Understanding Current Events on Your Weenat Sensors

Weenat sensors can signal certain events when an unusual behavior is detected in the field.

These automatic alerts are designed to help you quickly identify a potential issue — whether physical, electronic, or environmental — and address it easily.

In this article, you’ll find: a clear description of each detected event, the likely cause of the problem, and recommendations for effective action. 🙂

• Interrupted broadcast

  The sensor hasn’t sent any data for a while.
  This event occurs when the app doesn’t receive any messages for 24 hours.
  It is different from the event triggered by two consecutive missing data frames (~30 minutes). In that case, the last measurement time appears in red.

  Possible causes:

  • Power outage (empty or disconnected battery)
  • Sensor under dense vegetation cover (especially ground-level sensors): weak signal to relay antennas
  • Network issue (Sigfox, LoRa, or NB-IoT depending on the model)
  • Sensor malfunction or damaged antenna

  Recommended actions:

  • Check battery level; it should be 3.6 V
  • Make sure the antenna is properly in place (machinery, animals...)
  • Pass a magnet under the LED located on the right side of your sensor. This will resynchronise the sensor with its antenna if the connection has been lost. 
  • Contact Customer Support if the issue persists: check network suitability or consider an antenna extension

• Moved sensor

  This event is triggered if the sensor was moved by at least 500 m and a new geolocation message was received.

  Possible cause:

  • The sensor was moved accidentally or intentionally

  Recommended actions:

  • If you moved it, reset it with a magnet on the right side of the casing (solid red LED)
  • If not, check its location and reset it the same way

• Laid down sensor

  The sensor detects an abnormal tilt (it is no longer in an upright position). When this happens, it automatically enters wintering mode and stops taking measurements in order to preserve battery life.

  This event is triggered as soon as the antenna is no longer facing upward.
  However, some sensors, such as PAR sensors or pyranometers, can be installed upside down to measure reflected radiation. In such cases, the sensor incorrectly considers itself to be lying down.

• Blocked spoon

  Applies only to sensors with rain gauges. The spoon is no longer tipping correctly: rainfall is not being counted. The system detects if the spoon hasn't tipped for 4 hours.

  The frequently blocked spoon event is triggered if it occurs at least 10 times, meaning it's a recurring issue.

  Possible causes:

  • Debris (leaves, insects, dirt, nest...) blocking the mechanism
  • Component failure in the tipping spoon system

  Recommended actions:

  In summary: 

  • Gently inspect and clean the spoon (remove the tipping bucket)
  • Also clean the rain gauge bowl
  • If there's a nest, remove it and install the anti-debris grid and spikes
  • Regularly inspect during dense vegetation phase and autumn

The events detected by Weenat sensors are designed to help you maintain the accuracy of your weather and agronomic measurements. They don’t always indicate a serious issue, but they do require your attention to ensure reliable monitoring and avoid data gaps.

Remember to perform regular visual checks on your sensors and ensure their integrity.

Ground-level sensors can be damaged by farm machinery. Make sure they are visibly marked (stakes, nets, PVC tubing) without blocking the antenna.

For any questions, you can contact Weenat Support directly through the app. 🙂
