[Support] Shelly 2.5 with roller shutter
**Describe your problem**
The device is appearing within Homekit But impossible to command it. 

**Describe what you have tried so far**
When I declare my RollerShutter as a light in Shelly, then I have two (On/Off) button in Homekit and with those I'm able to command the store. Impossible to control the store when I'm in a RollerShutter mode ?

**Environment:**
 - Shelly device(s): Shelly 2.5
 - Plugin version: 0.18.0
 - Device running homebridge: QNAP TS-453D NAS
