Piston to re_arm alarm

[babychef]

**1) Give a description of the problem
Cannot figure out code to re-arm sensor after back door sensor closed. I have alarm.com alarm system. Have installed SmartThing switches called Alarm Away, Alarm Stay, and Disarm. Have routine that turns on Alarm Stay at night. However, have a son that lives in garage apartment that will come in the house after that time, disarm the alarm, but not re-arm when he goes back to his apartment.

2) What is the expected behavior?
I would like a piston that will re-arm the system every time it is disarmed, between certain hours (1 - 8 am), and after the back door sensor is closed.
3) What is happening/not happening?
nothing is happening

**4) Post a Green Snapshot of the piston

5) Attach any logs (From ST IDE and by turning logging level to Full)
no logs

Fundamentally I believe the problem is that you are subscribing to two “triggers” – Switch 2 changing to off, and Contact Sensor 1 changing to closed. These cannot be simultaneously true, and therefore the piston is not executing the “then” section.

What you need to do instead is make one of them a condition. Like this:

IF
{$hour24} is inside of range 1 and 7
and
Switch 2’s switch is off
and
Contact Sensor 1’s contact changes to closed

THEN
with Switch 2
do Set switch to on

Conditions and Triggers: The difference?

as new users join the community, we expect that at some point many new users will ask this question. so, heres a quick note. conditions: if there are NO triggers in a piston, webcore checks the conditions to decide which events that piston should be subscribed to. if there are triggers in that piston, webcore does NOT subscribe to the events the conditions refer to. triggers: if there are triggers in a piston webcore ONLY checks the triggers to …
