Just another door lock

lock

This project is my attempt of a door lock that has the following considerations and features in mind:

• Free software and easily hackable
• Can be used on an existing key-based locking mechanism
• Does not compromise security (at least hardware-wise)
• Does not compromise usability (existing system must continue to work in the same way)
• Safe in the event of a power failure
• Impossible to lock you out using a key
• Indoor modifications only
• 3D print as much as possible (we're not going to 3D print a motor, but you get the idea)
• Low cost (aiming for less than $10)
• Compatible with most doors (focus on EU for now)
• Detect manual opening

I will also allow some limitations:

• Will assume working wifi
• Will not be low-power, so there will be a cable on the door
• The existing lock cylinder

Existing work

There are already some Smart Locks out there that are pretty close to this one, but they miss one or more of the above features. Also, I just want to make my own.
