A small solution for motion registration. Based on Raspberry PI 4 and appropriate DIY components.

Brief explanation: When PIR sensor registers any motion, the script logic is checking the status of the owner (is he at home?), and then, if the owner is not at home, noIR camera takes a shot and send it to telegram. In case when the owner is at home, the camera doesn't take a shot, also PIR sensor pauses for 10 seconds.

Example of notification telegram message:

This solution is one part of the personal smart home idea that runs on the Raspberry PI board(s).
