Treatlife fan and light combo missing light in homebridge

[oceanapplications]

I added a Treatlife fan and light combo switch, it shows model number ea88zei7auxu48s6 in homebridge. The fan control shows up and works fine but the light control is missing. The light control is working fine in the Tuya app.

All my plugins are fully up to date. Where should I start for debugging this thing? I've tried deleting the cached accessory but it comes back again with only the fan.

Not seeing anything interesting in the log file other than [03/06/2023, 16:59:23] [TuyaPlatform] [Ceiling Fan Dimmer Switch] Device is offline, skip send command.

I've had a very similar treatlife fan and light combo switch working fine for more than a year. This new one is externally the same but appears to have some functional difference.

The API response for the new switch has
"status": [ { "code": "switch_fan", "value": false }, { "code": "bright_value", "value": 1000 }, { "code": "countdown_fan", "value": 0 } ],

But the old one has

"status": [ { "code": "switch", "value": false }, { "code": "fan_speed", "value": "1" }, { "code": "light", "value": false }, { "code": "bright_value", "value": 1000 } ],

In the Tuya device debugging page, the new switch standard instructions match the json in my last comment. It also doesn't have any instructions for light control.

I switched it to DP mode then sending the same instructions for this switch as my old switch works.

[ { "code": "switch", "value": false }, { "code": "fan_speed", "value": "1" }, { "code": "light", "value": true }, { "code": "bright_value", "value": 1000 } ]

I removed the cached accessory in homebridge, the new one created has both switches working properly.
