Tesla Powerwall and Solaredge inverter monitoring with Zabbix
Recently I had to debug a strange behavior in my photovoltaic system. I needed data history from a Tesla Powerwall 2 (with backup module) and a SolarEdge HDWave inverter.
Both the battery and the inverter and accessible from local LAN, and I really dislike to rely on external websites, so I decided to have a look to get the raw data directly from the appliances. I already use Zabbix for monitoring and Grafana for dashboards, so my goal was to stick with them. Sadly, I wasn't able to find a Zabbix template for that purpose (but there's some for Grafana) - I had to change the Grafana script to a Zabbix external script and template.
