Manage Govee DreamView T1 (H6199) BLE devices

Govee DreamView T1 (H6199) Ble client

This is a simple python client to control the Govee DreamView T1 (H6199) via BLE.

Limitations

The client was tested on a device with 1.10.04 / 3.02.01 FW/HW versions.

Getting current mode would not return currently set color of a static mode and wouldn't distinguish specific music modes and their parameters. The former is caused by device responding with all zeroes, and the latter can be fixed in the future.

There is no support for setting colors for specific segments, nor controling the brightness for individual segments.

Usage

The client uses bleak library and relies on it's BleakClient instance. Client supports the following actions (from govee_h6199_ble.commands package):

• Get state
  • power
  • fw version
  • hw version
  • mac address
  • brightness
  • current mode
• Turn on/off
• Set brightness
• Set Static color mode
• Set Music color mode
  • Energic mode
  • Rythm mode
  • Spectrum mode
  • Rolling mode
• Set Video color mode
  • Movie mode
  • Game mode

More information can be found by inspecting the govee_h6199_ble.commands package.

Example

from bleak import BleakClient, BleakScanner
from govee_h6199_ble import GoveeH6199, GetFirmwareVersion, PowerOn, PowerOff

if __name__ == '__main__':
    # scan and find first usable device
    devices = await BleakScanner.discover()
    named_devices = (device for device in devices if device.name)
    h6199_devices = (
        device for device in named_devices
        if device.name.startswith("Govee_H6199")
    )

    if device := next(h6199_devices, None):
        # connect
        async with BleakClient(first_device) as client:
            async with connected(client) as h6199:
                power = await device.send_command(GetPowerState())
                if power:
                    print("power on")

                    # get firmware version
                    fw_version = await device.send_command(GetFirmwareVersion())
                    print(fw_version)

                    # turn off
                    await device.send_command(PowerOff())
                else:

                    # turn on
                    await device.send_command(PowerOn())

The chain of commands can be sent using send_commands but in this mode you will not receive any responses.

You can also run raw commands using:

async def command_with_reply(
    self,
    cmd: int,
    group: int,
    payload: list[int] | None = None,
    timeout=5.0,
) -> bytes:...

and inspect responses manually. Be aware, if the command is not implemented in the device this call command will raise asyncio.TimeoutError, since response will not be received.
