Homelett ABS 4CH PRO R2-4 Gang Smart WiFi, DIN Rail Mountable, 3 Modes-Self Locking, Inching and Interlocking Compatible with Alexa, Google Assistant, Nest, IFTTT (Multicolour)

This is an excellent product and can be configured in multiple ways. We also use the RF remote to make sure that dependency with WiFi service is not a limiting factor. The documentation is very poor and one needs to have the patience to get going.

Very unreliable piece of tech. One of the four switches has been malfunctioning since 1 week after the purchase. I had to courier it twice after talking to the seller and they even changed the PCB but the problem was never solved. The seller refused to replace the defective device and I am stuck with it now.

By far the cheapest and best operating automation device. I searched a lot online and even in stores as well but this the best choice i have got. I installed 7 of this in my house and it can operate fans, AC, Multiple lights, single light almost everything. Also it allows to use the switches of board as well.

Nice product
