This simple usermod toggles two relay pins momentarily (default for 500ms) when userVar0 is set.
This can be used to e.g. "push" the buttons of a window blinds motor controller.
v1 usermod. Please replace usermod.cpp in the wled00 directory with the one in this file.
You may upload index.htm to [WLED-IP]/edit to replace the default lighting UI with a simple Up/Down button one.
Also, a simple presets.json file is available, this makes the relay actions controllable via two presets to facilitate control e.g. via the default UI or Alexa.
