GEN2 DRIVER UPDATE NOTICE
I have pushed out an update to the Shelly Gen2 Device Driver V1.3, which is now driver Version 2023-04-13T15:15:51.357935579.
This update includes temperature (ds18b20) and digital/analog input add-on support for the Plus1 and Plus1PM devices. Add-ons are detected during device discovery, so no manual device Settings are needed. If you connect one of these add-ons for an existing SmartThings device, you’ll need to delete the existing device and get it recreated through an Add device / Scan for nearby devices.
Thanks go out to @Bruno_Almeida and @tgift00 for testing the driver for me.
Please note that if add-on support is needed for the humidity or voltmeter attachments, or add-on support is needed for other device types (i.e. Plus2PM, PlusI4) I can add that upon request.
One other update item is that the Creator device will no longer get created for initial driver installations, and the IP address in device Settings should be ignored (it has already been removed for some devices). There is no manual creation of GEN2 devices - they are discovered and created automatically. With this driver update, you can delete any existing Creator device you may already have and it will not get re-created the next time you scan for devices.
