I looked everywhere to try and add the temperature information to Hassio… Couldn’t find a yaml example… tons of reading on sensors and templating etc etc. Solution was simple, but somewhere there’s someone looking for the same thing. Here’s to ya!
In Hassio, click the top right sideways elipses (some call it the hamburger icon - the one with three dots), click ‘configure UI’. Click on the pencil icon next to “HOME”. Under View Configuration click on Badges. On the last blank Entity hit the down arrow and select sensor.hue_sensor_1_temperature. Your name may be similar. Hit save.
If you don’t need any stinking badges (a Blazing Saddles reference), then hit the yellow plus at the bottom right. Select “Entities” (or your preference) and then under the Entity dropdown you will find the sensor there.
I know this is simple (and large credit to the HASSIO team for making this easy!) but it was so simple I didn’t think to even try it.
Hope I save you time if your searching for it.
