Hello rickkas7,
Thanks for this code, works very well. I am have adapted for sensing the movement using PIR sensor.
customer needs that the device should withstand for months. So I have designed the way to wake up the device when there is a motion detected. I have connected my pir sensor output to A7 pin so that device wakes up if there is a motion. However, they required that the device should publish an event every 6 hours. So that i have differentiated with publish event every 6 hours and publishing variable by adding when sensor value =1 (so that we could find there is a motion).
But in my case, it publishing variable at the same time as publishing event every 6 hours. I need to differentiate in showing output if there is a motion. Kindly anyone advise me please.
I am getting sensor value as high every alternate time( 00 1 1 001 1 001 1 ), I am confused about it.
this is the adapted code:
