Oops, forgot to include the link to the css fix, included it now (and also here)
It is not possible to exclude devices from the device overview if they have any of the capabilities that are monitored (alarm_contact, alarm_motion, alarm_tamper, alarm_vibration).
Also, only devices that have any of those capabilities should be shown, I can’t see how light bulbs and/or temperature sensors would show. Can you provide a screenshot where you see them?
