Add new readings in just a few clicks

For gauges with manual reading, simply scan the QR code to instantly access the gauge history and add a new reading. You can:

Enter the reading manually,
Add one or several photos,
Fill in a detailed comment,
Automatically record temperature and humidity thanks to the smartphone’s geolocation.

All the useful information is centralised in one place, simply and quickly.

A unique feature: automatic reading (G1, G1.1, G1.2)

With compatible gauges, Saugnac.app offers automatic reading of the measurement, performed using the smartphone camera. In just a few seconds:

the gauge is recognised,
the cursor position is detected,
the reading is recorded automatically.

A considerable time saving and the assurance of more reliable readings, even when several operators work on the same site. If you encounter any difficulty, feel free to consult our FAQ: it brings together the main usage tips and solutions to common issues.

Add readings without an account (with approval)

Do you need a third party (client, contractor, tenant, building caretaker, etc.) to take a reading, but they don’t have a Saugnac.app account? Simply enable the “Readings without account” option on your gauge. The third party can then submit a reading to you, taken using automatic reading. All you need to do is approve it from your account. Ideal for shared monitoring, remote sites or one-off interventions.

Customise your charts

The application automatically generates clear, easy-to-read charts, but you can go further:

adjust the scale,
display or hide certain types of data,
include or exclude the impact of thermal expansion,
download the resulting image.

A presentation tailored to every situation, ready to be used in a report or expert assessment.

Set alert thresholds

Configure your own alert thresholds to be notified as soon as a crack evolves abnormally. The application automatically warns you if a reading exceeds the defined threshold. You can also set up a distribution list of up to 5 people, so that alerts are sent simultaneously to your colleagues, partners or clients. Each person receives the notification instantly, which makes shared monitoring and quick decision-making easier. Alerts thus allow you to:

immediately detect significant movement,
notify the teams involved,
respond quickly in the event of abnormal evolution,
secure monitoring even when multiple stakeholders are involved.

Share data in one click / Send a report

Would you like to share the situation with an expert, a client or a colleague? In one click, generate a read-only access link to view the data and charts. The recipient can access the full history without needing an account, which considerably simplifies teamwork. And above all, the shared link always stays up to date. Each new reading added will appear automatically, without ever needing to send a new link.

Download your data

All your readings can be exported by gauge or by folder (location):

in Excel format,
in CSV format,
or as a ZIP file with all the data and time-stamped photos.

This way, you keep a complete archive, compatible with your in-house tools, expert reports or technical files.

Modify your sensor configuration remotely

For wireless sensors, you can adjust the measurement frequency and transmission frequency without travelling on site. This feature allows you to adapt the instrumentation to changes in context.

Reuse your sensor on another site

Once a monitoring campaign is complete, simply archive the data:

the history remains saved,
the sensor can be associated with a new site by adding it,
a new monitoring cycle can start cleanly.

Receive battery alerts

For wireless gauges, the application automatically informs you when the battery is reaching the end of its life. You can then plan for replacement without interrupting monitoring.

Extend your subscription in 2 clicks

Wireless gauges require a network subscription to transmit data. From the application, you can extend this subscription in just a few seconds, with no complex steps or additional contact required.
