I’ve got the curtain module working with my Google Home device. There is a YouTube video I posted showing exactly what I did and what components I purchased.
The device shows up as a switch. The command is on for open and off for close. I’d really like to change this to open-close respectively. Perhaps one day I will figure this out.
