What people report

Fronius inverters and meters work locally over the Solar API; some Gen24 firmware caused connection and SSL issues.

Fronius inverter	Works Local	Works out of the box using local API; occasional disconnects Saved copy Fronius works out of the box using local API. Mine is up for almost 4 years now, no problems except occasional disconnects. Excerpt saved from the Arctic Shift Reddit archive on 2026-10-23.	Reddit comment · 2024-03
Fronius inverter and Smart Meter	Works	Works well out of the box; heat pump raises temperature when sunny Saved copy IDM and Fronius owner here. I have about 90 entities that i can use in HA from my Heatpump (Temperatures, working times, ...). IDM and Fronius works also good out of the box. You can automatically raise the temperatures when the sun is shining. IDM need the Fronius Smart Meter to recognise it when you have to much PV Power. All you need is a Internet connection on both devices. Mehr Informationen gerne auf Deutsch 😀 Excerpt saved from the Arctic Shift Reddit archive on 2026-10-23.	Reddit comment · 2024-05
