Switch channel logic based on other switch channel

[BeanAnimal]

Quite simply -

My skimmer pump is on a switch channel.
The UV is plumbed inline with the skimmer.

I want the UV to shut off when/if the skimmer feed pump is shut off.

It would appear that there is a missing logic option "Switch Channel" as logic input.
I don't want to purchase a flow sensor for this (I don't want to clean the darn thing).

Thoughts?

How du you shout off the skimmer?

I don't currently. I know that I could setup a maintenance or similar logic to shut both off...

I was looking for more of a hard tie logic:

IF SWITCH 2 OFF (for any reason) THEN SWITCH 12 OFF
PERIOD

That way feed mode, maintenance, manual override, etc. would ALL ensure that the UV is not running.

I could also connect both to the single switch channel, but then I lose individual control and I eventually think I want the UV on a timer instead of 24/7

Also reading, I guess a flow sensor would not work either as they can't be incorporated into logic.
