Hello
I am using an mcp4725 to emulate an analog pt1000 temperature sensor connected to a district heating box from Danfoss. It works reasonably well, but the accuracy is not great.
I get the source temperature value from a (group of) sensor(s) in HA.
I can also read the target temperature in HA. They can differ up to a couple of degrees in a non-predictable way.
I was thinking: is it possible to create a loop that reduces or increases the voltage out of the mcp4725 incrementally until the two values are equal, and make it run forever?
Excuse me, I am not English and not a programmer.
Yours truly
