Docker conatiner for AC2MQTT

this container is maintained by myself.

Usage

Here is a docker-compose snippet to help you get started creating a container.

docker-compose

Compatible with docker-compose v2+ schemas.

---
version: "2.1"
services:
  ac2mqtt:
    image: backslashh/docker-ac2mqtt
    container_name: ac2mqtt
    hostname: ac2mqtt
    network_mode: host
    volumes:
      - ${CONFIG}/ac2mqtt:/config/ac2mqtt/
    environment:
      - PUID=${PUID}
      - PGID=${PGID}
      - TZ=${TZ}
    restart: unless-stopped

The container needs to use the host network to ensure it runs on the same subnet as your AC units.

Once the container starts you will need to edit your config.yml file with your MQTT host address and username/password.

After you have edited the config.yml file, restart your container.

You can then use a program like MQTT Explorer to watch for the aircon topic to start populating with your AC unit mac addresses.

MQTT Usage

to set values just publish to /aircon/mac_address/option/value/set new_value :

/aircon/b4430dce73f1/temp/set 20

MQTT values

Parameter	Accepted Value	Function
power	ON or OFF	Power on/off the AC unit
temp	16 to 32	Sets the AC temperature. Values are between 16 and 32 and in 0.5 increments. e.g. 20.5
mode	AUTO, HEATING, COOLING, OFF	Sets the mode of the AC unit
homeassist	auto, heat, cool, off	Same as mode but specifically for Home-Assistant. For Home-Assistant integration see home-assistant
fanspeed	AUTO, LOW, MID, HIGH	Sets the fans speed for the AC unit

Home-Assistant

AC2MQTT can be utilised with Home-Assistant using MQTT auto-discovery (https://www.home-assistant.io/docs/mqtt/discovery/)

To enable MQTT autodiscovery in your Home-Assistant configuration.yaml:

mqtt:
  discovery: true
  discovery_prefix: homeassistant
  

Edit your ac2mqtt config.yml file and ensure the following is under the mqtt section:

auto_discovery_topic: homeassistant

The auto_discovery_toipc must match the discovery_prefix in your Home-Assistant configuration.yaml.
