Hi all,

I am just getting stsrted and could use a little help. I want to use the alarm to activate a light connected to a raspberry pi.

Any ideas on where i should start? Do i use the API endpoint or is there a way for the brainframe client app to extend to switch on a light when an alarm is triggered.

You can connect a camera to BrainFrame and configure an alarm using the BrainFrame client user interface. When the alarm is triggered, BrainFrame will send a message to your application through REST API. You can then develop your own application to listen to the alarm message and take appropriate actions, such as turning on a light.
