What was done
After the vendor went bankrupt, Claude Code analysed a firmware dump and then probed the live device over Bluetooth and a debug probe to work out its protocol, and wrote a local Home Assistant integration.
Where the human stepped in
The author did all physical work (opening the case, wiring a Pico debug probe, dumping flash). Static analysis alone stalled; progress came once Claude could test hypotheses on the live device. Claude kept mining dead ends and needed nudges; the author estimates it worked out about 80% of the device.
