EZMonitor is a lightweight KDE Plasma 6 applet that displays real-time data from your solar inverter.

Developed for the APsystems EZ1 microinverter series, it connects to the local JSON API provided by the device and shows:

🌞 Live panel power (in Watts)
📊 Daily yield (in kWh)
🔄 Updates every 10 seconds

No cloud service, no third-party backend – all data stays local.
