Using BLE gateway with BLE Lamps

[Ardumine]

I bought a "Wireless Bluetooth gateway" (of type wg2) with 2 BLE lamps (of type "dj"), "C1206_P0_B1_LT01". They are bluetooth mesh on what I understand. I can connect via the SmartLife App and control them wth no issue. Tried adding it to the Tuya Local in Home Assistant and no success. The official Tuya componnent detected the lamp but it shows like this:

As you can see, no color controls and I can only turn on and off the lamp.
I tried with the tinytuya:

import tinytuya
import time
tinytuya.set_debug(True)

# Ble Gateway
gateway = tinytuya.Device('bfe', '192.168.1.194', local_key='REDACTED', version=3.4, persist=True) #
gateway.disabledetect = True

gateway.set_socketTimeout(1)
print(gateway.subdev_query())

The logs:

I can't get the lamp.status(), getting the error "json obj data unvalid".

Can anyone help me? Thanks!

Hi @Ardumine - Full transparency, I don't have a similar device. But, let me see if I can help. BLE gateways (wg2) don't support direct status commands like WiFi devices. When you call gateway.status() or lamp.status(), you get "json obj data unvalid" because the gateway expects all commands for sub-devices to go through the command 7/13 protocol, not command 10 (status). Hum, I think.

I would try async receive/send pattern instead of status/control methods. Here's the working approach:

import tinytuya
import time

# Setup BLE Gateway
gateway = tinytuya.Device('your_gateway_id', '192.168.1.194', 'local_key', version=3.4, persist=True)
gateway.disabledetect = True  # Required for gateways
gateway.set_socketTimeout(5)

# Setup BLE Lamps as children
lamp1 = tinytuya.BulbDevice('lamp1_dev_id', cid='lamp1_cid', parent=gateway)
lamp2 = tinytuya.BulbDevice('lamp2_dev_id', cid='lamp2_cid', parent=gateway)

# Query which sub-devices are online
online_status = gateway.subdev_query()
print("Online devices:", online_status)

# Control Pattern - use nowait=True and monitor via receive()
print("Turning lamp1 off...")
lamp1.turn_off(nowait=True)  # Send command without waiting for response

time.sleep(0.5)

# Listen for updates from gateway
data = gateway.receive()
print("Response:", data)

# Monitor loop for continuous control
print(" > Begin Monitor Loop <")
heartbeat_time = time.time() + 9

while True:
    # Send heartbeat to keep connection alive
    if time.time() >= heartbeat_time:
        payload = gateway.generate_payload(tinytuya.HEART_BEAT)
        gateway.send(payload)
        heartbeat_time = time.time() + 9
    
    # Receive updates from any sub-device
    data = gateway.receive()
    
    if data:
        print('Received:', data)
        # data['device'] will reference which child device sent the update
        if 'device' in data:
            print(f"Update from: {data['device'].id}")
    
    # Example: Toggle lamp based on state
    # if data and 'dps' in data and '1' in data['dps']:
    #     if data['dps']['1']:  # lamp is on
    #         lamp1.turn_off(nowait=True)
    #     else:
    #         lamp1.turn_on(nowait=True)
    
    time.sleep(0.1)

For setting colors on BLE Bulbs can we use the BulbDevice methods with nowait=True?

# Set color (RGB) - nowait is critical for BLE devices
lamp1.set_colour(255, 0, 0, nowait=True)  # Red
time.sleep(0.1)
data = gateway.receive()
print("Response:", data)

# Set brightness
lamp1.set_brightness_percentage(50, nowait=True)
time.sleep(0.1)
data = gateway.receive()

# Set white mode
lamp1.set_white_percentage(brightness=100, colourtemp=50, nowait=True)
time.sleep(0.1)
data = gateway.receive()

Let me know if this helps!
