Hi! I’ve added 3 aqara e1 roller shades, all without any issues. Big thanks for the update! 
Don’t know if i should post the following question in the group thread but since there’s most likely a few in this thread that has been waiting and now adding the E1 roller shade I’ll try here first. I tried making a group with these 3 roller shades using group but it couldn’t find any devices with “shade ability”. Has any one else tried to group several e1 roller shades and has any tips on how to do it, with or any other way?
