If I select Device > my pump I have 2 actions to choose from, “change HVAC mode on Daikin” and “change preset on Daikin” … tried here to add your code: turn_off: service: climate.set_temperature target: entity_id: climate.heat_pump data: temperature: 15. but that didnt work.
Find the circuit breaker controlling your HVAC system. Now flip it to ‘off’ position. Wait approximately 30 seconds for the reset process to run. Flip the breaker once more to ‘on’ position. Head back to your thermostat and select the desired setting mode (heat/cool). Also adjust the temperature settings as necessary.
