On my HA system that was just retired (replaced with a Raspberry Pi with much more memory), I had the changed the default dashboard to be something very simple: Just one area showing the four devices in my system each with an on/off button. I have no memory of how I did this- did I edit a yaml file or something? If someone could point me to directions for doing this, I would be greatly appreciative.
Hello,
Click on your username on bottom of the sidebar menu and scroll to select the default dashboard in Browser section this will be only for the device you are on.
