Red switch install few questions

In hubitat, there is a community app called « Hubitat Package Manager » (HPM). My recommendation would be to install that app first. Instructions can be found in the Hubitat Community (community.hubitat.com) by searching for its name.

Once this is installed, you can search for « Inovelli » and then chose the driver(s) you need.

The other option would be to get the driver you need from here:

Then in Hubitat, you will need to install it (there are a couple of steps required) and the community will be happy to help if you get stuck.

I would pair it as soon as it is installed, but either option works.
