General PID functionality requested

[heikone]

Good afternoon,

I would to like ask for a feature request for my use case:
I got a combined temperature measurement of temperature below and above wanted temperature of each room in my house.
This difference could be like -1°C when a temperature is 1K below the wanted temperature of for example 20°C.
To control this temperature difference to 0K, the leaving temperature offset of my heat pump can be adjusted from -10K to +10K.

The solution I'm asking for is to have a general PID controller.

The current solution of this repository allow to switch between heating and cooling (manually), but I didn't find a proper way to combine it to my use case to control a certain sensor measurement to a target value by adjusting an input value.

I would like to get your feedback and questions!

Greetings,
Heiko
