I have just received my Aqara Curtain Motor and I am happy to report that the device automatically pairs with Smartthings although with a generic device handler (i.e., no need to search for a catchall). You just need plug the motor to electric power, click ADD THING on the APP and press the motor button for 5 seconds until the blue light starts flashing rapidly. I replaced the default device handler with the bspranger’s Xiaomi Outlet (https://github.com/bspranger/Xiaomi) and the Aqara Curtain Motor works perfectly! Unfortunately I have not received yet the curtain rails, once I have them I will draft a more specific device handler.
