Every device has a manufacturer and product/device ID. If the device is added to Homey, also as unknown or as a wrong device, these IDs can be found in the advanced settings of the device or in Developer Tools → Devices:
If these IDs aren’t listed in the first post of the [APP][Pro] Tuya Zigbee App topic, then it’s not supported by the Tuya Zigbee App.
But in the first post of the Tuya Zigbee App is explained, how to request a device.
