You probably want to post this in the main thread for whichever homebridge plugin you're using. Doesn't appear to be the one linked to by @ogiewon because it uses MakerAPI and not a specialized app.

I got a successful config saved in makerAPI and that still doesn't work29/01/2022, 20:55:49] [Hubitat-MakerAPI] Initializing Hubitat-MakerAPI platform...

Please use the thread linked to by @ogiewon to follow-up.

makerAPI actually freezes up homebridge

Then you've done something incorrect. Again, I would suggest following up on the thread @ogiewon linked to.

I can't work it out
I am using this and it says its ok but it just don't work

I followed the link provided and I worked out how to copy and paste now to make it easier but it still freezes when I try

Well in my adventure last night I seem to have broken it all, nothing is working at the moment I think I will maybe reset and try again
