HVAC Pump Still running help

#1

1) Give a description of the problem
Looking for feedback and assistance on a piston to alert when a pump is still running

2) What is the expected behavior?
If the Pump remains running for 5 minutes to trigger an alert to check the line for a clog. however if the pump drops back to 0 to reset the variable to false

3) What is happening/not happening?
So far I used a “Laundry’s Done” Piston I found and am using for my washing machine and have modified it. I’m just getting stuck on how to change the variable at the end where is the pump actually shuts off to reset the variable and send no notification.

4) Post a Green Snapshot of the pistonimage

If all you care about is whether or not the pump is still running for 5 minutes, then just check for that.

Change the piston so that you eliminate the first stuff…

Mike,

Thanks for the heads up. I guess I was just over complicating things here. I’ve read up on some of the energy monitoring pistons and the common thread was to add a variable to avoid false alarms. I do think I may have figured it out still using the variable but will most likely just change it to the simple piston you recommend, I prefer easy peaze.

Could take a quick peek at this and see if it would work as I was looking for with the variables? I just want to make sure I’m getting a grasp of this whole WebCoRe thing :slight_smile:

Hmm… OK, I get the desire to avoid false positives. But a 5 minute long false positive?

In order for the trigger to be true the power has to stay above a certain wattage for 5 whole minutes.

But anyway…let’s proceed with what you want to do. What you have there won’t work. You can’t tuck the Notification IF statement inside where you have it as it then relies on “rises above” to be true…which it probably won’t be in five minutes. It will just be at a certain power level.

If you really want to use the variable to do this…then you really need to do it the way I show below. All three statements on their own. Three different triggers, all happily playing together nicely.

MIke thanks for pointing out my errors. I’m still most likely going the route of your first recommendation because I do like things to be straight forward and easy. I do appreciate you taking the time to show me the correct way though. I’ll figure this programming WebCore out one day.
