S1 UnleashedStep 1 of 5
Step 1 · Browser

Turn your S1 Plus into a Home Assistant kiosk

One USB cable, about ten minutes. Your panel's own software is backed up first, so you can always undo.

One-time setup, if any
Nothing to install. macOS lets the browser talk to the panel directly. If you use adb on this Mac, run adb kill-server first: only one program can hold the panel.
One Zadig step, once. Windows needs the WinUSB driver for the panel's recovery mode. With the panel in FEL mode (next step), open Zadig, choose Options → List all devices, pick USB Device (1f3a:efe8), select WinUSB and click Replace driver. The installer's own USB mode installs its driver by itself.
Add a udev rule, once, so your user can open the panel without root: 
SUBSYSTEM=="usb", ATTR{idVendor}=="1f3a", ATTR{idProduct}=="efe8", MODE="0660", TAG+="uaccess"
SUBSYSTEM=="usb", ATTR{idVendor}=="1f3a", ATTR{idProduct}=="1010", MODE="0660", TAG+="uaccess"
Save it as /etc/udev/rules.d/50-s1.rules, then run sudo udevadm control --reload. If adb runs on this computer, stop it first: adb kill-server.
Nothing to install. Chrome on Android opens the panel directly. Use a USB-C to USB-C data cable, phone to panel.

Step 3 · Back up & install

Keep it plugged in.

Nothing is changed until your panel's own software is safely in this browser. Keep this page open, too.

    Set up the panel

    The panel is restarting with its new software. While it does, check these settings. Wi-Fi and Home Assistant come next, on the panel itself.

    Done

    You're all set

    On the panel, connect to Wi-Fi and sign in to Home Assistant. Home Assistant then finds the panel by itself as an ESPHome device.

    Your backup

    Keep this first backup: it's the only copy of the original software. It is also kept in this browser.
