Light control app

home assisant integration

There are at least 3 apps with the same light control

Icon	Name	package
	GM Smart Light	com.hm.simpleble
	Le Smart Light	cn.lelight.smart.lzg
	Le+ Pro (simple ble mode)	com.lelight.pro

If your lamp works with any of the above apps, you can use this app too

Algorithm decompiled from Android app GM Smart Light v0.0.3download link

You need to find Current ID (mode) in app settings and copy it to MAC in app.py

Example:

from ble_light.connector import App
from ble_light.encoder import Commands
from ble_light.connector_bluezero import BluezeroBackend

app = App("D6FFFFFC", BluezeroBackend())
app.send(Commands.turn_on())  # Turn on light
app.send(Commands.turn_off())  # turn off light
app.send(Commands.night())  # night mode
app.send(Commands.all_light())  # all light mode
app.send(Commands.bright(1000))  # brightness 0-1000
app.send(Commands.temp(3000))  # temperature 3000-6400

How does it work?

Lamp accepts commands by listening ble advertisement packets.

Commands must be sent as manufacturer data (0xFF ble type) - two first bytes are manufacturer id and other bytes is command data.

Commands sending twice and then twice as a second message

Message contains from:

device id (called MAC in app)
group id
command and command data
message number
checksum
additional random data

Requirements:

linux OS with blueZ
for bless backend
- dbus-next
- bless
for bluezero backend
- python-dbus
- bluezero
- a lot of system libs like in ./Dockerfile

Tested with provided Dockerfile on Debian 11 host with blueZ 5.55
