### What issue do you have? Please be as thorough and explicit as possible.

After the Meross plug-in upgrade to v6, I reconfigured my devices by enabling cloud mode instead of local mode. Home app is now showing that updates are available for my devices (5) and upon clicking the update link, home app opens the Meross app. However, there are no firmware updates available in Meross. I simply can’t get the updates available message to go away. The home all also displays a badge with 5 in it. 

### Details of your setup.
* Do you use Homebridge (with config-ui?) or HOOBS?
