This issue just started happening 24 hours ago and I can reproduce consistently. SmartThings g3 hub integrated with latest lutron caseta hub/account. 3 devices discover. They show up in SmartThings app and work. Then either after a few seconds or after I turn a device on/off the other devices literally vanish from SmartThings. I can reaadd then and they vanish again.
Tried deleting the integrations and reconnecting. Same issues. Reboot SmartThings. Same issue.
I’m at a total loss and not seeing anyone else talk about this. HELP!
