Lumalou Revival: reconstructing the lamp's encrypted BLE control

Lumalou Revival reconstructs control of the Fisher-Price Lumalou lamp after its app was discontinued. An ESPHome bridge and Python client implement the documented MPID BLE exchange, including ECDH session setup, AES-128-CTR packets and framed sound-and-light commands. The reference lists 68 opcodes; the author reports testing on one lamp.
