In general, the product is good, but the software part sucks. Do not use sockets for heating appliances or a water heater, they will definitely let you down, they will not turn on according to the scenario, you will not know about it, they will not turn on after a lack of electricity, you will not know about it. A year of operation in the country in conjunction with temperature sensors is a failure. Before that, he was on the sonoff brand, two years as a watch. I switched to in support of ours . alas, no. For all sorts of floor lamps, garlands, and hell, understand for what else - it will roll. Important devices cannot be broadcast to sockets at all. The Chinese are cheaper and more functional.
