I didn't knew I could use automation on a single device like this. I was already trying to get it to work with my external thermometers. My device is saying it's 15 degrees while my thermometer says 19. Maybe if I try an offset of ±4 degrees celcius.. I could get it to start working on holding my desired temperature. I'll give it a go as well!
Yep. Since this one has temp sensor, you can use automation rules based on the device itself.
I also have a Xiaomi Bluetooth thermometer and has a difference of -1,5°C compared to the heater temp sensor.
Will have to perform some tests but don't know for sure if this "auto off" method will be more economic than the auto management in "constant power" mode...
In my previous tests I've adjusted the heater to "auto off" at 19,5/20°C, then makes a 40min break until room temperature goes down to 17,5/18°C and heater "auto on" to keep running for ~25min until reaches again19,5/20°C, and so on;
Theoretically in this way heater is consuming about 875W per hour (2100W working 25min) and in constant mode it should consume 860W! The thing is that I only was able to get this low 860W consume with the above described method of adjusting target temp... Will have to perform some more tests, but I think that won't get this low wattage automatically and so, what method is the more economic.
