Raise temperature for heating pump based on temperature-sensor?

Configuration
1

I have a heating pump and 2 temperature sensors. One in the living room near the heating pump and one in the hallway.

I want to control the heating pumps depending on the sensor in the hallway so it raises the temperature to keep the temperature at a consistent level in the hallway. However, I want to use the temperature sensor in the living room to ensure the heating pump doesn’t push too much heat in case we close the doors unintentionally (so likely, a maximum temperature in the living room is allowed).

Can you set it up using the UI? I guess the condition will take care of the main livingroom, but how can I turn up the degrees in a heating pump depending on a temperature sensor?

I have something similar but with a small electric heater. I use a zigbee temperature sensor.

I created two automations, one that switches the heater on when temperature is below x, on that switches it of when it’s above y.

So yeah that can be done in UI, but it depends on how you control the heating pump I guess… with the heater it’s just a matter of controlling an esphome controlled plug on and off > I can’t really send it desired temperatures in this case… but maybe someone else has a heat pump and can share their setup with you

Thanks Kurt. But thats a trigger for on/off. How do you make sure it starts heating with 1 degree higher so the temperature will increase in the hallway (when very very cold outside)?

I would love to have something like this… essentially…my dream would be to tell the Heat Pump to turn on when the first room drops below it’s set temp (say 20°C) and keep the heat pump running until the last room has reached it’s setpoint+hysteresis.

Sadly, despite having a modulating heat pump that even has a fairly functional HA integration, I simply don’t know how to pull this off.
My heat pump does support a room control mode, but it only obeys it’s own room sensor, and that is unfortunately in the living room (where it tends to be a bit warmer) while the bathroom tends to lose heat faster. I would love to move the thermostat to the bathroom, but it needs a special kind of cable connection that I simply don’t have upstairs.

There is a wireless Vaillant system, but that requires all the components to be the wireless variant, and switching them all out would cost a fortune…:man_shrugging:
