+# Supported Hardware
+This document contains an incomplete list of device and display hardware combinations that have already been tested.
+
+The [release](https://github.com/leukipp/touchkio/releases) page has builds exclusively for **arm64** and **x64**, but custom builds for other architectures can be made (see [development](https://github.com/leukipp/touchkio?tab=readme-ov-file#development)), allowing the application to operate on any hardware.
+At least the **minimal** features, such as displaying a **kiosk window** (which doesn't necessarily need to be Home Assistant) will work.
+
+## Hardware
+If you are running Linux with a graphical user interface (Wayland or X11), you should be well equipped to use the application. Additionally, any single board computer (SBC) clones of the Raspberry Pi that operate on Raspberry Pi OS **(64-bit)** are likely to function as well.

 The [install.sh](https://github.com/leukipp/touchkio/blob/main/install.sh) script mentioned above performs the following tasks (and you just have to do it manually):

+  - Others (**zip**): Extract the archive and run the binary, e.g:  `unzip touchkio-linux-x64-1.x.x.zip && cd touchkio-linux-x64 && ./touchkio --setup`
 - If you just want to load a Home Assistant dashboard without further control you are good to go, e.g: `touchkio --web-url=https://demo.home-assistant.io`
+  - The `--web-url` doesn't necessarily need to be a Home Assistant url, any kind of website can be shown in kiosk mode.

+If you access your device over SSH, make sure to export the display variables so the kiosk application can launch in the desktop environment.
+```bash
+export DISPLAY=":0"
+export WAYLAND_DISPLAY="wayland-0"
+```
+To make this permanent, consider adding the export variables into the `~/.bashrc` file.

+### Extensions
+
+<details><summary>You probably won't need this.</summary><div></br>
+
+Incorporating custom extensions and external hardware (like motion sensors, ultrasonic sensors, cameras, relays and switches) via **Raspberry Pi's GPIO/USB** involves several steps. 
+While using external sensors that directly integrate with Home Assistant and by utilizing automation's to interact with **TouchKio via MQTT** is generally easier and **recommended**, here's a rough guide on how to proceed with custom hardware integration:
+
+1. **Install Node.js library**: Use Yarn to add a library that can interact with your hardware (GPIO, USB, etc.):
+    ```bash
+    yarn add [package-name]
+    ```
+    This will update the `package.json` file with the required dependencies.
+
+2. **Import the library**: Open the `hardware.js` file and import the library using:
+    ```javascript
+    const package = require("[package-name]");
+    ```
+    Then implement your custom methods and logic to handle the hardware. Don't forget to export the methods at the end of the file:
+    ```javascript
+    module.exports = { ... };
+    ```
+
+3. **Expose sensors via MQTT**: If you want to publish sensor data through MQTT, implement some init and update methods in the `integration.js` file:
+    ```javascript
+    const initCustomSensor = (client) => { ... }
+    const updateCustomSensor = (client) => { ... }
+    ```
+    To get started have a look at the existing methods. Don't forget to call the custom sensor initialization method inside the global init method, where the MQTT connection is established:
+    ```javascript
+    const init = async (args) => { ... }
+    ```
+    From there, you will need to further refine your code by tinkering with sensor updates. This can be achieved through either periodic update calls or event based triggers.

 ### The nitty gritty

-To enable **write access** to the `/sys/class/backlight/10-0045/bl_power` and `/sys/class/backlight/10-0045/brightness` files, you need to set up a **udev rule**.
+The Raspberry Pi's **build-in on-screen keyboard** named `squeekboard` (it squeaks because some *Rust* got inside), is specifically designed for Wayland environments and features a **D-Bus interface** that allows applications to show or hide the keyboard as needed.
-This is done within the `install.sh` script, which also creates a `.service` file.
+The kiosk application interacts with squeekboard via the `D-Bus` object path `/sm/puri/OSK0`, enabling the keyboard to be hidden or shown based on **MQTT** user input or system events. 
-While creating a service file is optional, it's highly recommended if you want your Raspberry Pi to automatically boot into kiosk mode.
 
 The Raspberry Pi's **build-in screen blanking** function uses the command `swayidle -w timeout 600 'wlopm --off \*' resume 'wlopm --on \*' &` inside `~/.config/labwc/autostart` to blank the screen after **10 minutes**.
 The `wlopm --off \*` command changes the `bl_power` value to **4**, when setting the value to **0** the screen will turn on again.

 However, I found that it **never triggered** for the `bl_power` file.
 Although the file content changes, none of the filesystem listeners where fired.
 This could be due to `swayidle`/`wlopm` performing write actions at a deeper level that are not detectable by file listeners.
-As a result, I went for a **polling solution**, checking the state of both files every **500 milliseconds** for any changes.
+As a result, I went for a **polling solution**, checking the state of the file **every second** for any changes.
 While I understand this is not ideal, it's necessary to ensure proper functionality.
 
