Generic Gen2+ (Plus/Pro/Mini) driver can be found here Shelly Device Handlers for Hubitat - #555 by BrunoVoeten
It includes experimental support of the Shelly Add-on module (all inputs and sensors except voltage metering)
You will need to import/install the driver to you system.
Then you need to create virtual device and assign the driver to it.
Next step is to set Shelly IP in the device driver properties page.
After setting IP press 'Configure' button on the same page (the driver will issue query to get available device components and spawn child devices accordingly)
These steps are valid for any custom/community wi-fi driver.
If you have any difficulties or problems, you may describe your case in more details to get more precise answers)
