Broadlink IR Blaster + dual-temp thermostat

I’m attempting to control a window AC and a portable electric heater by using the dual-temp thermostat integration. Both appliances are fully set up through the Broadlink integration. When I created the switch template in the configuration.yaml file, I get the following errors. The errors are pointed at the line for the ‘turn_on’ and ‘turn_off’ commands.

Configuration warnings
Invalid config for 'switch.template' at configuration.yaml, line 61: Unable to determine action 'switches->br_ac->turn_on->0', got None
Invalid config for 'switch.template' at configuration.yaml, line 69: Unable to determine action 'switches->br_ac->turn_off->0', got None

This is the Climate configuration:

climate:
  - platform: dual_smart_thermostat
    name: br_climate
    heater: switch.br_heat
    cooler: switch.br_ac
    target_sensor: sensor.br_th_temperature
    min_temp: 55
    max_temp: 85
    ac_mode: false
    target_temp: 73
    #target_temp_high: 73
    #target_temp_low: 71
    min_cycle_duration:
      seconds: 60
    keep_alive:
      minutes: 3
    #initial_hvac_mode: "heat"
    precision: 0.1
    target_temp_step: 1

This is the Switch template configuration:

switch:
  - platform: template
    switches:
      br_ac:
        turn_on:
          sequence:
            - service: remote.send_command
              target:
                entity_id: br_remote
              data:
                device: br_ac
              command: power
        turn_off:
          sequence:
            - service: remote.send_command
              target:
                entity_id: br_remote
              data:
                device: br_ac
              command: power
      br_heat:
        turn_on:
          sequence:
            - service: remote.send_command
              target:
                entity_id: br_remote
              data:
                device: br_heat
              command:
                - power
                - oscillate
        turn_off:
          sequence:
            - service: remote.send_command
              target:
                entity_id: br_remote
              data:
                device: br_heat
              command: power

Any suggestions? I verified that the above configuration doesn’t work.
