Problem with RPi Nano

[mackowiakp]

I installed Domoticz on RPi Nano and it works good. But I have problem with cooperation Domoticz and GPIO. GPIO is set to sysfs GPIO, and it automatically recognised exported pins. But if I use particular pin as output port, it is possible to set/rest it using gpio command but it is not possible from Domoticz defined On/Off switch. No errors in logs.

Below outputs fron console:

 root@NanoPi-NEO:~# gpio exports
GPIO Pins exported:
   7: out  1  none    
  15: out  0  none

So I exported pin according to WiringPi numbering. So what I am doing wrong?

Have you tried the sysfs switches plugin?

https://github.com/flatsiedatsie/GPIO-SYSFS-Switches

OK. I downloaded and installed plugin.py according to https://www.domoticz.com/wiki/Plugins/G ... S-Switches

No lucky so far. Plugin running by itself shows such error:

Code: Select all

./plugin.py: line 12: syntax error near unexpected token `('
./plugin.py: line 12: `         <param field="Mode1" label="GPIO output pin numbers (comma separated)" width="100px" required="false" default=""/>'

Any idea what is wrong?

[mackowiakp]

OK. Finally I got it working. But, is it possible to reverse state of sysfs GPIO outputs in plugin? Of course it is necessary to use command like this:

Code: Select all

/bin/echo 1 > /sys/class/gpio/gpio#/active_low

But is it possible to change it when Domoticz plugin starts ? If so what I have to change?
