dyson-lamp-ble: reconstructing local control of a Dyson lamp

dyson-lamp-ble reconstructs local control of a Dyson BLE lamp from MyDyson Android app analysis and device observations. Its Python library and CLI obtain an account-issued long-term key, perform the BLE session handshake and send power or synchronized-mode commands. The protocol notes describe GATT characteristics, HKDF-SHA256 key derivation and message framing.

Requirements & limits

Prerequisites: Python 3.11 or later and the ble extra are required for local control.
Prerequisites: An owned Dyson BLE lamp and an account-issued device key are required; fetching the key uses the cloud extra and account access.
Limits: Colour-temperature and brightness mappings are currently raw 16-bit values.
