Innovative Presence Detection Using Smart Door Locks

I’ve been exploring different methods to improve presence detection in my smart home, and I stumbled upon an interesting idea that I’d love to share and discuss with the community. The concept revolves around using connected door locks to determine if someone is home, which I believe could be more reliable than traditional motion sensors or Wi-Fi tracking.

Here’s the gist of it: If the last person to leave the house manually locks the door using the keypad, we can assume the house is empty. Conversely, if the lock is disengaged in any way while the house is marked as empty, we can infer that someone has returned. This method doesn’t track who is home, but it simplifies the presence detection process significantly compared to managing multiple sensors and devices.

However, I’m not entirely sure if this approach is feasible with all smart locks, especially regarding the ability to detect how the lock was engaged or disengaged. I’ve been researching the Z-Wave binding documentation but haven’t found a clear answer yet. Has anyone implemented something similar or has insights on how to achieve this? I’d love to hear your thoughts and experiences!

This approach could potentially eliminate some of the common issues with traditional presence detection, like missed motion or disconnected devices. It would be fantastic to see if this idea can be turned into a practical solution for the community. Let’s brainstorm together!
