Same device for heater and cooler

[grinco]

Hey there, for air-to-air heatpump users, it would be useful if we could use the same climate device for both heating and cooling the room. The only difference is climate operation mode. Tried adding the same climate device to both heating and cooling entities, and it only heats the room.

Thanks for the great work!

Have you tried creating template-switches for your climate device? That gives you two separate switches, which will act on the same climate device. One switch for heating, one for cooling.

Like this, to give you an idea:

switch:
  - platform: template
    switches:
      heatpump_heating:
        value_template: "{{ is_state_attr('climate.heatpump', 'hvac_action', 'heating') }}"
        turn_on:
          service: climate.set_hvac_mode
          target:
            entity_id: climate.heatpump
          data:
            hvac_mode: heat
        turn_off:
          service: climate.turn_off
          target:
            entity_id: climate.heatpump
      heatpump_cooling:
        value_template: "{{ is_state_attr('climate.heatpump', 'hvac_action', 'cooling') }}"
        turn_on:
          service: climate.set_hvac_mode
          target:
            entity_id: climate.heatpump
          data:
            hvac_mode: cool
        turn_off:
          service: climate.turn_off
          target:
            entity_id: climate.heatpump

Great idea, I'll certainly give it a try. Thanks for the tip.

Glad I could help. I want to add, that you'll probably need two custom scripts, too:

• script.turn_off_heatpump_from_cooling
• script.turn_off_heatpump_from_heating both with a condition, to only turn off the heating if it's actually heating and only turn off cooling, if it's actually still cooling.

Otherwise, if one switch is turned on, before the other one turned off, the last switch will override the hvac mode, effectively turning off your heatpump, even if it should be heating/cooling.

It worked quite nicely even without the scripts. Didn't look at the logs if it turns off the cooling before switching on heating, or goes straight to heating - but it works. Tried playing with the temperatures and different modes - all good. One of the things that I did notice, is that sometimes when temperature is close to or at target, the thermostat says it's off, while it doesn't really turn off the switch - so the heat pump is on idling..

I'll reproduce it then report a bug. Thanks again for the hint with the template sensors - completely didn't occur to me.
