In our diagnosis, we will distinguish:
Sensors that no longer receive data (even though they were previously working)
Sensors that receive data irregularly or with large gaps
This is what we will cover in this article 🤓.
My sensor no longer receives data (even though it was working)
Observed behavior
The sensor has suddenly stopped transmitting, although it had been sending information correctly until now.
Possible causes and actions/observations
1. Desynchronization with the relay antenna
🔧 Reset the sensor by passing a magnet over the LED on the right side of the case to help it resynchronize (check if the LED lights up and data starts transmitting again—usually within 15–30 minutes).
2. Low battery: check the age of the sensor or the battery in the app (in the sensor settings*)
🔧 If the sensor is more than 2 years old, consider replacing the battery.
3. Obstacle affecting data reception
Vegetation cover, contact with a metal area, another antenna, sensor moved near a high obstacle, or a magnetic field can interfere with communication.
🔧 Move the sensor to an area away from these obstacles or install/order an antenna extension.
4. Sensor damage (antenna or casing damaged) :
🔧 Contact Support to arrange a service request.
If no improvement is observed despite these actions:
Contact Support using the form below (or support@weenat.com), providing:
The reference(s) of the sensor(s)
Photos of the installation for environmental analysis
Actions already performed
These details will help us provide a more effective pre-diagnosis.
My sensor’s transmission quality is poor
Observed behavior
The transmission quality is below 50%, meaning the sensor will send 2 messages per hour instead of 4 (on average) and/or transmissions are very irregular (with interruptions of an hour or more).
Possible causes and actions/observations
Network coverage: The area may have poor coverage. You can check using Sigfox network maps (for distributors) or Orange coverage. For cellular networks, verify with your smartphone that the area has at least 4G coverage.
🔧 Move the sensor to a better-covered area and/or improve reception using an antenna extension (outside of a “white zone”).
🔧 Consider changing the network: This can be done independently for sensors starting with Wxxxxxx to switch between LoRa ↔ Sigfox (see procedure below). For other sensors or switching to the cellular network, please contact Support.
Obstacle affecting data reception: lThe antenna must be tightly secured and unobstructed, not under vegetation, in contact with metal or another antenna (keep at least 20 cm between sensors), near a high obstacle, or near a magnetic field.
🔧 Move the sensor to an area away from these obstacles.
🔧 Install an antenna extension (contact Support if you don’t have one).
