Hi, I searched the community for Somfy threads and this one has some recent activity. I recently switched over to Hubitat from SmartThings and has been using GitHub - bendews/smartthings-somfy-mylink: SmartThings Device Handler for Somfy MyLink with my SmartThings to have it talk via LAN to a Somfy MyLink wifi device. The MyLink device sends the RTS codes to the Somfy shades, see Somfy's myLink: Home automation for all your window coverings.
The SmartThings code needed some modifications to work on Hubitat and I've made them in the "hubitat" branch of my own fork here: GitHub - scelfo/smartthings-somfy-mylink at hubitat.
I sent the original author a pull request but he isn't using SmartThings anymore so doesn't want to maintain a branch and suggested I fork and take over. Anyone on this thread have a Somfy MyLink and want to help test my fork of the project? My fork would be Hubitat specific so I'd cut it down even further from its current state (i.e. remove SmartThings app icons) and write a Hubitat specific set of setup instructions.
