全な選択なように思える。

以下,これら記事を書く上で参照にした記事:
