I have 3 harmony hubs. They were all working fine…visible within SmartThings. Suddenly, two of them dropped out. I have tried unplugging and re-plugging the harmony hubs. I have tried rebooting the ST hub. I also tried signing out of and back into ST from within Harmony.
So, now all the activities that are tied to those 2 hubs are not accessible from my ST rules.
Any ideas? Workarounds?
