The following is the link for Edge Drivers for Shelly Gen 1 & 2 devices. I don’t know of any drivers for Gen 3. The developer who wrote these is no longer active in this forum.
March 2024 Update
FYI, support for GEN3 devices should be ready in April.
September 2023 EDIT:
So new readers don’t have to read through all the posts to get caught up…
I have developed Edge drivers that support many of the Shelly GEN1 and GEN2 devices. This allows you to create automations that don’t rely on a cloud connection since Edge drivers are locally executed on your hub. Note that a SmartThings hub is required for these drivers.
For those with battery-powered Shelly Gen1 devices, I have a third driver that requires the use of MQTT. See this post for more information.
If you need other devices supported that are not listed below, just ask. I can add support for them, but I will be dependent on you to test.
