Setup

Flash the Raspberry Pi

sudo apt install rpi-imager
rpi-imager

Select your Device, OS, and Storage. In my case:

• Device: Raspberry Pi Zero
• Operating System: Raspberry Pi OS (32-bit)
• Storage: /dev/mm....

Then click "Next", and "Edit Settings":

• Set Wifi SSID + Password to your local WIFI network
• Enable Key-based SSH authentication to "user" with an ed25519 key
• Hostname: r8.local
• XXX

Add to your /home/user/.ssh/config:

Host r8
    Hostname 192.168.0.12  # adjust the local IP
    User user
    IdentityFile /home/user/.ssh/id_ed25519

Store the keyblepy secrets in pass

Press and hold "Unlock" button until the yellow light flashes in order to enter pairing mode. Then register the user:

cd keyble
./keyble.py --register --qrdata <qr_data> --user-name doorbot --user-key <user_key> --verbose

This is how you get the variables (you should store them in pass):

• pass edit r8/keyblepy/qr_data: scan the QR code on the key card with Delta Chat, use the text
• pass edit r8/keyblepy/user_key: generate a 32-character hexadecimal string
• pass edit r8/keyblepy/user_id: 0 if the raspi is your only device, 1 if you have an additional app configured.
• pass edit r8/keyblepy/device_address: the Eqiva's Bluetooth MAC address, best you scan for it with the laptop. The device is called KEY-BLE.
