Over the last few years I’ve spent a considerable amount of time working with the Prometheus monitoring system and time series database in combination with the Grafana visualization platform.
I had been wanting to track the temperature and humidity of a few rooms and was looking for an excuse to run a Prometheus server at home.
I thought it would be neat to use a Wi-Fi microcontroller to collect this sensor data and expose it directly in the Prometheus simple text-based exposition format.
