Yes, the project does not make a ton of sense but it was for me the opportunity to learn ESP32 and have some fun. The outdoor module is constantly in deep sleep and only wakes up for a few seconds when the button is pressed. I put a 1000 mAh cell as that was the biggest capacity that fit the enclosure, that's probably way too much as in deep sleep the ESP32 barely consumes anything.
The indoor module is plugged straight into a wall socket so no batteries. When someone is at the door I am notified by Michael Scott: https://www.youtube.com/watch?v=umDr0mPuyQc (maybe I will get tired of this, for now it's still fun)
