@botany112 - How did you add the blind to the dongle? Was your solution to buy a Tuya hub or did you get it working directly with a CC2521?
The instructions tell us to put the motor into pairing mode and then press UP on the App, which presumably sends UP though zigbee that gets bridget to an RF UP signal.
How did you get the dongle to send an RF UP signal?
I am using zha currently and cannot see a way to send an UP. Here is my original post.
