Tuya based water timer

Hardware
1

I have the orange coloured Diivoo water timer with 2 valves. When I add it to Tuya integration, there is only one switch which controls the left valve.
I looked at Tuya developer link and added the device to it and there is only one switch, how does the app control both valves ?

Code from switch.py

    # Smart Water Timer
    "sfkzq": (
        SwitchEntityDescription(
            key=DPCode.SWITCH,
            translation_key="switch",

I was able to make it work. Steps:

  1. create an account on https://platform.tuya.com
  2. Create a new project
  3. Add the device using Devices->link app account (use Smartlife app username/password)
  4. Go to device debugging and there is a link at the top [product details], click on that
  5. In the next screen switch " Select Control Instruction Mode" to DP Instruction and save
  6. in HA got HACS and install this GitHub - lasry1/home-assistant-tuya-custom: ggq added and do not restart yet
  7. Open the custom_components/tuya/switch.py on you HA (you can use the File editor)
  8. Look for sfkaq
  9. Remove that section and replace it with
    # Smart Water Timer
    "sfkzq": (
        SwitchEntityDescription(
            key=DPCode.SWITCH,
            name="Switch",
            icon="mdi:sprinkler-variant",
        ),
        SwitchEntityDescription(
            key=DPCode.SWITCH_2,
            name="Switch_2",
            icon="mdi:sprinkler-variant",
        ),        
    ),
  1. Save the file and restart HA
  2. Go to settings devices and services and Add Tuya custom integration and configure it as you would normally

You can use my custom_component after doing steps 1-5

Thanks for the info.

I’m trying to use GitHub - lasry1/home-assistant-tuya-custom: ggq added just for the 1 switch controller Diivoo WT-03, which seems to be a sfkzq water timer (based on the Tuya debug data).

When I restarted HA I can see the old integration entry failed to bet setup, so I created a new one. When I did that I see the device, but the switch is not controllable, and the diagnostic valuse are all still unavailable.

where there any other suggestions involved it getting this to work?

You need to use my repo (previous post) and follow the instructions in that repo to switch the device instructions.
