Im currently trying to find out a way that i can make a digital tag that goes from on to off and off to on every 15 minutes or so. Is there any suggestions on what the best way to do this is. I will be pairing this tag with another one in an expression to trigger a multi write tag every 15 minutes while the day is between certain times. Any suggestions help! Thanks

The toggle function and a trigger tag might be the way to go, link to the toggle function below:

I would use a trigger tag. Set the on interval to 30 minutes and set the off interval to a 15 minute (900 second) delay. Then you should have a digital which toggles 15 minutes on and 15 minutes off.

@TomE so would i link the toggle function within my trigger tag expression?

Negative, using the trigger tag does not require any custom code or expressions. The toggle function would require custom scripting so I'd suggest simply using the tag.
