Electronics

When your loft flat turns into a sauna every summer, the logical solution is obviously to reverse-engineer a decades-old proprietary bus protocol. The final implementation makes an ESP8266 impersonate the bus by abusing UART at 5924 baud.

How I reverse-engineered my electric sofa to work with Home Assistant using an ESP32. After frying a transistor and some emergency soldering, I now have a voice-controlled couch.
