[Support] Shelly 1 not discovered in Homebridge
Want to use a Shelly 1 as a switch to open garage door within HomeKit via Homebridge. Not using it as a garage door opener as there is no need for security (i.e. avoid confirmation within HomeKit). 

My environment:
- Homebridge installed on Raspi4, IP 192.168.2.4:8080 (long time running installation without issues), hardwired
- Plugin homebridge-shelly v0.18.0
- Shelly 1 (recent beta FW 20210514-065742/v1.10.5-rc1-gecc99b7), IP 192.168.2.17:80, WIFI

I can access the Shelly via http without issues. 

Settings on the Shelly 1:
- ColoT peer set to 192.168.2.4:8080 (also tried with mcast)
- Device discoverable YES 
- Authentication disabled
- other settings not of importance I guess?

Homebridge Config:
`{
            "name": "Shelly",
            "admin": {
                "enabled": true
            },
            "devices": [
                {
                    "id": "8CAAB5552E95"
                }
            ],
            "platform": "Shelly"
        }`

Rebooted the Shelly and the Homebridge several times. However, the Shelly is not being discovered. Tried with set "networkInterface": "192.168.2.17" won't work either.

Previously, I have utilized the Shelly with the Mongoose FW (https://github.com/mongoose-os-apps/shelly-homekit/wiki/Garage-Door-Opener-Settings) and utilized it as a GarageDoorOpener. This worked well. However, I wanted to open the garage door automatically once my wife and me come home and such automation required a confirmation - what I want to avoid.

Can anyone guide me through troubleshooting?
