New Tuya Zigbee Product

Most of the Tuya switches should work using HE inbuilt Generic Zigbee Multi-Endpoint Switch driver.
However, some of the Tuya devices will require a Tuya-specific driver in order to control individually each channel. You can try this driver.

After installing the community driver, it is obligatory that you pair the switch again to HE. Simply switching drivers will not work, re-pairing is a must.

If this driver does not work with your device by any reason, please post the device model and manufacturer ( from the device web page 'Data' section).
