Making a door lock with STM32WL
Hi Devs,
Recently I got into some RF stuff and planning to build a door lock app - with one device as a remote and another attached to the door controlling a sort of electromechanical system to latch/unlatch the door. I have tried a basic device-device communication, sending a command to open and close the door where on reception of the command from a remote, the node beeps buzzer. Wrote about this here (https://community.element14.com/challenges-projects/project14/sub1ghzband/b/blog/posts/project14-subghz---door-lock-app-part1)
To extend this further, I require some suggestions on system design and implementation plan on how multiple doors can be controlled.
1. A mesh type network between 3 or 4 nodes on the door would be suitable?
2. How the electromechanical side of control can be designed to latch/unlatch the door? (maybe would require an additional power other than onboard)
Let me know if you any ideas on this and probably we can discuss on how to extend this for more other applications and as a product.
