Push button interrupt now functioning properly
-
Hi there, I just finished building my push button sensor to act as a doorbell for my system.
I used the basic binary switch sensor example as my basis. I have it connected to pin 3 on my arduino pro mini clone. When reading the serial logs, i learned that the pin registers high (1) when not pushed, and low (0) when pushed. So, i changed the send from 1:0 to 0:1 to send the correct state to Vera. all works fine there.
When i tried to implement the sleep with interrupt, it seems as if the arduino sleeps indefinitely and does not wake upon state change (button push).
Any idea as to why?
Here is my code

The deboncer Bounce doesn't go well in combination with sleeping in my experience. Sleep for a short while in the loop before reading the pin, instead, to make the bounce settle.
There's an example using this method among the examples in the mysensors library, called binary switch sleep something...

I'm getting some better results. Right now i have a .sleep(20) prior to reading the input.
I also set the interrupt to detect on FALLING edge. Seems to be more stable.
However, about one out of every 10 times i push the button i get a "1, 0,1" instead of a "1,0" .
I then changed the pinMode to "INPUT_PULLUP" vs just "INPUT". I also changed the interrupt condition back to "CHANGE" and that seemed to do the trick to reliably capture button presses. Thanks for the quick response!!

But whatever works. :thumbsup:

I made that change and removed writing the pin to HIGH.
However, in both cases, while i'm correctly seeing reads in the serial monitor, I'm not getting any status change on the motion created in VERA. I did a clean inclusion to vera (the node and sensor were never added to vera prior) and did the normal, include, reload and then turn on and off the sensor to get the sensor name and version details)
Serial monitor reports normal, but not vera.
Ideas?!

strange. I changed the NODE_ID to 1 vs using the default AUTO selection from the gateway, and now I am seeing status in Vera. i think the gateway is having issues properly assigning node IDs. Will have to look into that some other time. Not a big deal for me as I have an excel table of all of my nodes anyway.
here's some photos of my doorbell node

I'm not familiar with how the Vera works. The gateway doesn't assign node ids, it's the controller that has to do that. I don't know if Vera supports that or not. Someone more versed in Vera should answer this.
