A Wi-Fi socket is a simple and convenient piece of equipment that allows you to remotely turn on and off any load. It was found that when used in "always on and sometimes off" mode, most outlets have a serious problem in the event of a power outage.
A reader wrote to me eika-inc. He uses a large number of Wi-Fi sockets and found that most of the outlets would not turn on when the power was turned off and restored, even though they were turned on before. He tried Yandex, TPLink, Rubetek sockets and everyone has this problem: after turning on the power, the outlet connects to Wi-Fi and is turned off, as if nothing had happened, although it was turned on before. At the same time, of course, no notification comes to the phone.
The only "crutches" that allow you to somehow solve the problem: a lot of timers to turn on (for example, every hour), but this is very inconvenient.
I have two smart sockets (they are in the photo). I tried both. The Yandex socket really always remains off when voltage is applied, but the Blitzwolf SHP-5 socket, which, alas, is no longer produced, remembers its state and turns on if it was turned on before the power disappeared, and it does it in hardware (it turns on even before it is connected to Wi-Fi). If the outlet was turned off before the power disappeared, it turns on for half a second and turns off (this is a glitch).
By the way, most of the sockets of all brands are made on the same platform - Tuya, so the same Yandex outlet can be connect both to the Yandex cloud in the corresponding application and to the Chinese cloud in the Smartlife application or Tuya. At the same time, the Yandex outlet in these applications is called like this. :)
Apparently, there are very few outlets that remember their state after a power outage. There is a chance that the new Blitzwolf can do it too, but not a fact.
