Hello @daath,
many thanks for the good news and information:).
For me the official SmartThings Drivers (Beta) (Zigbee Window Treatment) does not work. I can select it as an available drivers, however, none of the commands are working.
But I have just realized, that edge-driver from @veonua works (channel invitation in his Aqara related thread, also see other discussion about E1 devices)
It’s not perfect (yet), in my case the status of the curtain driver is not updated in the App, if i change it using the buttons on the motor itself). Also, it seems the battery status is not reported (maybe I just need to wait). But accepts all commands, and that’s important:).
