MQTT Entity helper library for Home Assistant
A Python helper library to manage Home Assistant entities over MQTT.
Updated for device based MQTT discovery.
Features:
- MQTT client based on paho-mqtt
- Retrieve MQTT service info from the Home Assistant Supervisor
- Manage MQTT discovery info (adding/removing entities)
- MQTTDevice class to manage devices
- Availability management (client-wide and optional per-device
availability_topics) - Manage entities per device
- Availability management (client-wide and optional per-device
- Home Assistant Entities modelled as dataclasses:
- Read-only: Sensor, BinarySensor
- Read & write: Select, Switch, Number, Text, Light
- MQTT device events
- Asyncio based
- Helpers for Home Assistant add-ons (optional)
- Add-on configuration modeled as dataclasses
- Load from environment variables, HA's options.yaml or options.json
- Load MQTT connection settings from the Supervisor
- Enable add-on logging (incl colors & debug by config)
- Add-on configuration modeled as dataclasses
Why?
This MQTT code was included in several of my home Assistant addons (SMA-EM / Sunsynk). It is easier to update a single library & add new features, like discovery removal.
Alternative options (not based on asyncio)
