TRVZB features in Home Assistant

Apologies straight off for what is probably a really newbie question:

I have a number of TRVZBs. When I try and configure them into dashboards or automations in home assistant, some of them show hvac_modes of ‘off’ and heat, some only show ‘off’.

Wheras they look the same to me when I look at the device info they are obviously being recognised differently somewhere with HAs db and I don’t have the experience to know where to look.

Could someone please advise and I’ll delete thistopic to stop clogging up the forum with dumb questions

OK, worked out how features work now
