MQTT Climate Sync

A Home Assistant component for syncing IRHVAC messages received by Tasmota IR transmitters/receivers with climate entities.

For an all-in-one solution, I highly suggest you to use the Tasmota-IRHVAC component.

Installation and configuration

1. You can install the integration either by searching for it in HACS or by adding the custom_components/mqtt_climate_sync folder to your local custom_components folder (if it doesn't exist you can create it).
2. Add the following code to configuration.yaml, where YOUR_MQTT_TOPIC is the MQTT topic where your IR receiver sends the received signals (for example, ir-receiver/tele/RESULT), and YOUR_CLIMATE_ENTITY is the entity you want to sync (for example, climate.air_conditioner). If you need to, you can add multiple configurations with dashes (-).

   mqtt_climate_sync:
   entity_id: YOUR_CLIMATE_ENTITY
   topic: YOUR_MQTT_TOPIC

   mqtt_climate_sync: # With multiple configurations
   - entity_id: YOUR_CLIMATE_ENTITY_1
     topic: YOUR_MQTT_TOPIC_1
   - entity_id: YOUR_CLIMATE_ENTITY_2
     topic: YOUR_MQTT_TOPIC_2

Events

Every time the component syncs IR data, it fires an event called mqtt_climate_sync_state_changed. This events contains a turned attribute, which returns on or off, state which is equal to the climate entity's state, temperature, which is equal to the temperature and fan_mode, which is equal to the fan mode. With this event, you can set up automations like this one, which sends a notification to your mobile phone when your air conditioner is turned on with a remote control.

    automation:
      alias: Air Conditioner turned on
      initial_state: true
      trigger:
        platform: event
        event_type: mqtt_climate_sync_state_changed
        event_data:
          turned: 'on'
      action:
        service: notify.mobile_app
        data:
          title: Air Conditioner turned on
          message: Your Air Conditioner was turned on with a remote control

Notes

• This component syncs only the HVAC mode (off, cool, heat, fan only, etc.), temperature and fan mode (low, medium, high, auto, etc.) attributes.
• The MQTT data the component receives needs to be in HVAC (the Tasmota JSON structure looks like this: {"IrReceived":{"Protocol":"GREE","Bits":64,"Data":"0x0x0904405002200090","Repeat":0,"IRHVAC":{"Vendor":"GREE","Model":1,"Power":"On","Mode":"Cool","Celsius":"On","Temp":20, ...)
