I renamed one of my activities in my Logitech Harmony hub and when I try to reauthenticate in the Connect app within Smartthings classic iOS app, it doesn’t appear to login properly and pull all of my activities. If I put the right or wrong credentials in and click Next it allows me to tk through but never pulls in the right activities into “Things”.
Screenshot below…
I removed all of Harmony devices and activities and reinstalled the Harmony(Connect) app and it still doesn’t connect. This leads me to believe it’s a system wide issue. Support hasn’t responded to my ticket in 5 days. Anyone else having these issues???
It turns out I fixed it. I must have had a “ghost” or corrupt hub in my Harmony setup. I went into Harmony and renamed all of my hubs and then it fixed it.
I will try that. I’ve been ignoring the error message from Alexa the past couple of days and doing the work myself (gasp!).
