simple_alarm is capable of detecting intruders. It does so by checking if lights are being turned on while there is no one at home. When this happens it will turn the lights red, flash them for 30 seconds and send a message via the notifiy component. It will also flash a specific light when a known person comes home.
To set it up, add the following lines to your
simple_alarm: # Example configuration.yaml entry known_light: light.Bowl unknown_light: group.living_room
- known_light (Optional): Which light/light group has to flash when a known device comes home.
- unknown_light (Optional): Which light/light group has to flash red when light turns on while no one home.
