bluetooth_lights_controller

A modification of kabyru's modification of Christian Volkmann's govee_btled wrapper, fixing a bug with multiple lights and adding support for the Govee H6005 bulb (see Usage below).

I have tested and confirmed this to work with the H6001 and H6005 LED Light Bulbs, and based on this it should also work with the H6127 LED Strip Lights and maybe other Govee/Minger lights. I have only confirmed it to work on Mac, but it should also work on other platforms.

There is a known issue with the H6005 where you can't change the white color temperature - the temperature parameter for set_color_of_light_white is ignored. Presumably it requires you to encode it differently; I will look into it soon.

Installation

Use pip to install:

pip install -U git+https://github.com/jonahclarsen/bluetooth_lights_controller

Usage

from bluetooth_lights_controller import BluetoothLED
import asyncio

lights = {  # Replace these with your LED's MAC address (see below for instructions to find)
    "bedroom": 'XX:XX:XX:XX:XX:XX',
    "lamp": 'XX:XX:XX:XX:XX:XX',
    "h6005-kitchen": 'XX:XX:XX:XX:XX:XX', # For the Govee H6005 we need to include "h6005" in the name here
    }


async def main():
    for _ in range(2): # For some reason, setting a color sometimes fails (maybe 1 in 50 times). You could then just re-run it manually, but I like doing every command twice so it basically never fails
        await set_color_of_all_lights_white(lights, -.45, 1)  # Day
        await set_color_of_all_lights(lights, 'orangered', 0.5)  # Evening
        await set_color_of_all_lights_white(lights, 0, 0)  # Night (off)
        await set_color_of_light(lights["lamp"], 'blue', 1, is_h6005=True)
        await set_color_of_light_white(lights["h6005-kitchen"], 0.5, 1, is_h6005=True)

loop = asyncio.get_event_loop()
try:
    loop.run_until_complete(main())
finally:
    loop.close()

Also included...

On the root of the repo, there are two additional Python scripts:

• govee_payload_generator.py generates the 20 bytes long payload that would be sent to the bulb via BLE. Useful for troubleshooting.
• search_btle.py returns a dict of MAC Addresses and Device Names of the devices of interest given a search phrase. Useful to integrate into programs where you do not know the MAC Address of the BLE devices you want to interact with (e.g. a room full of Govee bulbs...) To use this, simply call print(search_btle("minger")) or print(search_btle("600")) (my Govee H6005 showed up as 'ihoment_H6005_664B').

Reverse Engineering of H6001 BLE Packets

Have a look here for how the BLE packets that control the state of the LED bulb were reverse engineered. There is also some information on chvolkmann's original repo, which I used to figure out H6005 support.
