Widget like Toggle, Button, Switch or Shedule

In the Inssight page, only 8 widgets are found. How can I add a toggle, button, switch, or schedule for direct control from the dashboard? Can someone post a video tutorial?

First of all, welcome to the forum!

You can add your own custom HTML/CSS/JS widgets, by modifying the OpenRemote codebase.
