Kankun KK-SP3 used to be the cheapest smart socket on the market at around $20, and it is hackable too, but only available with a Chinese / Australian plug, and for some reasons, many sellers stopped selling the device. Last year, a similar product called Orvibo Wiwo S20 launched with US, UK, EU or AU plug types, but sold for nearly twice as much as KK-SP3 at the time. The good news is that the price has gone down considerably, as it can be purchased for around $16 on GearBest, and it’s available on others for $20 to $26 including on Amazon US, DealExtreme, and GeekBuying.
Let’s remind us of the specifications first:
- Material – ABC 94V-0 (fireproof)
- 802.11 b/g/n
- Security – WEP, WPA-PSK or WPA2-PSK
- Power Plug – US, Europe, United Kingdom or Australia plug
- Output Current – 10A
- Output Power – 2000W max.
- Voltage Range – 100-240V AC
- Power Consumption – ≤0.3W
- Dimensions – 10.3 cm x 6.3 cm x 3.7 cm
- Temperature Range – -20 C to 60 C
- Relative Humidity – ≤80%
- Weight – 110 grams
You can control the device with Orvibo’s Android or iOS app. Since it has been around for a while, there’s quite a lot of user’s feedback, and users are usually satisfied.

Orvibo Wiwo S20 is also compatible with Linux based Ninja Block automation box, the communication protocol has been reversed engineered, and an open source app “Orwivo S20 socket manager” has been released, and can be available as a command client client, or with a simple GUI. So beside Wiwo S20 getting cheaper, it has also become more flexible, thanks to the work of the community.
Thank you Onebir!
Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.
Note that the “EU” plug is a very old European standard without ground and it won’t plug in to 90% or more sockets today, as they all have ground that would prevent this plug from being plugged in.
The new model Orwibo Wiwo S20-E2 as on the DX link comes with the ground.
That picture is the first version for the product released in 2014

Only grounded on the back, which is bad. Only usable with Type C plug(not grounded and limited to 2.5A), plugging in a Type F (grounded and limited to 16A) would be dangerous.
backside look’s ok
front seems to missing the ground connection
I think it’s against safety rules in europe
Yes so that not accept european safety regulation on any country. Outer connection can be without grounding but it must be made so it’s not possible put grounded shoket on it.
These things are great. I have a rebranded Arlec one for Australian sockets and it works a treat. Hacked together a bit of java and I can control it programatically without using the Android app.
Would you be willing to share the java code?
there is a safety warning for that in EU: http://ec.europa.eu/consumers/consumers_safety/safety_products/rapex/alerts/main/?event=main.notification&search_term=A12/1577/15&exclude_search_term=0&search_year=2015
Thx a lot! Very important information. Safety is no. 1 pri at any homes.
