Shelly Dimmer 2 isn't found in Hoobs/HK
Hi @alexryd 

following Problem:

I run Hoobs with the Shelly-Pligin on an Rasp4 4GB all with latest Firmwares.
I have several Shelly 2.5 in use and they're working well.
Now i have installed an Dimmer 2 with actual firmware and it works fine in Web-UI and Shelly-App but isn't found by Hoobs nor the Plugin
see the output from shelly describe:
![grafik](https://user-images.githubusercontent.com/73744851/97779597-5c674380-1b7f-11eb-8844-0a2c16e4b5c2.png)

The strange thing is, i have 5 shelly 2.5 and the dimmer2 installed. when i'm restarting the Raspi the log shows : "6 Accessories loaded from cache"  so in my Opinion hoobs registered the Dimmer2 ?!?
Please help me to fix this issue!

thanks a lot
