Z wave thermostat (heatit/mutireg) status feedback / energy

Yesterday I decided to try firmware 1.92 on one of my thermostats. to avoid using the above automation to know if the thermostat is heating or not. Also I’m hoping to get this information in to the thermostat “card” (green sections showing the thermostat is heating) simila to a general thermistat, like this:
Capture
I already knew there are some challenges when it comes to compability with opezwave and some have reported strange temperature readings. Upgrade went fine, however it seems the xml file needs updating as entities added dont make any sense. I understand that that means remove the node from zwave network, stop home assistant, modify xml file, start home assistant and re include the node.
My question is, which xml file to use, perhaps this? And how to implement it?

Thanks!
