Looking for ideas how to use heat pump thermostat with external temperature

[jaco]

I've encountered a challenge that I hope someone here might help me solve :)

The heat pump's internal thermostat is located in the boiler room, where the temperature is consistently around 33°C (91°F). Unfortunately, relocating this sensor into the living spaces is not an option for me. I want to consider temperatures from several rooms in my home, not just a single location, to achieve a more balanced and efficient heating control.

I can create virtual thermostat in HA to control heat pump (altering heat curve, enabling powerful mode?) but I am afraid that hysteresis a little to dumb and not efficient :)

Ideal solution will be to somehow overwrite panasonic's thermostat temperature from HA.

Look for node-red integration, it can drive +5/-5 curve shift to desired temperature.. as for input you could make your own logic (for example pick lowest room temperature) and pass it as target temperature..

I don't have any problems with automations but with that "own logic" :) I understand hysteresis and that I can do but anything else is foreign…

How would you alter heat curve if you want to make, for example -7°C change to room temperature?

Or maybe there is a way to connect external room temp sensor directly to heap pump and emulate that sensor? :)

Yes, use room thermistor, i think it's possible to emulate via optional pcb.. but really try node-red.. it's awesome project.. and with right compensation curve, +3/-3 range is more than enough

It can be roon in HA, also it's possible to control from HA

I'm using since 3 seasons thermostat (to be precise 2 thermostats) in Node red , each for each floor.
Together with Optional PCB emulation gives me good results , since this thermostats drive zone 1 and zone 2 ( Heishamon with optional PCB emulation drives also water flow pumps for each zone).

In nodered i have also monitor , when there is a defrost both water flow pumps run ( this HP havn't forseen).
