Thanks for the PR! Please add a beta label to the thermostat tile mentions so users are aware this is only available in the beta. Feature are first part of the apps beta cycle before moving to a prod release. You may refer to a previous PR for the beta label format.

Okay! how do I add a beta label?

Okay! how do I add a beta label?

you add <span class='beta'>BETA</span> on the bullet point line item and also under the header for the tile description

So with the latest change all the text is now in red. The purpose of the beta tag was actually to just show the words "BETA" in red so users understand the next sentence/section is for the beta :) You can use the exact format above in the 2 places so it can say beta before the text.

Thanks for the suggestions @dshokouhi, kinda forgot about the documentation 😅
