For anyone new to unRAID/Docker (like me), this means go into the Docker Settings in unRAID and edit your Homebridge GUI docker container. Change the 'Plugins' option from "homebridge-pilight homebridge-info homebridge-wemo" to "homebridge-pilight homebridge-info".
When I restarted after the above, I was getting a plugin error with SmartThings (Error: The requested platform 'homebridge-smartthings.SmartThings' was not registered by any plugin.). I was able to resolve it by updating Homebridge (sudo npm install homebridge homebridge-smartthings -g) and restarting the docker.
