Quickstart to use the Raspberry Pi with our ImSwitch and UC2-ESP

The Raspberry Pi connects the UC2-ESP via USB and the USB3 camera to the ImSwitch that runs in Docker. You can access the frontend via your browser on a phone or laptop. It's experimental at the moment!

Login Data for Raspberry Pi (SSH / Login)​

The Raspberry Pi login credentials are:

  • Username: UC2
  • Password: youseetoo

It runs the Raspberry Pi OS Light version with a Docker integration of our systems, linked on Twitter. You can log in via SSH and start the ImSwitch server.
