Enviro+ MQTT Logger

ghcr.io/raph521/enviroplus-mqtt is a Python service that publishes environmental data from an Enviro+ (or Enviro) via MQTT.

Setting Up Your Device

Set up your RPi as you normally would.
Connect the Enviro+ board, and the PMS5003 sensor if you are using one.
Install the Enviro+ library by following the instructions at https://github.com/pimoroni/enviroplus-python/ (make sure the library is installed for Python 3)

Enviro libraries should not be necessary on host OS. Need to test on base install.
Need to test how to enable sensor without installing full library onto base OS
Need to test whether privileged is necessary, or if /dev can be passed in as volume

The MQTT host, port, username, password and client ID can be specified.
The update interval can be specified, and defaults to 5 seconds.
The initial delay before publishing readings can be specified, and defaults to 15 seconds.
The gas sensor is not available on the enviro, only the Enviro+. Enabling it on the Enviro will not work.
If you are using a PMS5003 sensor, enable it by setting the ENABLE_PMS5003 environment varilable to 1.

Variable	Default	Description
`MQTT_HOST`		the MQTT host to connect to
`MQTT_PORT`	`1883`	the port on the MQTT host to connect to
`MQTT_USERNAME`		the MQTT username to connect with
`MQTT_PASSWORD`		the MQTT password to connect with
`MQTT_PREFIX`		the topic prefix to use when publishing readings, i.e. `lounge/enviroplus`
`MQTT_CLIENT_ID`		the MQTT client identifier to use when connecting
`INTERVAL`	`5`	the duration in seconds between updates
`STARTUP_DELAY`	`15`	the duration in seconds to allow the sensors to stabilize before starting to publish readings
`ENABLE_PMS5003`	`0`	if set to `1`, the PM readings will be taken from the PMS5003 sensor
`ENABLE_GAS`	`0`	if set to `1`, readings will be taken from the gas sensor; should only be enabled on Enviro+, not Enviro

Readings will be published to the following topics:
