The Tuya Cloud app needs a bit of time and good reading, to set up properly. But that is a one off operation.
I carefully followed the great instructions at post #1 of the Tuya Cloud topic, and it worked right away.
And when it works, you can operate the curtain tracks as any other device in Homey, or use the two excellent workarounds, which are also pointed at in the Tuya Cloud topic.
