bos_heater_mqtt

Expose a Braiins OS miner as a heater in Home-Assistant using hvac MQTT

This is still WIP. Not ready for use

Warning: You will need to have an independent/third paty temperature sensor as there are no temperature sensor reflecting room temperature inside the AntMiner

Installation

To install, on the antminer, after installing BraiinsOS

Run the installer

# sh -c "$(wget https://raw.githubusercontent.com/matfra/bos_heater_mqtt/main/install.sh -O -)"

Home-assistant configuration

First, we will need to make sure that you have a temperature sensor that is published on your MQTT server. There is a trick, you can publish any already existing temperature sensor to MQTT using home assistant itself.

Example of automation.yaml file to do just that:

- alias: publish_ble_temperature_livingroom
  trigger:
    - platform: time_pattern
      seconds: "/20"
  action:
    service: mqtt.publish
    data: {"payload": "{{ states('sensor.ble_temperature_livingroom') }}", "topic": "sensors/ble_temperature_livingroom", "qos": 0, "retain": 0}
