Orvibo Wiwo S20 Smart Socket Now Sells for $16

Orange Pi Development Boards

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.

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.


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.
