I Cut My Withings Scale Out of the Cloud with an ESP32

I Connected My Withings Body+ to Home Assistant with an ESP32

A developer reverse-engineered the Bluetooth protocol of his Withings Body+ scale so it syncs directly to Home Assistant via an ESP32, bypassing the Withings cloud entirely. He used an AI coding agent to decompile the Withings Android app and build a custom ESPHome component, testing it with repeated weigh-ins. The result: weight, body fat, and other metrics update locally for two profiles, with no Wi-Fi needed on the scale.
