A simple web interface for the Dutch Smart Meter reader (DSMR/ESMR v5). Right now it does only one thing; display a guage to show you the power consumed from or fed back to the grid in real time.
Also exposes the current gauge value in a Prometheus-compatible format on the /metrics endpoint to allow persisting P1 electricity measurements externally and graphing with something like Grafana.
P1 Dash can connect either through a local serial port (using a suitable FTDI serial cable) or to a TCP socket served by ser2net or a dedicated smart meter interface.
Build and run P1 Dash by cloning the repostory and executing the following commands:
git clone https://github.com/martijn/P1Dash.git
cd P1Dash
docker build -t p1dash .
docker run -d --name p1dash -p 5000:5000 --restart=always -v p1dash-storage:/app/Storage --device /dev/ttyUSB0 p1dash
If you intend to use a TCP socket you can omit the --device /dev/ttyUSB0 part.
After startup, visit http://localhost:5000 and click the cog icon to access the settings. dialog in the applciation.
