Simple way to trigger an 24h timeline?

Without seeing your exact config I am cannot be sure on exactly how this is setup but here is where I would start.

First your base timeline, if this is just a static look then I would just have a timeline that starts on startup but set its priority to Lowest.
This will mean this timeline can be stomped on by other timelines at higher priorities but when they release it will still be playing back in the background.

Your 1 Day effect timeliene can run at Normal Priority and as above will stomp on the normal timeline but when its released it will go back to the base.

For your real time triggers that are setting levels of the fixtures I would make these be set master intensity actions so they just dim up and down the master meaning the base timeline again is still running underneath.

To stop the master intensity triggers from running when using your special 1 day timeline then I would add a condition of if timeline on stage (negate) to these triggers so they wont fire if the special 1 day timeline is playing back but will when it isn't running

Hope this makes sense.

If you have quite a lot of 1 day special timelines, so that you don’t have to add them to the conditions each time of excluding dimmer control: patch a single channel to a sAcn universe and then add that channel at full to each special timeline. Then in your condition to exclude dimmer control, if that channel is at full, then don’t do the trigger. 

I was going to suggest logic that looks for a looping dummy timeline that triggers with a flag or when one of the special timelines starts to do something similar, but I like your way better.
