Hello, product Description OK, delay 6 days OK, so no notice in French (English, Spanish, German, Polish, Russian (garbage poutine!), despite this we manage on the net, I had ordered 2 units of wifi with control and programming by the smartphone, No problem with the adapters. The next morning 24 ° in the rooms when the instructions were of 2 °. So not at all satisfied. Luckily I had only ordered 2 so far and thought to re-order 10, I handed over my 2 good old faithful Danfoss for 25 years
In short I am not satisfied with this product.

There is no problem working, I recommend it

What can I say for the device, I have an Alice midi, with a built-in ZigBee, the station saw the relay immediately, but did not want to control it, when you press the relay through the application, nothing happened except the sound of the Alisa, but the light turned on from the button on the relay. But the time from the fifth re-pairing with Alice everything started working, the only thing if the lights were turned off and turned on is that the lamps will be on and in the settings of the smart home with Alice there is no adjustment of the relay position when the power is supplied, about which I have already written to the developers, they promise to add this function. Connecting this relay without zero turned out to be all just phase from the wiring to the terminal L, and the other two wires to L1 and L2. Then take three short wiring and connect the switch to the relay, where the phase entered it, connect to the COM terminal on the relay, and the other two in any sequence. If something does not work, try to remove the LED that you have in the switch, but by the way I put the relay in the switch on two buttons

Works great. Connected through the Tuya smart app without problems, and integrated with Alice

The main garnum. At the first glance, she is important. Protesting-pratsyu, now force it to the storm and change the spot.
