So I had my harmony connect connected ok… but I changed the naming of some of my harmony routines in the harmony app which did not seem to filter through to the smart things devices.
I removed the harmony connect smart app and then added it back in, now it wont discover the harmony hub, tried rebooting both harmony and smart things hubs…
Strange question but is your Harmony hub and Smart Things hub on the same network? (Same wireless SSID too?)
Also make sure you don’t have something like Client Isolation turned on as that will stop one device talking to another - check your router that you can see both devices (they should both have an IP address)
Yes and yes for me. My integrations are still actually working, but from either end I cannot re-authorise to add more devices or activities. (Personally am using this in the UK, so eu.graph…)
