Interrupts on inputs do not work

zolee28 commented 1 year ago

I'm trying to use mqttany with Openhab. Connection over MQTT is good, I can send commands to the I2C and control my lights. However I also want to use MCP23017 for inputs (button press). The inputs work as well, the problem is that the polling interval of 1sec is not optimal for me.

I saw that you have been working on interrupts for the pins, now this could really help as when you press the button it would immediately send its status to mqtt/openhab.

For me the interrupts do not work. I can see the input pin changing in the regular poll intervals.

Is there something I did wrong in the config file? I also saw this does not have any effect on polling "interrupt polling interval: 50"

Environment

MQTTany version: v.0.14.3
Platform: Raspberry Pi 4

Configuration

i2c:

  polling interval: 20

  mcp23017-1:

    interrupt polling interval: 50
    device: 'mcp23017'
    bus: 1
    address: 0x20
    mcp230xx:
      pin-a0:
        pin: 9
        direction: 'output'
        resistor: 'pullup'

  mcp23017-2:

    interrupt polling interval: 50
    device: 'mcp23017'
    bus: 1
    address: 0x21
    mcp230xx:
      pin-a0:
        pin: 5
        direction: 'input'
        resistor: 'pullup'
        interrupt: 'both'

Logs

Nothing comes up on debug logs regarding interrupts.

The polling interval option should be under mcp230xx, it's not picking up the option where it is.

Docs for that feature aren't merged, but you can find the updated MCP page here

Thanks a lot, works like a charm now!

So now the code looks like this;


     mcp230xx:
       interrupt polling interval: 50
       pin-a4:
         pin: 4
         direction: 'input'
         resistor: 'pullup'
         interrupt: 'both'

       pin-a5:
         pin: 5
         direction: 'input'
         resistor: 'pullup'
         interrupt: 'both'

I ran into a new issue however, so for ex. when pin-a5 is switched, it sends the command OFF - this is ok. When I press pin-a4, pin a5 goes to ON and pin a4 is OFF. Is there a way that the status of the pins do not affect one another?
