MINI as switch +plus sensor status
* **Please explain your feature request in a one or two sentences.**
I want to be able to see my Sonoff mini as a switch in the Home App and also have the state as a separate sensor type in the Home App.


* **Is your feature request related to a problem? Please describe.**
Currently, the plugin allows the MINI to be used as a sensor of various types. However, the "switch" functionality is lost. So I need to show the switch plus have the state sent to the Home App as a virtual sensor. Sensor setups allow Apple Home push notifications.


* **Any particular eWeLink devices that this relates to?**
MINI and other single-channel devices.


* **Anything else?**
Not yet.
