1) Give a description of the problem
Contact Sensor 31 just open, after 2 minutes Contact Sensor 30 opened, but the timer counting for both are open for same 2 minutes and send Push notification.

Each Contact Sensor has its own timer and send Push notification ( ex : Contact Sensor 30 was opened 2 minutes, and Contact Sensor 31 was opened 5 minutes . )

If you want independent counters, you will need to create independent triggers. As you have this now all three will trigger this piston and you will get an increment for each one if they are on act the same time but all in one counter.

Thanks @guxdude. Now I create a piston for each contact sensor.
