# RelayBlinds usermod This simple usermod toggles two relay pins momentarily (defaults to 500ms) when `userVar0` is set. e.g. can be used to "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. A simple `presets.json` file is available. This makes the relay actions controllable via two presets to facilitate control e.g. the default UI or Alexa.
