Alerts That Protect Your Investment

Create custom rules to get advance alerts for the events that most impact your production

Frost

Set your minimum temperature threshold. E.g.: "Alert me if it drops below 2°C" to protect sensitive crops in time.

Strong Wind

Configure your gust limit. E.g.: "Alert if it exceeds 50 km/h" to suspend spraying or protect structures.

Rain

Choose your critical accumulation. E.g.: "Notify if more than 25mm is expected" to reschedule harvests or fieldwork.

Heat Wave

Set heat thresholds per crop. E.g.: "Alert if it exceeds 33°C" to prevent heat stress and plan irrigation.

Storms

Monitor atmospheric instability. E.g.: "Alert on high convective energy" with risk of hail and severe wind.

Irrigation

Detect water deficit and irrigation needs. E.g.: "Alert when the water balance is insufficient for the crop".

You define the thresholds, variables and severity — each field with its own rules

Find answers to the most common questions about Vienor

What is Vienor and how does it work?
Vienor is a weather alert system designed for agriculture. It monitors your fields' weather conditions every 30 minutes and sends automatic push and email alerts when it detects risk conditions such as frost, strong wind, heavy rain, or high temperatures.
What weather data does it use?
We integrate up to 6 global models simultaneously (ECMWF, GFS, YR.no, Tomorrow.io, ICON/DWD and Visual Crossing) with up to 16 days of forecast range. Alerts are checked automatically every 30 minutes.
Can I monitor several fields at once?
Yes, the number of fields is unlimited. Each field is individually georeferenced on the map, with forecasts and alerts specific to its location.
What else does Vienor include besides alerts?
Vienor includes a digital field notebook, satellite NDVI with Sentinel-2 (with 12-month history and a map overlay layer), an hour-by-hour spraying window traffic light, multi-model comparative forecasts, advanced analytics, and on-demand AI reports.
How do I receive alerts?
Alerts are sent via browser or mobile push notifications and by email. You can configure which alert types to receive, the specific threshold, and the channel, according to each field's needs.
Can I customize alert thresholds?
Absolutely. You can create custom rules defining the alert type (frost, wind, rain, heat, storm), the specific threshold, and the severity. For example, you can set a frost alert when the temperature drops below 2°C instead of the default value of 0°C.
Do I need to install anything?
No. Vienor is a progressive web app (PWA) that runs directly from the browser. You can add it to your phone's home screen to use it like a native app, with no need to download anything from an app store.
How does the 30-day free trial work?
Contact our sales team and we'll activate your 30-day free trial of the Pro plan, with full access to every feature and no credit card required. Before it ends, we'll reach out to arrange the continuity of your account.
Is it secure? Who can see my data?
Yes. We implement two-factor authentication (TOTP and WebAuthn passkeys), anti-bot protection with Cloudflare Turnstile, and JWT sessions. Your data is private and only you can access it with your account.
