Python Plugin: GPIO SYSFS Switches

[blauwebuis]

This plugin automatically creates switches for GPIO pins.

- You can input a list of pins
- The plugin creates a switch for every pin.
- It exports every pin and sets its direction to output (using shell commands).

If you toggle the switch, the pins will also be toggled.

Thanks and great work! I will test it this weekend

@BlauweBuis.
First of all thanks for the effort for writing this script.
At the moment i'm trying to get a Anavi Flex HAT (RabbitMax Flex) working.
http://anavi.technology/#products

The HAT uses GPIO 29 for a relais/switch.
Programming is not my daily skill so could you give an example of putting in th GPIO 29 in your plugin.py script?

Is Domoticz picking the script by itself or do I have to run in before starting Domoticz?
While running plugin.py tells me there is an error on line 18, Import domoticz

Thanks for reply in advance.

with regards
Arjen

@arjenw:

- You install it just like every other plugin.
- You don't have to change the script. You can simply add the desired pin in the Domoticz interface, under hardware.

Please read the documentation.

@BlauweBuis

Thanks for pointing n the direction of the Wiki for installing plugins.
I followed the directiosn.
Installed Python
rebooted the RPi.
Added the Hardware, but there was no option for putting in a GPIO port.
Do i have to put the file plugin.py in its own directoriy under ./domoticz/plugins/??/plugin.py
See picture 2 for Domoticz log.

Yes, it should be in a directory like that. Something like:

domoticz/plugins/sysfs_switches/plugin.py

You selected the wrong hardware too. It should be "sysfs pins" or "sysfs switches" (I just changed the name of the plugin to make it more recognisable)

[arjenw]

BlauweBuis,

- Created the filesystem folder /home/pi/domoticz/plugins/sysfs_switches
- Created new file plugin.py with the latest content
<plugin key="SYSFS-Switches" name="SYSFS-Switches" author="blauwebuis" version="0.1.0" wikilink="http://www.domoticz.com/wiki/plugins" externallink="https://html5zombo.com/">
<description>
- made executable plugin.py
- rebooted Raspberry Pi

>> Result: in Domoticz the hardware mentioned is not shown in the list.

Is there a file (location) where i can looking to for debug information regarding this plugin?

regards
Arjen

[blauwebuis]

Hey Arjen

In theory you did everything right.

Check your log. Does it mention the plugin system booting?
Are you running the beta?
Do other plugins work?

[arjenw]

Running latest beta.
Installed additional plugin
There is still no Hardware as described

Do I have to alter any script to load the plugin? For example domoticz.sh?
