I’ve had a look at several Wi-Fi smart sockets recently. Broadlink SP2 comes with a Chinese plug and supports power monitoring (About $40), Kankun KK-SP3 is more basic but sells only for $20, and runs OpenWRT, and Orvibo Wiwo S20 does not support power monitoring either, but is available with US, Europe, United Kingdom or Australia plug (About $40). If you want a Wi-Fi smart socket with a EU plug, there’s another option: W908I selling for $32 on Chinavasion. Based on the manufacturer website (HaiDian Technology) however, there are four W908I models with US, EU, UK, or AU plugs, as well as four W908II models with a higher power ratings (4400W).
W908I / W908II specifications:
- 802.11 b/g/n
- Sensitivity – 802.11b: < -84dBm; 802.11g: < -68dBm
- Output power – 802.11b: 16 ±2dBm; 802.11g: 13 ±2dBm
- Security – WEP, WPA-PSK or WPA2-PSK
- Wall Socket Power Plug – US, Europe, United Kingdom or Australia plug
- Input Sockets – 3-pin, 2-pin, and USB
- Output Current – W908I: 10A max; W908II: 20A max.
- Output Power – W908I 2200W max; W908II: 4400W max;
- Voltage Range – 90-260V AC @ 50-60 Hz
- Power Consumption – ≤0.8W
- Dimensions – 11.2 cm x 6.4 cm x 7.0 cm
- Temperature Range – -20 C to 75 C
- Weight – 116 grams
The app to control the smart socket is available for Android and iOS, and can be downloaded by scanning the QR code at the back of the socket. Their appears to be a web interface too. Power monitoring function is not available in W908I/II. By the way, Broadlink SP2 does have this function, but it stopped to work on my sample after about a month.
As mentioned above, the W908I-Euro is available on Chinavasion for just $32, but other W908I plug types are available on Aliexpress for prices between $35 and $50, and a few shops sell W908II for about $60.
Thanks to Onebir for the tip.

The QR code visible in the pictures on Chinavision links to http://188.8.131.52/Server/index.html where we can download the android app.
So what does the app look like and where can I download it scanned QR code get all-sorts of rubies that doesn’t work please employ someone who has just a small amount of English instead of writing in jibarish think it would be better to just stop buying Chinese shit everything electronic from China as shit instructions or is just cheap rubbish that 9.9out of 10 doesn’t work. If it says it’s from China don’t buy it as for refund 9.99 times out of 10 you will lose your case if you are lucky enough to get a reply you won’t be able to make any sense of what it says
Thanks! My phone camera is broken so it did not work. Online services did not help either.
IP instead of domain name? This doesn’t feel confidence 🙂
I bough one Kankun for research purpose. Well spend 15 €.
That kind of plug is only rated at 2.5A according to European regulations, so this product couldn’t legally be sold in Europe.
Can you turn the USB port on and off or is it just for charging?
Como fazer a programação para ligar e desligar (W908I) (i_SMART)
Tenho 3 tomadas, somente uma funciona através de internet, esta o Firmware é version:2.92(mar.24.2015.sk), as outras e versão 2.83, como faço para atualizar.
Received W908I. Order was for US plug they sent UK version. Instructions are written in English fairly well. 1st step in the instruction booklet is to download the app. Nowhere is it written were to download the app. and nowhere on the packaging shows the company name . If it wasn’t for this forum I wouldn’t know where to get the app. That being said after scanning the QR code on the product it goes to dead link. How does a company like this stay open. Waste of time and money.
