homewizard-p1-prometheus

A Prometheus exporter for the Homewizard P1 energy monitor

Running the exporter

To run the application you need to specify the IP address of the P1 meter in your network as an environment variable HOST

HOST={IP_ADDRESS} go run main.go

You can also define a TICK in second which specifies in which interval the exporter will fetch data from the P1 monitor. The default tick interval is 10seconds.

The exporter will listen by default on port 9898 which can be changed by defining an environment variable PORT.

Docker

The exporter can also be run as a docker container like

docker run --rm -p 9898:9898 -e HOST={ID_ADDRESS} chriskies/homewizard-p1-prometheus:latest
