Casting the Card

This card can be (Chrome) casted to a device (such as a Nest Hub) through the use of Home Assistant Cast.

Instructions

• Visit Home Assistant Cast and click Start Casting
• Enter your Home Assistant URL, and authorize your account.
• Click Start Casting and choose the device to cast to from the browser menu.
• Choose which view/dashboard to display.
• If successful, the view will be cast to the device.

Limitations

Casting Home Assistant dashboards comes with a number of caveats:

• Home Assistant Casting does not support the HA streaming component (source). This means clips playing and the ha live provider can not work. Other live providers such as jsmpeg and webrtc-card function correctly.
• The Javascript fullscreen API does not work (so the fullscreen button does not work, but see below for an equivalent).

Recommended configuration for Nest Hub

Using a panel dashboard with the following base configuration will result in the card consuming the entire device screen:
