Add bouncetime? Problems with Bouncing on digital input!

[Rohrleitner]

Hello. My first garagdoor automation setup works really fine. The only problem is, that i have a "bouncing", everytime from "CLOSED-OPEN-CLOSED" on my reed switchs and i can see it switching in your log.

There should be a function for setting the bouncetime: https://sourceforge.net/p/raspberry-gpio-python/wiki/Inputs/

add rising edge detection on a channel, ignoring further edges for 200ms for switch bounce handling

GPIO.add_event_detect(channel, GPIO.RISING, callback=my_callback, bouncetime=200)

Ist it possible to set the bouncetime for each digital input in the yml? e.g. bouncetime: 200 in the yml? and if bouncetime >0 then run GPIO.add_event_detect?

Would be a great help if you could bring this in!

Hi @Rohrleitner

Yes, this looks like a good idea. Thanks. I'll add this to the list and try to get it implemented soon.

I would very much like to see this added too. At the moment I am looking at using hardware debouncing of PIR contacts attached to my Pi.

Hi,

I'm working on that, and have already a working version, but I have to clean up a lot of code :-( before I can create a pull request. Currently I have extended the digital_inputs config (https://github.com/BenjiU/pi-mqtt-gpio/commit/96bf4e11cd25b2d8e9d90113d8ad05959de1b846#diff-0ab99ddee45bf345e48d79ae48ea7ecd) with a interrupt-type (if none, its polling)

    interrupt:
       type: string
       required: no
       default: none
       allowed:
         - rising
         - falling
         - both
         - none
     bouncetime:
       type: integer
       required: no
       default: 100
       min: 1

and a bouncetime, that may be configured (default is 100ms).

Would that fit your needs? There are only interrupts for RaspberryPi, not for attachable modules yet.

Hi

Sorry missed your answer.

I'm interested to test tis for you.

I have the same problem how can i test?

digital_inputs:

• name: mare_closed module: raspberrypi pin: 25 on_payload: "TRUE" off_payload: "FALSE" pullup: no pulldown: no retain: yes
