I have a Mill heating oven that randomly turns on and then off after a short time. I can’t see any reason why it’s happening, it’s been working for two years without problems.
Any chance the temperature probe is going bad or you have a bad relay in the heater? Are you measuring the temperature from the mill heater?
I can see the state of the heater, I’m just using it as a switch since I’m using an external sensor.
just some thoughts on possibilities.
I assume you are using the generic thermostat then?? Is there a thermostatic control mechanism on the mill heater that could be detecting a lower temperature and kicking on the heater? Is the external sensor possibly sending offline status and this gets defaulted to 0 thus turning on until the external sensor comes back online?
Generic thermostat yes. I have set the thermostat manually to 28C on all of them so that shouldn’t do anything. External sensor updates many times a minute but I use meridian in a minute.
All Mill heaters I have are acting up at the moment, two panel heaters are saying -1 and doesn’t heat at all.
I removed units from Mill app and Home Assistant and added it back. Now everything works.
