I’ve been running HA for a few years now and a couple of weeks ago I finally decided to wade into my own Lovelace layout. I was happy and had single buttons for controlling all of the lights. Following the latest updates those buttons stopped working. It appears that I can no longer add a single button to control the entire area. I did not notice that in the release notes. Am I missing something, or is there a new way to accomplish this?
Thank you for the reply, however I believe we are looking in two different places, as that still works on “entities” cards. What I was using before was a “Button Card” with the entity set to the area. That allowed me to save space while still controlling all of the lights at the same time for power, color, etc.
