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:

• Installation on Apple iOS (iPhone/iPad)
• Installation on Android
• Installation on Windows (MS Edge)

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

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

Mobile Login Screen

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.

Favorites Tab

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

Project Detail Table View

To select a datapoint for graphing or bulk actions, use the following gesture:

1. Tap and hold your finger on the target datapoint until you feel a brief haptic vibration (a little rumble).
2. Swipe left or right across the row to select it. The row will turn green to indicate it is selected.
3. To unselect, tap and hold the green row, then swipe left or right again.

Selected datapoints highlighted in green

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.

Full Project Schema View

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.

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.

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).

Line 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.

Bar 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.

Carpet Graph Settings

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

Line Graph Example

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

Bar Graph Example

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.

⚠️ 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.
* If you uninstall the app or switch phones: You will not be able to find the app in the store again. You must switch to the new Progressive Web App (PWA) linked above.
