The following is the first version of the Shelly 2.5 and Flood sensor plugins.
The shelly 2.5 can work in two different modes, relay and roller, and the plugin accesses the devices via HTTP. You need to specify the HostName and channel in the plugin settings. For the roller you can open, close, and stop the shutter. You can also set a specific percentage by using the slider. Finally, when the shutter is opened or closed you can orient the slats (you can use different times for opening or closing the slats to orient the venetian shutter inside the plugin).
To access the Shelly Flood sensor data, you need to generate an Authorization Cloud Key in the App under “User Settings/Security” to access the cloud data, because the sensor only wakes up from time to time under specific environment conditions. The interesting thing about this sensor is that you can use it in rain mode to make the shutter close automatically when it detects rain.
You are welcome to make this plugin better, but Bill will make a native plugin in the near future and you might prefer to wait a little bit.
