SolarPower

OpenDTU

My "Balkonsolaranlage" uses OpenDTU to query the rf data of the microinverter TSOL-M800 from TSUN (Hoymiles HM600 compatible).

Monitoring Setup

• http://OpenDTU1
• mqtt@job4 (mosquitto_sub -v -t 'OpenDTU1/#')
• job4:/etc/systemd/system/openDtu2Db@OpenDTU1.service (sudo systemctl status openDtu2Db@OpenDTU1.service, sudo journalctl -f -u openDtu2Db@OpenDTU1.service)
  • python -u /home/joachim/bin/openDtu2Db.py OpenDTU1 (prints to stdout)
• Influx database openDtu (influx -database openDtu -precision rfc3339 -execute "select * from string order by time desc limit 10")
• Grafana Source openDtu@InfluxDB
• Grafana Dashboard https://banzhaf.chickenkiller.com/grafana/d/_rNE2oO7k/stromverbrauch?orgId=1&refresh=10s&viewPanel=7

Troubleshooting

• Sometimes mqtt connection gets lost (see https://github.com/tbnobody/OpenDTU/issues/965)
  Go to http://opendtu1/settings/mqtt, hit "Save". Should fix it
