Combining Multiple sensors - Reed switch not working
-
Hello:
I have a multi sensor with a DHT, PIR, NRF, and Reed switch. The PIR is connected to PIN 3, and the Reed switch is connected to PIN 2. The reed switch is setup exactly as the mysensors example here, ( https://www.mysensors.org/build/binary ) and works perfectly fine when only using that sketch. When trying to combine a few sketches, I'm getting everything else to work except for the Reed switch, and can't figure out where I've gone wrong. Is anyone able to possibly shed some light? My code is below, and really appreciate the help thank you.

Afaik the debouncer doesn't work with sleep(). Try without or just do something like a
gw.wait(5);before reading the value. At least I had the same problem and fixed it like that.

Thanks very much @LastSamurai removing the sleep function seemed to work, but the PIR reports like crazy!

Any other suggestions that might not trigger the PIR all the time? Thanks very much again!

@rhuehn now that you have a "wait", your loop is not blocked. Then after the "wait" elapses the loop start again and you send a new PIR state (which is certainly the same than the previous loop).
So you have to memorize the last state and check if the pir state changed in the loop. You send the msg only f state is different.
I hope my explanation is clear

thanks @fets have I specified the wait time at the wrong location? In the sketch below, everything works, BUT the PIR triggers 0 over and over and over again.....
