it’s not too difficult, if you have a computer that’s always on. for me downloading github desktop and cloning the repo and changing the local ip from the github desktop app menus command line took the longest, maybe 15 min since I’m slow and never done it before.
the rest is ur standard go to the IDE, device handlers, settings, add repo. then update from repo, check check, smart apps update from repo check check update. open ST app, marketplace, smart apps, my apps, web cast, enter the ip:port then discover devices, click on one discovered, check check, save. bam u have speakers in all the smartthings apps.
