Have SmartThings HUB and trying to add Leviton Decora WiFi switches & dimmers.
Have an abundance of the switches, all working fine in the Leviton app and via IFTTT.
When I try to add them in the SmartThings (Android) app I get the following message:
“We’re having trouble connecting. Check your network connection and try again.”
If I go to the web interface (graph…api.smartthings.com) the log says:
error java.lang.RuntimeException: Unexpected status code 400 from global /clients/null with status text Bad Request @line 357 (deviceDiscoveryPage)
Tried to find a way to open a support ticket on samsung.com but that was pretty hopeless.
So back to asking the community. Or maybe someone can guide me as to how to open a support ticket.
