When I set-up an item I can pick a categrory. In the list I have light as well as lightbulb.
What is the difference and when should I pick which?
One difference I have noticed is that those items (points) which have “light”, will show a grey lightbulb in the UI when the light is off while the items with “lightbulb” always show a yellow lightbulb - no matter wheter they are on or off.
