Please read TuyaMCU article to understand the terminology and configuration process.
There are a few different looking devices using the same PCB marked GD-HDFW05-v1.0 so this process should work on those.
dpID 1 device power: 0 = off / 1 = on
dpID 11 led power: 0 = off / 1 = on
dpID 12 error notification: 0 = ok / 1 = error
dpID 13 countdown mode options: 0 = off / 1 = 1hr / 2 = 3hr not needed with Tasmota
dpID 14 countdown status: reports value of 0…360 minutes not needed with Tasmota
dpID 103 mist strength: 0 = low / 1 = high
dpID 108 led color: 14 char value in hex (can define only RGB and send HSV value as max:
dpID 110 led mode: 0 = rgb_cycle / 1 = color / 2 = white
dpID 111 led dimmer color and white mode only it is important to define ‘DimmerRange 1,255’

What you get
- Relay1 turns the diffuser on or off in stored mist strength mode, turns led on or off in stored mode and serves as device power status
- Relay2 turns light on or off and serves as light power status.
- Relay3 mist strength status and control using
- Relay4 is used for error status (ON = error), no control
- Relay5 is used for light mode status (0 = rgb_cycle, 1 = color), no control
Label webUI buttons:
Backlog WebButton1 Power; WebButton2 Light; WebButton3 Mist; WebButton4 Error; WebButton5 Light Mode
Color can be changed using
TuyaSend3 108,RRGGBB64646464 (RR, GG and BB are hex value) only in color mode.
Dimming works using slider and
Dimmer command but only when in color mode, in rgb_cycle there are no brightness controls.
Long press on device’s power button initiates Tasmota’s Wi-Fi config
Home Assistant configuration
This implementation is suited to specific needs and does not incorporate all features of the device, mostly to avoid weird situations and wrong states being reported.
Fan is the diffuser. Oscillation switch is used to toggle between rgb_cycle (oscillation on) and color (oscillation off).
Light component is the device’s RGB light but only when its in color mode, when in rgb_cycle mode light state in HA is off since you cannot control anything anyway.
Binary sensor uses the dpId 12 to show when the diffuser is out of water.
