Cant get Domoticz to Add GPIO

[DanM]

Hi,

I have the following in my rc.local:

Code: Select all

sudo sh -c 'echo 26 > /sys/class/gpio/export'
sudo sh -c 'echo in > /sys/class/gpio/gpio26/direction' 
sudo sh -c 'echo both > /sys/class/gpio/gpio26/edge'

I can see the files in /sys/class/gpio/ and applying voltage to the pin changes the value there as it should. In spite of this Domoticz always starts saying GPIO has 0 inputs. Any ideas?

Thanks,

Dan

I know replying to myself is bad form.. but I've done some further digging and it seems that restarting (i.e enabling and they disabling the 'Generic sysfs GPIO') finds the GPIO correctly. My Log entry ends up as follows:

Code: Select all

2018-09-17 13:33:53.303 Status: Sysfs GPIO: Startup - polling:no interrupts:no debounce:50msec inputs:0 outputs:0
2018-09-17 13:34:19.923 Status: Sysfs GPIO: Worker stopped   <- this is the enable / disable
2018-09-17 13:34:22.561 Status: Sysfs GPIO: Startup - polling:no interrupts:yes debounce:50msec inputs:1 outputs:0
2018-09-17 13:34:22.561 Status: Sysfs GPIO: Edge detection started 

It seems like domoticz may be starting before rc.local is finished, is there any way to delay the domoticz start (that wont be overwritten when I update - I'm assuming domoticz.sh gets replaced). Or is there a way to enable and disable hardware in LUA?

/etc/init.d/domoticz.sh doesn't get replaced during an upgrade, so maybe that's the place for you.

Also the Wiki tells you to use this folder, did you read it?

@DanM, any luck?
