Homebridge Uk integration help

Hi There, I am really new to this and to general community forums in general. I have been trying to get Homebridge working with Smartthings using the tutorial from http://www.automatedhome.co.uk/apple/smartthings-raspberry-pi-homebridge-siri-homekit-controlled-smart-home.html

It looks like the command “sudo npm install -g homebridge-legacy-plugins” no longer works and im really stuck on how to continue.

I have gotten my Nest working with Homebridge and absolutely love the functionality and being able to use google assistant, Alexa and Siri.

Any help would be much appreciated.
