Mondeer Bluetooth scale: reconstructing BLE weighing and binding

Mondeer Bluetooth scale reconstructs the BLE exchange used by Mondeer and WanKa C1 bathroom scales and implements a Python listener that publishes weighing data to Home Assistant over MQTT. The documented work combines decompilation of the original Android app with traffic observation; a separate Android companion app displays readings and exports to Health Connect.
