Alarms
alarms of a room lists alarm sensors (binary_sensor): while one of them is on, the room blinks, whatever the map (even with No map), with the kind of alarm written on it in its colour. The kind comes from the device class of the sensor: red for smoke, gas and carbon monoxide, orange-red for heat, blue for a water leak, light blue for cold, orange for safety, problem and tampering. With several alarms on, the most serious gives the colour.
alarm_view: yes: the camera goes to the room when one of its alarms goes on, from at least 65° above, with its level and the levels under it shown and those above hidden.type3d: alarm: the objects of a sensor blink too, as the dishwasher with the leak sensor under it.

The alarm panel of the house has a box of its own, and with state_colors: yes the open doors turn red while it is armed (see Room colours).
