I'm not any good with Linux, but I want to see/add icons to the repository used by OctoRelay for the buttons. Any help getting to them would be much appreciated.
It looks like that plugin is allowing you to enter your own custom HTML into the box. So you should be able to use whatever icon you like.
You could try using a FontAwesome 5 icon, since they are included in OctoPrint, if you enter
<i class="fas fa-plug"></i> see what happens.
The full list can be found at Font Awesome
Thanks, it works. Now I just have to figure out how to get it to gray and dim.
Got it dimming, but cannot get the icon to be Gray instead of blue.
