gpiozero buttons stop working

[duckredbeard]

I have a Raspberry Pi 4 running a code that monitors several buttons. When a button is pressed or released, it does a requests post and prints two lines. After a few days, all of the buttons stop working. No requests posts, no lines printed. And no errors indicated. The code simply stops working. I have been running this manually lately so that I can manually stop and restart it, and that always gets it going for a few days. But only for a few days.

I am thinking it is a problem with gpiozero, so I've tried to convert it to rpi.gpio but I keep getting bounce issues. I've tried a few AI code converters (blackbox.ai and ChatGPT) but nothing is really working out of the box. Should I reinstall gpiozero? Should I start with a fresh new install of the OS?

When it stops running does the garagerun LED stop blinking?

Did you look at your output to check if every response prints a status message? I would check that for every "Garage entry door unlocked at..." there is a corresponding "Response...".

There is no line printed and there is no response code. The LED light continues to blink. It seems that it is simply no longer processing the button inputs. I can remotely cause a button input by controlling a wifi controlled switch. That switch controls the ground for a PIR as well as provides a ground input to a GPIO. This is "motionenable" on GPIO19. When this remote switch is activated, the ground allows the PIR to work and I get the feedback that the PIR is active. A second function of this is that I can test the detection of button inputs without having to go to a door, and I can test it from any where. Another app for the switch can confirm that the wifi controlled switch is functioning. If the pi doesn't do what it is supposed to do (requests.post and print line), then I can only say it is the RPi's fault.

I will build up a spare Pi with a fresh OS install today and copy over the script today. If that fixes it then it is OS or hardware. If it doesn't fix it then it must be code...

All your functions print something. Either they are not running, or the output is not displaying. Which is it?

Everything associated with a button stops working. Nothing prints, there is no request post happening. It is like the buttons aren't pressed.

I don't understand "Everything associated with a button stops working. Nothing prints".

In your first post you said this:
"When a button is pressed or released, it does a requests post and prints two lines. After a few days, all of the buttons stop working"

That makes it sound like there was printing, and then printing stopped. What was the last thing printed? Most of your functions print something, perform an action, and then print something. If you see the first message printed but not the second, it would point to a problem performing the action. If the last thing printed is the second message, that points to the functions not getting called.

The last thing that is printed was is always the "print(f"Response: {response.status_code}")" line, and that code is always 200, which indicates that the last event's task is complete and successful. I do not get the first line that prints what had happened like the "print("Right garage door open at", current_time)" line for the newest event.

Do the motionmon and motionact LED's stop working?
