Hi, this is a continuation of a discussion started elswhere. I have connected a pushbutton to Pin 18 of RPI4 with a pullup resistor to VCC+3V. Pushbutton-Presses are not reported by MQTTany (MQTTany 0.14.3).

/etc/mqttany.yml:

mqtt:
 
  host: 'localhost'
  port: 1883
  client id: 'test'

gpio:
 pintest:
 pin: 18
 pin mode: 'input'
 resistor: 'pullup'

Just to be on the safe side, I have connected GND to Pin No.6 and the other part of the Pushbutton to Pin No. 18 (GPIO 24). The pin numbering can be found at https://www.raspberrypi.org/documentation/usage/gpio/

python3 mqttany/mqttany.py -vv results in:

aaaaah. OK, I didn't know that :-)

OK, here is an update. I use gpio version: 2.60, retrieved via
git clone https://github.com/WiringPi/WiringPi.git cd WiringPi/ ./build

Now i issue the following commands:
`gpio mode 5 input

gpio mode 5 up
`

After that, I can reliably read any pushbutton actions with 'gpio read 5'. The GPIO 5 used by gpio corresponds to my physical pin 18 (you can get this via the listing obtained by gpio readall):

gpio readall

+-----+-----+---------+------+---+---Pi 4B--+---+------+---------+-----+-----+

Now the first question is, which Pin Number is MQTTany refering to? I would like to avoid testing stuff on the wrong pin number... Is it physical pin 18, is it GPIO Pin 5 according to GPIO readll or is it PinNo. 24 according to the official wiring diagram?

See this page in the MQTTany docs for the definitive reference when using MQTTany.

A simple fix: you need to enable interrupts.

Adding the option to your config gives this:

mqtt:
  host: 'localhost'
  port: 1883
  client id: 'test'

gpio:
  pintest:
    pin: 18
    pin mode: 'input'
    resistor: 'pullup'
    digital:
      interrupt: both

Please post your complete config file, looks like there is an error.

The second thing it is complaining about is that you need the version option, you did not include that in the config you posted originally and I did not add it to the updated one I posted.

The only thing I see is that the options in pintest are indented 1 space, you need to use exactly 2 spaces in YAML.

Please note, I'm using "pin 24" here because the documentation of MQTTany says that SoC is default, and for PIN#18 SoC is 24.

mosquitto_sub -t "test/gpio/pintest" now correctly reports OFF ON OFF ON etc. which seems to be correct... I will monitor that and report back...

CrazyIvan359 Mar 16, 2021

Looks like it's working now!

If you want to invert the signal so that a LOW/GND signal sends ON to MQTT, there is an option for that.

meschmesch Mar 16, 2021

Ok, which option is that?
By the way, thank you very much, that really helped a lot!!! So, the solution was choosing the correct SoC "Pin number" in combination with
digital:
interrupt: both

Thank you!

CrazyIvan359 Mar 16, 2021

All options are listed in the documentation, the Digital page under GPIO will show you where to put the invert option.
