Problems with Honeywell Evohome HGI80 integration

Hi!

So I am setting up my HA system currently and most things have gone well, including the initial setup of the Ramses HACS based integration for Evohome, for which I use my existing HGI80. I kept the install and config very minimal because I didn’t fully understand the concepts around whitelisting devices etc and the docs while good didn’t help me understand how to find the right info and where to put it.

Fast forward to the last couple of days and the system is no longer displaying information at all and I am not seeing this error message

(in case it doesnt load, it reads error during setup of component ramses_cc)

What I would like to do is firstly completely remove the integration and then reinstall it from scratch and then create the necessary config in the configuration.yaml so that only the active devices are known and everything else can be ignored.

I am struggling with both of these points, and would really appreciate some clear guidance on how to do both.

Really appreciate any help given.
