This works throug setting up a developer account with Tuya. Works like a charm, but i lost the how to instructions or better the link to the website that exolaines the process. In case something goes wrong (not that it has in the last 2 years) I would like to know where to find it again. Can anyone help me out?
I would still guess you have a Zigbee hub (Tuya) somewhere as if not, with what is the Zigbee device communicating to execute it´s actions.
Maybe you refer to this? Tuya - Home Assistant
