Hello,

I am having an issue- I am trying to send notifications for machines being down and then a notification when it has been cleared.

For some reason I can only get the initial Down notification to work. Currently I have the tag setup with an alarm that is delayed by 2 hours to start a notification pipeline. But I tried to add a branch off of the pipeline (below) for isactive to send a seperate notification- that part never works. What am I missing?

I think you need a feedback loop that keeps checking the `isActive` expression block, then you can drop out of the loop when the expression is false.

So this didnt work for me, it actually spammed me of course since the notification was in the loop lol.  
But if I just go off of the expression like below, it still never send the clear notification.

Right, I didn't look at how to solve your exact logic problem, just show you the loopback.

I wonder if once it is cleared, the pipeline is no longer active which would keep it from getting to the last notification.

EDIT:  
Just use the [clear pipline](https://docs.inductiveautomation.com/docs/8.1/platform/tags/tag-properties/tag-alarm-properties)

Another option would be to adjust the dropout conditions
