Aoycocr Q9WM A21 10W 900lm RGBW Bulb
Model reference: 2AKBP-Q9
Tuya-Convert might not be possible for this device if the manufacturer started using newest Tuya firmware since this template was published. Instead you can likely serial flash Tasmota without soldering with a flashing jig, if the device is easily opened.
By default, bulb does not allow both the RGB and W channels to be active at the same time.
SetOption37 128 in the console allows for that to happen.
