I’ve just upgraded to the latest HA and have noticed that some of my hidden sensors are showing up on the front end.
Nothing has changed in customizations and some old/raw sensors have appeared in the front end under groups that they are in. These sensors don’t need the raw data shown in the frontend as I use template sensors to reference them and get nicer output.
In my customizations I have:
sensor.ldr:
friendly_name: Raw LDR
hidden: true
But it still shows up in the front end.
