Andreas WredeandClaude Sonnet 5 918003d2e3 ha: add carefree_bt12 integration for the Carefree Connects awning
Commands reverse-engineered from Bluetooth HCI snoop captures (adb bugreport)
of the official Carefree Connects (BT12) Android app, confirmed across three
independent captures including two isolated single-action live tests:
extend/retract (feature 0x05, values 0x01/0x02 -- the device toggles motor
state internally, there's no separate stop byte) and light on/off (feature
0x1a, values 0x19/0x01). Both live under GATT characteristic 02060002 on
service 02060001-50e1-405f-bab0-6bb582b4d96e.

Connects on demand per command (mirrors the app's own connect/act/disconnect
pattern) rather than holding a persistent connection like li3_battery, since
this device doesn't stream telemetry. Cover/light state is assumed/optimistic
-- the notify channel (02060003) isn't decoded yet, so a diagnostic sensor
just surfaces raw undecoded replies to build up data for that follow-on work.

Verified end-to-end against the real device: light on/off and awning
extend both worked through Home Assistant.

"""Diagnostic sensor exposing raw BT12 notify replies, undecoded.
The notify channel (02060003) isn't reverse-engineered yet. This entity just
surfaces whatever comes back after each command, in order to build up real
data for that follow-on work -- don't assume the values mean anything yet.
