Like to switch on/off light via GPIO

Development
#1

Hi guys,

I'm a completely new user with OctoPrint. I like to implement an addition function. I like to switch on/off the light with a button at Control Page, see attached picture. So I inserted the
following lines at control.jinja2:

        <button class="btn btn-block control-box" data-bind="enable: isOperational(), click: function() { $root.sendCustomCommand({type:'command',command:'M106 S255'}) }">{{ _('Light on') }}</button>
        <button class="btn btn-block control-box" data-bind="enable: isOperational(), click: function() { $root.sendCustomCommand({type:'command',command:'M106 S0'}) }">{{ _('Light off') }}</button>

Now I have to change the command. I need something like:

/usr/local/bin/gpio -g write 18 1
/usr/local/bin/gpio -g write 18 0

I'm not familiar enough with programming to know how the command has to looks like. Can someone helps me, please?

Are you sure you don't want to use a plugin for this?

I like to try OctoLight. But I get an error if I try to install :frowning:

    Complete output from command python setup.py egg_info:
    Could not import OctoPrint's setuptools, are you sure you are running that under the same python installation that OctoPrint is installed under?

Using Pluginmanager it works

Thanks!!

Standard GPIO at OctoLight ist GPIO13. But I can't measure 3,3V.

After updating WiringPi I can switch GPIO via shell

OctoLight works now. At configuration you have to use physical PIN number, not GPIO number!!
