These German smart sockets plug into your mains power outlet and allow you to control the output either locally or remotely by a variety of means.
Now, first off the bat these are not as cheap as the Chinese versions, they are made in Germany and at least to Spain I got rapid delivery. I suggest they mean 16Amps non-inductive load – so just as with the Chinese versions I’d be very wary about attaching a 16 amp heater. At 220v I’m thinking a 2KW heater should be fine – but I’ve not tested that yet as it is WAY too hot here in Spain to test any kind of heater.
There is an on-off manual override button on the top…. with a red light – OFF when off, dim RED when ON. I plugged them into the mains one at time after grabbing the Android App “Smart Life” – there is handily a QR code for this on the side of the boxes they come in.
As it happened I already had an account with this APP as I must use it for other stuff but that’s easy.
