The pool temp sensor is a DSB18B20 on a SonOff TH. Been working fine for years. However every time there are electric problems (blackout, usually with brownout) the sensor stops working and no reboot fixes it. It only comes back after unplugging physically the sonoff.

So when I wake up to no temperature I know I should walk to the other side of the house in the dark machine room and just turn off the whole breaker off and on and it will just come back ‍️

@santi I flashed my Sonoff TH with #esphome and have full control over the power to the sensor. I power cycle the sensor automatically if it doesn’t get valid readings for a minute. Not too difficult to do yourself, but does require removal from the mains power, and a USB-serial adapter.
