A Fronius solar integration repaired against a simulated inverter

The full story

The rework addresses missing registration, network exceptions, null night-time power values and inconsistent measurement frames in a proposed Fronius integration. It includes named values and recovery handling for a failing or unreachable inverter.

The author reports running emonHub against a simulated inverter and testing outages, invalid data and recovery. They explicitly say the change had not yet been tested on a real Fronius inverter.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
