I’ve done a simple flow to interface a PIR, its been working great on a PiZeroW for quite some time. Today I went to add the flow to a Pi2 system. I exported the flow on the PiZeroW and imported it into the Pi2. Problem is it doesn’t work when deployed. Running the latest Raspbian with: python-rpi.gpio is version (0.6.3~stretch-1).
The pin numbers are the same and I’ve verified the hardware works by hooking up a meter to the PIR output pin 0 volts when idle, 3.3V on detect.
Here is my flow, exorted from the Pi2 system:
