Climate color based change on hvac_action

[SylvainDx]

Hello,

I'm not sure this is an issue for this git or another, i'm sorry if i'm at the wrong place.

So lately there was a change on marvinroger/hass-addon-tiko#25

Basicly they change the how you read state

before that a climate entity was heat if heating and off the rest of the time no matter the prestets.
Now it's only off when offline.

and a new attribute hvac_action as been created with 'off' 'idle' or 'heating' value.

at this point I lost track with what i did in the past and my brain won't go back online for now ... :(

I colored my button with this stlyling option :
.bubble-icon {
color: ${hass.states['climate.salon_heating'].state === 'heat' ? 'orange' : 'white'} !important;
}

what can i do to grab the new attribute ?

Thank you so much for your help !
by the way is this change for all kind of climate or is it just a "tiko" special ?
