To deactivate the comfort zone, touch the blue icon at the bottom right of the detail screen of your Filo Tag. Alternatively, go to the settings menu by clicking the three dots at the top right and then click on "Set Comfort zone".

You can choose to deactivate it or put it on stand-by momentarily, or you can also decide how long you want it to remain deactivated: 1, 4, 8 hours or ALWAYS.
