Ruuvibridge Ruuvitag MQTT discovery for Home Assistant

This provides alternative MQTT discovery for ruuvitag measurements published via https://github.com/Scrin/RuuviBridge/. Ruuvibridge is great and I recommend using it for parsing measurements from Ruuvi Gateway however it's Home Assistant setup didn't suite my needs.

Building and testing locally

Create haconfig directory for homeassistant config directory

Build and run:

docker-compose up -d --build

Running with Home Assistant

Simples way is to run it using docker-compose.yml. The latest versio is available direct from Docker Hub so no need to even build it locally.

version: "3.4"
services:
  mqtt:
    image: eclipse-mosquitto
    volumes:
      - ./mosquitto.conf:/mosquitto/config/mosquitto.conf
  ruuvibridge-ha-mqtt:
    image: mikakoivisto/ruuvibridge-ha-mqtt:latest
    links:
      - mqtt
    env_file: 
      - docker.env

Configuration

Add following to docker.env file

MQTTHOST=mqtt
MQTTPORT=
MQTTUSER=
MQTTPASS=
RUUVITOPIC=ruuvitag
HASSTOPIC=homeassistant/status
DEBUG=app:info,*:error,spa:info

You can also limit which attributes are exposed to Home Assistant with RUUVIATTRIBUTES environment variable. Example:

RUUVIATTRIBUTES=temperature,humidity,pressure,dewPoint,batteryVoltage

Home Assistant object id is {mac}_{attribute}. The mac is without : and lower case. You can also add prefix to it if you want to prefix them with say ruuvitag or ruuvi by setting RUUVIOBJECTIDPREFIX. Example:

RUUVIOBJECTIDPREFIX=ruuvitag

This will cause it to generate the sensor object id as ruuvitag_{mac}_{attribute} for example tag with mac CC:2B:E2:4A:E1:59 will have temperature sensor object id sensor.ruuvitag_cc2be24ae159_temperature. Without the prefix it would be sensor.cc2be24ae159_temperature
