Ok thanks for the solution guys
Ok this piston Iām getting really confused about. Sorry Iām a noob. I tried changing the piston to WHILE so that it cycles but now it doesnāt seem to trigger. Can someone help as to why the piston wonāt trigger when set to Away mode?
Ok nevermind i think Iāve totally messed it up. Lol.
Hi, everyone. Iām new to CoRE, but I understand the concept somewhat as Iām just now moving from Rule Machine (I know, Iām ancient). CoRE looks way better, but itās pretty intimidating. Iām trying to compare two temperature sensors in my house and send an alert if they differ by more than a few degrees (and preferably an alert when they are back below the threshold as well). Any idea how to set this up? Thanks so much!
May I recommend skipping CoRE and going for webCoRE? 
Oh man, and I just installed CoRE too! 
Is webCoRE where the future work is going to be done? If so, Iāll move over to it.
I figured out the comparison part. Just have to work on the notifications for switching between the states. I have a basic piston. Whatās the easiest way to execute an action when a piston or condition is no longer true? Should I just make another piston or add a condition to the existing piston that is basically the reverse of what Iām matching on, or is there an easier way?
Iām having an issue- I want to setup a piston that checks the status of a device when a routine is run, and notify if its not in the proper state. Sounds easy right? The issue is the device I want to check is a custom devicehander (wemo coffeemaker) so Iām not sure what I need to do in CoRE or what I need to change in the devicehandler to make this work.
Is there a way to manually start a piston? What I want is a way to start an overhead fan at high speed and then after 30 minutes to slow the fan down to a slow speed. I have written a piston that will do this when i turn the fan on but I donāt want that every time.
why not make a virtual switch and trigger it based on that? then you can just use that switch when you want that function.

Hit its Test button? 
Sounds,easy. Where would I find the test button?
Ok. That would work even better. I see an faq that shows how. Thanks
CoRE or webCoRE?
In CoRE you can create a ātapā and thenkickstart it from the CoRE dashboard. webCoRE did not yet get the taps - but you can test the piston from the dashboard - the equivalent of Simulate in CoRE.
Used the virtual switch and it did just what i was looking for.
Thanks
My auto goodnight piston is not working, not sure whatās happening.
Basically what I want is if time is between 11:30 PM and 5:00 AM, and all of the few motion sensor is inactive, then run the good night piston.
Do you need the wait for false state?
Iād try it without it as you want the piston to be true.
But I want all of those motion sensorās to be inactive for at least 10 minā¦ There may be time when Iām still downstairs, watching TV or anything and knowing me, I would trip the motion sensor within 10 mins for sureā¦ this way I can make sure that Iām retired for the day.
Is there any other way to make sure Iām done for the day and then run good night?
The wait will take care of the False state. It is not needed.
To be honest, the built in Good Night Routine works really good for this. I have mines on a 30 minutes and starting at a specific time. I use a backup webCoRE Piston just in case it didnāt fire after a specified time.
It works when configured for specif time, but I do not know that specific time.
I need to run it based on occupancy of first floorā¦
If after xx PM if first floor is empty for minimum 10 minutes run good night.
Let me check if in default good night routing, I can configure for motion sensors or not, but my guess we canāt.
the wait will just wait, what if once all motion sensors are inactive, i forgot to take something and come back again within a min? It wonāt reset the timer, will it?
