TreatLife DS03 dimmer not working

[jlg89]

Describe the bug I can't get the dimming function to work from HomeKit for my TreatLife DS03 combo switches.

With useBrightness disabled, I can toggle the light on/off from HomeKit, and when on it retains whatever brightness setting was last selected on the switch itself (or in the Tuya app).

With useBrightness enabled, when I first pull up the dimmer in HomeKit, it shows the actual value (i.e. minBrightness to 1000), with the yellow slider extending off the bottom of the screen, instead of scaling to HomeKit's 0-100%.

As soon as I adjust the slider, it pops to 0-100% mode, but the only places it will "stick" are minBrightness or full on. What's odd is that the button in the main HomeKit screen shows the correct percentage (in this case 50%), but when I tap to pull up the slider it shows 500% initially.

Current config looks like this:

{
            "type": "FanLight",
            "name": "Ceiling Fan",
            "id": "<redacted>",
            "key": "<redacted>",
            "manufacturer": "TreatLife",
            "model": "Ceiling Fan Dimmer Switch DS03",
            "dpBrightness": 10,
            "useBrightness": true,
            "minBrightness": 100,
            "scaleBrightness": 1000,
            "maxSpeed": 4
}

According to tuya-cli, the dpBrightness is 10, minimum brightness is data point 105:

{
  '1': true,
  '3': '4',
  '9': true,
  '10': 1000,
  '105': 100,
  '106': 'mode1',
  '108': 1
}

The log shows odd "unreachable by faulting Service" errors. But the fan portion works, so I'm guessing that isn't a big deal.
