The full story

Four days into using Home Assistant, the poster credits Claude with helping bring their energy setup to life. It manages a 12 kWp solar system with a SolaX X3-Hybrid G4 inverter, 34 kWh of battery storage and a SolaX EV charger, with the inverter controlled locally over Modbus TCP on time-of-use pricing.

The automations include battery management to maximise self-consumption, solar forecasting for battery optimisation and BMS calibration, EV charging from excess solar, dishwasher scheduling on solar surplus, peak grid alerts and daily energy reports. The dashboard is built entirely in Home Assistant's native system.

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.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
