parser.py is a verbatim port of li3/van-li3-battery and still had the old
"000000" string gate and raw int(parts[7]) current. Apply the identical
fixes (72487cf) so the native integration and the MQTT bridge agree:
- status gate and decode_status share one parsed-int helper (0 == OK in any
representation; unparseable = unreliable)
- main-pack current parsed at its real 0.1 A scale
The 72487c MQTT/systemd/discovery/expire_after hardening intentionally does
not appear here: parser.py is protocol-only, and coordinator.py already uses
bleak_retry_connector + HA bluetooth discovery + native sensor availability
in place of those standalone concerns.
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.

The li3 BMS has a persistently marginal BLE link from any single fixed
vantage point on this Pi (onboard adapter, a USB dongle that turned out to
be BR/EDR-only, and the Athom ESPHome BT proxy even after moving it closer).
Move capture into HA proper so bluetooth.async_ble_device_from_address can
pick whichever known source currently has the device, instead of hardcoding
one. Protocol parsing ported verbatim from li3/van-li3-battery.
van-li3-battery is disabled on the Pi; its MQTT discovery entities were
cleared.
