Product is not reliable, not worth buying.

Never, ever buy this relay. Not only does it not work with shutdown delays, but also the technical support is disgusting, there is a boor in the engineering service who confidently declares that their device is perfect, and all the problems are in the rest of the electrics.

Pros

Compact size, only 2 modules

Cons

Regular unreasonable shutdown. I turn off 2-3 times a day with a ULo error, as it were, due to low voltage, set a delay to turn off 5 seconds, everything turns off smoothly. There is no low voltage in the network. It is also inconvenient to press two small buttons at the same time to control.
