Sensibo Elements - Displaying Temperature on a Card in Home Assistant

I have a Sensibo Elements connected to Home Assistant (2025.11.1), and I am unable to add a card to display temperature. I have been able to add Bedroom AQI and TVOC cards, but not a standalone card showing current temperature.

I read this thread and followed the instructions, but was not able to achieve the same results:

The “Bedroom Temperature” sensor was not available to select in a sensor card after making the edits suggested.

Any support would be appreciated!

Did you create the template sensors out of your climate entity as described in the thread you mention?
What are their value?
