lastUpdate on switch selector

[roblom]

Is it possible to check how long a switch selector was on a certain level?
I have a switch selector 10, 20, 30, 40 and want to use the .lastUpdate.minutesAgo but not on the swicht but on the level of this switch, so count how long level 40 was actif for example.

There are scripts available that can count how long a switch is in On status, eg for calculating run time of an engine. Those should be able to rewrite to selector switch. Example: viewtopic.php?t=23713

Thank you for your reply, I used another trigger which was easier than write some code to count. The link you supplied is still useful so I saved it.
