The full story
hopchat lets you control your home by chatting from the terminal, for example "@home dim the living room lights". A local AI model turns this into actions for Wiz lights, LG TVs and, more recently, Home Assistant devices, and nothing goes to the cloud. It is also an encrypted chat app for people on the same Wi-Fi, built on the Offline Protocol SDK with a Rust ratatui interface.
The poster used Claude Code throughout, from wiring up the SDK and peer discovery to writing the drivers for Wiz, LG webOS and Home Assistant.
