Changed all the switches of other manufacturers, for the switches of this company. By ZigBee they connect directly to the Yandex hub instantly. Work stably without flickering.

This sensor in the ZigBee version is excellent! It has good signal range, it comes with battery, it has an affordable size, and better than anything: Alexa reconits it as a device allowing you to create routines directly on it.
As well as offering scenes/routines within the SmartLife itself, Alexa recognizes it, and that’s wonderful.
It was very difficult for me to find a Zigbee so good so here on AliExpress for an affordable price, now I will make more orders of this model.

The hard one is being the love tax of the thief.

I think the product arrives faster than I thought and the quality is excellent and the water is difficult to get in Korea I’m very satisfied with Ali if I do anything. And if I don’t think of the name of the item, I take a picture and put it up. I think the function of cotton is also very good
