Primary volume

Screen: Room Devices — a room's TV & audio card.

What it is

The Primary volume buttons, TV or Amplifier. Shown when the room has both.

What to enter

Press the one the room's volume should use first. Amplifier is the default.

What it changes

In the house: The project saves this by itself. At the next Save & Deploy the app's volume drawer opens on that device.

In the app: The phone's volume drawer shows this device's volume first, and mute on a source tile mutes it.

If it goes wrong

• If the volume does nothing, the other device is probably the one in use; change it.
