When I want to open/close a cover in an automation and in an action select Device, then a device with a cover I expect an easy way to open/close (like there is a Turn On/Off for lights).
The way I can do it through Device actions is to set a position which does get the job done, but I need mentally switch from open/close to position, tick a checkbox (why? there is only one option) and figure out if 0% or 100% is open or closed (I always forget since HA is different from the native app)
Just to show, no option for open/close 
(this is a Somfy cover exposed through the Overkiz integration btw)
I know I can do it the other way around through the “Call service” option, then select “Cover: Open” and the device, but when I have an automation in mind it is like “I want this device to do that”, not the other way around if that makes sense.