+The display power status and brightness can be adjusted via the MQTT integration.
+**Support** for changing the power status on **DSI and HDMI** displays is achieved by checking for connected screens in `/sys/class/drm/*/status`.
+Support for changing the brightness of connected display is implemented by using `/sys/class/backlight/*/brightness`.
+In cases where no supported backlight device is found, the Home Assistant light entity will only show an on/off switch without brightness control.
+
 Keep in mind that default arguments are stored as plain text in `~/.config/touchkio/Arguments.json`.
 This file also includes the **MQTT user password**, which is somewhat obfuscated/encrypted, but in a way that it could be easily reverse engineered.
 Implementing stronger **security measures** would complicate the setup process and could discourage some users from configuring the application properly.
 When using the kiosk application without initializing the default arguments, you will need to provide them with every command.
 This means that the password may be stored as plain text in various files, such as `touchkio.service`, `~/.bash_history`, etc.
 
-To resolve the issue where the first **touch** on a **turned-off screen** triggers a **click event** (potentially activating Home Assistant actions), I implemented a workaround.

-When the screen **turns off**, I remove **focus** from the kiosk window.
+When the screen **turns off** the **focus** is removed from the kiosk window.
 This way, the first click only turns the screen on and focuses the window, allowing subsequent clicks to work as expected.
 
-Additionally, to address the problem that scrolling on the Raspberry Pi only works with the **web browser scrollbar** on the right, I configured the Electron app to **simulate a touch device** using `Emulation.setEmitTouchEventsForMouse`.
+Additionally, to address the problem that scrolling only works with the **web browser scrollbar** on the right, the application is configured to **simulate a touch device** using `Emulation.setEmitTouchEventsForMouse`.
 This adjustment provides a user experience similar to that of a proper mobile device.
 
-Electron apps are known to be **resource intensive** due to their architecture and the inclusion of a full web browser environment. If you just run the kiosk application without other heavy loads, everything should run smoothly.

 ## Issues
-- Currently, only the Raspberry Pi 5 in combination with the new touch display 2 supports the MQTT integration.
+Please have a look into the [hardware](https://github.com/leukipp/touchkio/blob/main/HARDWARE.md) documentation if you ran into any issues. 
-  - Other variations, such as Raspberry Pi 4 or Raspberry Pi 5 with touch display 1, could likely be added, but this will require additional testing and contributions via pull requests.
+
-- You can use Raspberry Pi's build-in screen blanking functionality, however, if the screen is turned on through Home Assistant after being automatically turned off, it will remain on indefinitely.
+**Minimal features** are designed to run on any system without issues:
-  - It's recommended to either use the built-in screen blanking feature or implement a Home Assistant automation (e.g., presence detection) to manage the screen status.
+- A webview kiosk window launched in fullscreen mode and loading the specified `--web-url` website should not cause any problems.
-- Hyperlinks that redirect the browser away from the main window are intentionally disabled.
+
-  - This decision was made to maintain a clean design, as navigation buttons to move back and forth between different sites were not included.
+**Extended features** become available when the `--mqtt-*` arguments are provided and the hardware is supported:
-- On the Raspberry Pi terminal you may see some *ERROR:gbm_wrapper.cc* messages.
+- If your hardware is not fully compatible there should be no crashes, but you may miss some sensors.
+    - On some Debian based systems (e.g. Ubuntu GNOME), the display status control may only be available when using X11.
+- The following commands are currently implemented to modify the display status.
+  - `wlopm --[on]/[off] *` (Raspberry Pi OS, Wayland) 
+  - `kscreen-doctor --dpms [on]/[off]` (Debian KDE, Wayland) 
+  - `xset dpms force [on]/[off]` (Generic, X11) 
+
+**Known Issues** that are by-design or for which there isn't a solution so far:
+- You can use Raspberry Pi's build-in [screen blanking](https://www.raspberrypi.com/documentation/computers/configuration.html#screen-blanking-3) functionality, however, if the screen is turned on through Home Assistant after being automatically turned off, it will remain on indefinitely.
+  - It's recommended to either use the built-in screen blanking feature or implement a Home Assistant automation (e.g. presence detection) to manage the screen status.
+- When using a Raspberry Pi, the on-screen keyboard doesn't automatically pop-out when entering a text field inside the webview.
+  - As a current [workaround](https://github.com/leukipp/touchkio/issues/4) you can use the side [widget](https://github.com/leukipp/touchkio/issues/16) to toggle the keyboard visibility.
+- Certain commands from the MQTT integration may require elevated privileges to work correctly.
+  - Ensure that your local user has the [necessary permissions](https://github.com/leukipp/touchkio/issues/39) to run `sudo` without being prompted for a password. 
+- On the terminal you may see some *ERROR:gbm_wrapper.cc* messages.
   -  This appears to be a [known issue](https://github.com/electron/electron/issues/42322) that currently lacks a fix, but the webview still works.
