I have a couple Sonoff S26r2 smart switches in my house that control a light and my Christmas tree lights. But three nights in a row now, they light become unavailable in HA and the automations fail. It kind of defeats the purpose of having a smart switch if I have to reset them every day. I am using the Sonoff integration. To get the switches back on line, I just log into my ewelink account and turn the switch off/on. So Ewelink still sees the switches, but HA they are unavailable(until I swith on and off in ewelink). Any thoughts, are these just cheap smart pluts, are there more reliable ones?
