Ok…
Sounds like you’re integrating the Shelly Devices into SmartThings using the Shelly Service (which is certainly the logical way to go). Maybe the Shelly Cloud is experiencing some issues/slowdowns. Wouldn’t hurt to reach out to Shelly to see if they are having issues.
Pease Confirm:
- Open a Shelly Device Card in SmartThings, 3-Dots Menu:
- Do you see a “Driver” option ? If so, select it and it will indicate the Edge Driver you’re using.
- If not, select Edit, then down at the bottom it will likely indicate that the device is connected through another service.
There is an alternative to using the Shelly Service: You can control the Devices directly/locally within SmartThings with an “Edge Driver”. The Shelly Cloud App continues to operate separately as before.
Here’s a link to @TAustin 's Shelly Drivers.
They work great for us and are very responsive!
