deye-solar-dashboard

Scripts to export data from a dee inverter with serial no 21xxxx through prometheus to a grafana dashboard. (Tested with firmware MW3_16U_5406_1.53 and MW3_15U)

What it looks like

Setup

The scripts a re running on a rasperry pi

• have the deye inverter in the same network as the raspberry pi. With a fritzbox you can even block the inverter from accessing the internet via "kindersicherung".
• have prometheus, prometheus-node-exporter and grafana installed
• install the prometheus-exporter.sh as a systemd service with a timer
• add your password for the inverter and the inverters ip address to the prometheus-exporter.sh
• tell the prometheus node exporter to collect textfiles from the right directory:
  • put NODE_EXPORTER_ARGS="--collector.textfile.directory /var/lib/node_exporter/" into /etc/conf.d/prometheus-node-exporter
• check if data is logged to prometheus. (all are exported with a solar_ prefix
• configure grafana by importing the dashboard from grafana-dashboard.json

Other useful tools
