====== Mobile Application ======

Mervis SCADA is available as a **Progressive Web App (PWA)** and provides an experience that is practically identical to the full desktop version.

For the best user experience, we highly recommend **installing the application directly to your device as a PWA**. Installing it removes the browser URL bar, maximizes your screen space for a cleaner native-app look, and allows you to receive push notifications. This modern approach lets you install the app directly from your web browser without needing to visit the Apple App Store or Google Play Store.

To install the app, navigate to **[[https://scada.mervis.info/mobile]]** on your device and follow the specific guide for your platform below:

  * [[en:mervis-scada:60-mobile-app:32-ios|Installation on Apple iOS (iPhone/iPad)]]
  * [[en:mervis-scada:60-mobile-app:31-android|Installation on Android]]
  * [[en:mervis-scada:60-mobile-app:33-windows|Installation on Windows (MS Edge)]]

===== Application Overview & Navigation =====

The mobile app is designed to give you quick access to your data through a logical step-by-step flow. 

==== 1. Login ====

Upon opening the installed PWA, you will be greeted by the login screen. Log in using your standard Mervis SCADA credentials.

//Mobile Login Screen//

==== 2. Project List & Favorites ====

Once logged in, you will see your **Project List**. By default, you can toggle between two tabs at the top of the screen:
  * **All:** Displays every project your account has access to.
  * **Favorites:** Displays only the projects you have explicitly starred for quick access.

==== 3. Project Detail (Table View) ====

Tapping on a project opens the **Project Detail** in a standard table view. This displays all available datapoints, their current values, statuses, and timestamps.

==== 4. Selecting Datapoints ====

To select a datapoint for graphing or bulk actions, use the following gesture:
  - **Tap and hold** your finger on the target datapoint until you feel a brief haptic vibration (a little rumble).
  - **Swipe left or right** across the row to select it. The row will turn **green** to indicate it is selected.
  - To **unselect**, tap and hold the green row, then swipe left or right again.

==== 5. Schemas (Visual Project View) ====

If your project includes visual representations or schematics, you can view the full layout directly on your phone. Tap the **Image Icon** located in the top toolbar to switch from the table view to the Schema view.

==== 6. Alarms ====

Use the **Alarms** tab in the bottom navigation menu to view current triggered alarms, review alarm history, and acknowledge active warnings across your projects just as you would on the desktop.

===== Graph Settings & Customization =====

The blue **Graph Icon** is permanently located in the top toolbar. You can tap this icon at any time to open the graphing interface for your currently selected datapoints.

By default, tapping the graph icon will open a Line graph. Tap the **Settings** menu within the graph view to adjust the parameters. The available settings will dynamically change depending on which graph type you select.

=== Line Graph Settings ===
When using a Line graph, you can adjust the following:
  * **Time span:** Change the duration of the data displayed (e.g., 3 days, 1 week).
  * **Graph type:** Switch your visualization to Bar or Carpet formats.
  * **Multiple Y axes:** Toggle multiple axes on or off for comparing different data scales.
  * **Show points:** Display individual data points along the line.
  * **Connect points:** Choose whether to connect the line across missing data gaps.
  * **Legend:** Choose how the legend is displayed (e.g., Short names).

=== Bar Graph Settings ===
When using a Bar graph, you have specific options for calculating and grouping your data:
  * **Bar range:** Group data by specific intervals (e.g., Day).
  * **Calculation type:** Choose how the data is computed (e.g., Difference with interpolation).
  * **Normalize (100%):** View the bar data as a percentage of a whole.

=== Carpet Graph Settings ===
Carpet graphs offer a streamlined settings menu focused purely on time and layout:
  * **Time span:** Change the duration of the data displayed.
  * **Graph type:** Switch your visualization to Line or Bar formats.
  * **Legend:** Choose how the legend is displayed.

===== Available Graph Types =====

The mobile app supports three distinct graph types. The application fully supports both **portrait** and **landscape** orientations—feel free to rotate your phone at any time for a wider view!

=== Line Graphs ===
Line graphs are perfect for tracking continuous data trends and identifying fluctuations over time (such as temperature changes).

//Line Graph Example//

=== Bar Graphs ===
Bar graphs are ideal for comparing distinct data sets, viewing totals, or analyzing historical averages side-by-side.

//Bar Graph Example//

=== Carpet Graphs ===
Carpet graphs act as heatmaps. They are excellent for visualizing data density and spotting complex patterns across specific times of day over a longer period.

===== Legacy Native Applications =====

> **⚠️ Notice for existing users:**
> Previously, native Mervis SCADA applications were available in the App Store (iOS) and Google Play (Android). These native versions have been **discontinued and removed from the stores**.
>   * **If you already have the native app installed:** It will continue to function normally. You can keep using it, though it will no longer receive updates.
