[RELEASE] Homebridge Hubitat v2.0

Noob help please!

Disclaimer...I dont know what I'm doing other than blindly (trying to) follow the installation instructions. Basically I need an idiots guide.

What I've done:
Installed Homebridge on RPi
Installed Homebridge V2 on HE
Installed Homebridge-Hubitat-tonesto7 plugin on Homebridge (using Homebridge UI)
Populated the config settings in Homebridge using the info from Homebridge app in HE.
Added Homebridge to Homekit. I see Homebridge in Homekit.

I've added 1 device (a light) to the HE app to test....expecting to see it in Homekit. It's not there.

Homebridge on the RPi reports it is up to date, running and the plugins are up to date.
I see there's a config file (which means nothing to me!)
I see nothing under the Accessories tab (Other than 'Default Room/Drag Here")

What's next? -how do I get to see my device in Homekit/How do I troubleshoot?

Thanks in advance.

EDIT: HomeKit is telling me there is no response from Homebridge...
EDIT: IG note previous edit...that wasn’t the case at all. A reboot of the Rpiand my light is now visible in HomeKit. So have tried adding more lights to Homebridge...but same again...they don’t appear in HomeKit...even after restarting Homebridge (and a reboot of rpi). Should devices appear in HomeKit shortly after adding them in the Homebridge Hubitat app?
EDIT: Fixed. Uninstalled Homebridge HE app and re-installed
