I have been integrating Shelly 1 relays into Smartthings.
The 1st relay appeared as a new device as soon as a linked Smartthings to the Shelly Cloud.
The 2nd device didn't appear.
I deleted the 1st device and now no devices appear.
Both devices are fully functional through the Shelly App.
Is this a known issue with Smartthings or Shelly Cloud?
