<![CDATA[MMM-Universal-PIR - ‘GPIOcommand exited with error!']]>Hi

With no warning (I haven’t carried out any updates) MMM-Universal-Pir is now failing. It shows under the ‘PIR SENSOR’ heading on the MM screen ‘gpioCommand exited with error!’

Config is:

                    module: "MMM-Universal-Pir",
                        position: "bottom_right",
                        config: {
                            gpioCommand: "gpiomon -r -b gpiochip0 23",
                            onCommand: "wlr-randr --output HDMI-A-1 --on --transform 90",
                            offCommand: "wlr-randr --output HDMI-A-1 --off",
                            deactivateDelay: 120 * 1000,
                            }

and in a terminal gpiomon -r -b gpiochip0 23 shows events when the PIR is triggered and

wlr-randr --output HDMI-A-1 --on --transform 90 and wlr-randr --output HDMI-A-1 --off still control the screen.

gpiomon is v1.6.3

What can have changed?

Steve

I had no idea about that, but now that you’re using Docker:

The gpiomon command is called inside the container (doesn’t work) and you call it for testing on the host (does work).

So I assume you have the newer version of gpiomon running in the container. So update the command in config.js to the new syntax described in the module README and try again (the new command will fail on the host but should work from inside the container).

It never occurred to me the container would update things unannounced!

the container does not update things on your host, but the container itself is running debian and (if you are using karsten13/magicmirror:latest) the debian version of the container image switched from bookworm to trixie …

The Docker container has gpiomon at v2.2.1. It never occurred to me the container would update things unannounced!

Many thanks for your help

but gpiomon -r -b gpiochip0 23 works in a terminal when pasted from the config.js file, very strange

It’s just stopped working!
