Dynamically update target temperature within a schedule-triggered automation

Configuration
1

I have an automation that sets my thermostat target temperature based on a schedule with different temps for schedule on and off (In the code below, the target temperature is 17/7 in on/off)

alias: livingroom_set_temp_scheduled
description: Set livingroom thermostat to on and off temps
trigger:
  - platform: state
    entity_id: schedule.thermostat_schedule_livingroom
action:
  - service: climate.set_temperature
    target:
      entity_id: climate.lumi_lumi_airrtc_agl001_thermostat_2
    data:
      temperature: >-
        {{ iif(trigger.to_state.state == 'on', 17, 7) }}
      hvac_mode: heat
 mode: single

I am trying to edit this so that the target temp for the schedule ‘on’ periods is read from an input_number (input_number.schedule_target_temp_livingroom) and that the device target temperature updates when the corresponding input button (input_button.set_schedule_temp_livingroom) is pressed

I have tried the following:

alias: livingroom_set_temp_scheduled
description: Set livingroom thermostat to on and off temps
trigger:
  - platform: state
    entity_id: schedule.thermostat_schedule_livingroom
action:
  - service: climate.set_temperature
    target:
      entity_id: climate.lumi_lumi_airrtc_agl001_thermostat_2
    data:
      temperature: >-
        {{ iif(trigger.to_state.state == 'on',
        states('input_number.schedule_target_temp_livingroom'), 7) }}
      hvac_mode: heat
  - if:
      - condition: state
        entity_id: input_button.set_schedule_temp_livingroom
        state: "on"
    then:
      - service: climate.set_temperature
        target:
          entity_id: climate.lumi_lumi_airrtc_agl001_thermostat_2
        data:
          temperature: >-
            {{ iif(trigger.to_state.state == 'on',
            states('input_number.schedule_target_temp_livingroom'), 7) }}
          hvac_mode: heat
mode: single

But this only updates the target temperature at the next schedule switch from off to on.

Any suggestions as to the best way to update the target temperature in this scheduled automation?

From the above I suspect that what you actually want is as follows:

alias: livingroom_set_temp_scheduled
description: Set livingroom thermostat to on and off temps
trigger:
  - platform: state
    entity_id: schedule.thermostat_schedule_livingroom
    variables:
      t_state: "{{trigger.to_state.state}}"
  - platform: state
    entity_id: input_button.set_schedule_temp_livingroom
    variables:
      t_state: 'on'
action:
  - service: climate.set_temperature
    target:
      entity_id: climate.lumi_lumi_airrtc_agl001_thermostat_2
    data:
      temperature: >-
        {{ iif(t_state == 'on', states('input_number.schedule_target_temp_livingroom'), 7) }}
      hvac_mode: heat
mode: single

Thanks @Didgeridrew . I tried what you suggested, but it gave a malformed data error. I changed the second trigger statement from a condition: state declaration to a platform:state declaration and this updates the target temperature. However, the behaviour is not quite as I want, because it also updates the target temperature when the schedule is “off”.

What I am trying to do is:

  • if schedule is off thermostat target temp is fixed at 7.
  • if schedule is off, and input_button is pressed, target temp remains at 7 until the next time that schedule is on and then target temp is set at the value of schedule_target_temp_livingroom at the time of input_button press
  • if schedule is on, and input_button is pressed, update input_button.set_schedule_temp_livingroom to the value of schedule_target_temp_livingroom the time of input_button press

To block the button from doing anything while the schedule is “off”, you can add a condition to check that the t_state variable is the same as the schedule’s state.

alias: livingroom_set_temp_scheduled
description: Set livingroom thermostat to on and off temps
trigger:
  - platform: state
    entity_id: schedule.thermostat_schedule_livingroom
    variables:
      t_state: "{{trigger.to_state.state}}"
  - platform: state
    entity_id: input_button.set_schedule_temp_livingroom
    variables:
      t_state: 'on'
condition:
  - "{{ is_state('schedule.thermostat_schedule_livingroom', t_state) }}"
action:
  - service: climate.set_temperature
    target:
      entity_id: climate.lumi_lumi_airrtc_agl001_thermostat_2
    data:
      temperature: >-
        {{ iif(t_state == 'on', states('input_number.schedule_target_temp_livingroom'), 7) }}
      hvac_mode: heat
mode: single
