Mara X Monitoring

Capture temperature data from a Lelit Mara X espresso machine via a serial connection and persist in a database and expose via grafana.

Docker will persist DB storage using volumes so restarts won't cause data loss.

Tested on a Raspberry Pi.

All credit to the author of this post for doing so much of the ground work!

How to run

Run grafana / influxDB / ingestion via docker-compose with the following

[sudo] docker-compose up --build

This can now be backgrounded.
