Hi there! I just ended setting up my fibaro roller shutter controllers on my shutters, they work just fine individually.
I have a double momentary switch next to house main door, and I’d like to use it to open/close all shutters with one press. So I bought a FGS-222 and wired it with my momentary switch (button up and button down). No load attached to it, as I need it only to understand button pressing and start opening/closing shutters.
I just can’t understand how to setup it in HA to control shutters by pressing up/down buttons… any suggestions?
Thank you 
proper scene options are available on the FGS-223
on the FGS-222 you could work your way around with using the state change on the built in relay as a trigger
