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.”
Afraid only solution was to delete my Samsung account, recreate the account, and the re-register the HUB. After all that trouble I could add the switches
