Just read that and was about to delete my post. Thanks Guys 
So I can get all my lights to turn on, but I canāt get them to turn offā¦
For example this turns on the light upon door opening or motion being active but it never turns off.
The 30 seconds is just a testing number, I had it set to longer but it doesnāt turn off regardless of length of time. Iām probably missing something simple with most of my pistons.
I donāt understand the difference between a simple and latching piston yet either. I used simple with this one because I just want the motion to keep resetting the time, but if the time expires turn out the light. Likewise, if the motion becomes active again, turn the light back on.
The door is just a trigger. Turn light on every time door opens regardless of motion.
Iām trying to set up my first piston. Iād like advice on which type to use. Basically, Iād like changes in Smart Home Monitor alarm mode to arm my alarm accordingly. So
If SHM changes to Armed/Stay, Then Set my alarm to Stay
if SHM changes to Armed/Away, Then set my alarm to Away
If SHM changes to Disarmed, Then disarm my alarm.
Thanks for the help!

You got the ātriggerā meaning wrong. The way you have it, only the door will control the lights. Door opens, lights turn on. Note that motion with the door not changing states will not turn your lights on. Lights will only turn off when the door closes, IF there is no motion (which I think is pretty impossible to do) - use a condition for the door as well: door contact is open, rather than āchanges toā
In my case the lights donāt go off even if the door is closed.
Do I need 2 pistons? One to turn on the lights and one to turn them off?
Lights will go off when the door closes, IF the motion sensor is inactive, which I assume is impossibleā¦ again, you donāt need two pistons, you need ādoor contact is openā instead of ādoor contact changes to openā.
Hi all! Quick one I hope. Iād like my thermostat to increase from its current setting by X degrees, as opposed to being set to a specific temperature, in response to a trigger. I canāt figure out which task to use to accomplish this. Any suggestions?
@ady624 can you help please?
Thanks!
Which function is that? I donāt see any Task called āIncrease set pointā or similar.
Is your alarm panel actually integrated with SmartThings? Thatās a whole separate project that involves installing hardware into your alarm panel. It works perfectly once set up. Details: https://community.smartthings.com/t/ad2smartthings/
Youāre a good beta tester, you try out all the possibilities lol 
Hi Folks
I recently purchased Harmony Elite remote with the hub and have integrated it with smartthings and Alexa. Unfortunately Alexa cannot control the volume of TV using the integration. Short of the Harmony developers updating the integration to have Alexa call pass each of the remote key, it is not going to happen. There are some threads on hacking the volume control. I was wondering if CoRE could come to help.
Basically what I am looking for is to be able to create a virtual dimmer and when I increase or decrease the dimmer setting trigger a CoRE piston to check the current Alexa mode and, somehow figure out whether it is using AMP or TV and then trigger a volume up or down activity and then switches back to the activity it was on.
Wondering is this something doable or if there is any other better option.
Thanks
Ok letās try this instead.
I want the closet light to come on if either the door opens or if the closet motion sensor is active.
If the door is left open and there is no motion I want the light to turn off.
If the light goes off with the door open and there is motion I want the light to come back on.
I donāt want the light to go off if the door closes and there is motion (walk in close with door closed).
In RM I had 2 rules to make this work. I donāt mind having 2 Pistons if thatās what it takes with core.
Single latching piston:
IF
Door changes to open
OR
Motion changes to active
THEN
Using light...
> Turn on
BUT IF
Motion changes to inactive
THEN
Using light...
> Wait 30 seconds (optional)
> Turn offSome DTHs allow for step up/down. If not, a combination of save attribute to variable, set variable = variable + x, load attribute from variable should get you going. That attribute is coolingSetPoint
Thanks will check it out
Yes, I have the integration done. But it suddenly hit me that while I can arm the alarm and I can āarmā smart home monitor, they donāt actually talk to each other. Ideally, Iād like to be able to arm SHM and have it arm the alarm and vice versa.
Iāve played a little bit now with the idea and this is what Iāve created:
It just seems that I should be able to make this a little more efficient.

Iām not using the AD2SmartThings project, exactly. I am using a Raspberry Pi instead of the Arduino. Iām using the AlarmDecoder smartapp (https://github.com/nutechsoftware/alarmdecoder-smartthings).
Iāll take a look at the AD2SmartThings app but I have a feeling it wonāt work with this implementation.
Hi, what does the āasSleepā and āasHomeā tasks do on a Tstat?
Would really like help to fix my piston as my light blinds me at night.
Iāve set it up if bedroom light turns on at night, dim to 10%, which would be fine, but the dimmer FIRST fades up to 100% in 3 seconds, THEN dims down to 10%. Is there a piston so if the bedroom light turns on at night, it goes straight to 10% ?
