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.

    2013: The proof of concept prototype for the door latch/unlatch (Bluetooth, WiFi, XBee, RFM95 LoRa Radio 900MHz, RFM96 LoRa Radio 433MHz, RFM12B 433 868 915 MHz) consists of a various components.

    That helps. I am also looking at some off the shelf low cost solenoid valves.

    Great! Thanks for sharing this 🙂

    I am porting your example code to the ST platform now. Was going through your portfolio page @lucpaquin_82882 . Very informative content and practical projects. Kudos to you – thanks and keep them coming…

    @ngu25 Hello sir

  18. bytemaestro.#0

    I’m goona start making a face recognition door lock using Arduino R4 wifi
    Any recommendations how to make it

  19. ngu25#0

    Hey @bytemaestro. ,
    That will be a good project. I used allowed frequency to operate on – to send packets to trigger the door actions. Now that you’re going to use face recognition, how do you plan to implement recognition algorithm?

  20. ngu25#0

    You can try edge impulse small model face recognition running on R4 wifi.

  24. bytemaestro.#0

    not yet this is what i am asking u also can I program in python beacause the recognation video I am understanding is made in python

  25. josephogbonna#0

    @ngu25 which gateway do you use for the stm32wl to access the internet
