I’ve never used the Tuya integration or their zigbee hub. You can still try the Event tool. If you use * as your event type to listen for, it will show all events. You would then need to sort through them to see if there are any related to your button presses.
Also, please follow Forum Guidline #6 and change the topic category of this thread to Zigbee or Third Party Integrations… Installation is not the proper tag.
