Home assistant : Climate object for room and LWT temperature

[trantoriana]

Hi,

I have been working on a home assistant MQTT templated climate object which hides the MQTT control behind this single climate object. This means that in your automations you set the temperature of the climate object and the climate object will translate that in a valid P1P2 command (including HEX conversion) and send it to P1P2 over MQTT.

Please mind that not all settings are implemented yet.

The LWT (Leaving Water Temperature) is defined as follows:

- name: LWT Daikin
  retain: false
  qos: 0
  payload_on: 1
  payload_off: 0
  # Room temperature
  current_temperature_topic: P1P2/P/155/T/1/Temperature_Leaving_Water
  current_temperature_template: >-
    {{ value | float | round(1) }}
  # Target temperature
  temperature_state_topic: "P1P2/P/155/S/0/Target_Temperature_Heating_Zone_Main_Abs"
  temperature_state_template: >-
    {{ value | float | round(1) }}
  temperature_command_topic: "P1P2/W"
  temperature_command_template: >
    {{ 'E36 6 %04X' | format(((value | float) * 10) | int) }}
  # Temperature dial
  min_temp: 40
  max_temp: 55
  temp_step: 1
  modes:
  fan_modes:

It is fairly simple, does not have a mode or fan.. It is just to set the leaving temperature.

The thermostat I have in the living room is a Madoka and the following climate object correctly reads:

• Actual room temperature
• Target room temperature
• Fan mode
• Operation mode

It correctly sets:

• Target room temperature

At this moment it does not:

• Set the fan speed (silent mode)
• Set operation mode (On off, heat, etc)

The commands are redirected to a dummy MQTT topic (P1P2/W-XX) to prevent messing with the Daikin settings

- name: Living room Daikin
  retain: false
  qos: 0
  payload_on: 1
  payload_off: 0
  # Room temperature
  current_temperature_topic: P1P2/P/155/T/0/Temperature_Room
  current_temperature_template: >-
    {{ value | float | round(1) }}
  # Target temperature
  temperature_state_topic: "P1P2/P/155/S/0/Target_Temperature_Room"
  temperature_state_template: >-
    {{ value | float | round(1) }}
  temperature_command_topic: "P1P2/W"
  temperature_command_template: >
    {{ 'E36 0 %02X' | format(((value | float) * 10) | int) }}
  # Temperature dial
  min_temp: 19
  max_temp: 24
  temp_step: 0.5

    {% set modes = { '0':'off', '1':'heat',  '2':'cool', '3':'auto'} %}
    {{ modes[value] if value in modes.keys() else 'off' }}

  fan_mode_state_template: >
    {% set modes = { '0':'high', '1':'medium',  '2':'low'} %}
    {{ modes[value] if value in modes.keys() else 'off' }}
  fan_mode_command_topic: *commandTMPTopic
  #fan_mode_command_template:
  fan_modes:
    - low
    - medium
    - high

An example of how to set the temperature in a automation:

action:
  - service: climate.set_temperature
    data:
      temperature: 21
    target:
      entity_id: climate.living_room_daikin

Comments and improvements welcome.
I will post further changes if this is appreciated.

Adapt the command you need to send in the relative:

• *_command_template

lines..
In the example above room target temperature is set using (E36 0 %02X) madoka controlled setting.
