I have two sensors as shown in the image below. I am able to use the upper sensor (sensor.gasverbrauch) but I am not able to select the lower sensor (sensor.gasverbrauch_haus) as a source for the energy dashboard Gas usage tracking. As you can see in the image they are exactly the same apart from the name, why is one of them not showing up when I want to track my gas usage?
Maybe you need to wait for a few hours before long-term statistics are generated for your sensor. The sensor shouldn’t be unavailable during that time. After that, it should show up in the menu.
