No online Cloud Connector nearby

The sensor can only send data to the cloud if a nearby online Cloud Connector exists.

• Install Cloud Connector near the sensor.
• Conduct Cloud Connector (2nd Gen) troubleshooting.

Service disruption

Cloud service disruptions can impact sensor connectivity.

• Check our Status page and follow the instructions.

Battery tab stuck

If your sensor is having trouble connecting, it may be because the battery tab got stuck inside the battery cavity when it was being removed.

• To check if the battery tab is stuck, first remove the sensor from its bracket using a small screwdriver according to the installation manual. Take out the battery and inspect the sensor cavity carefully. Look for any remaining pieces of the battery tab inside. If you see any debris, gently remove it before reinserting the battery.

Temperature outside the operating range

Sensors may stop reporting data if:

• Temperature for sensors unit is outside the range of -25°C to 50°C (-13°F to 122°F) 
• Humidity is over 90% or condensation is present. The sensor is not designed to operate in condensing environments, and condensation at any RH level is outside the supported operating range.

• Place the sensor within the operating temperature. If the sensor remains offline, it may be permanently damaged and need replacement.

Mechanical damage

The sensor is sealed and robust, but impacts can damage it.

• Inspect the sensor for visible damage. If visible damage and the sensor remains offline, it may be permanently damaged and need replacement.
• Install the sensors according to the installation manual.

Water penetration

The sensor is not waterproof (IP50), so any exposure to water/condensation will cut its lifespan short.

• Dry the sensor thoroughly. If the sensor remains offline, it may be permanently damaged and need replacement

Depleted battery

The sensor needs a working battery to measure temperature and send radio messages. 

• Check the battery level in Studio or API. If depleted, replace the sensor battery according to installation manual.
• Store sensors optimally to ensure a long lifetime.

Regional product incompatibility

DT devices have two versions: EU and US that use different radio frequencies.

• Use EU Cloud Connectors for EU sensors and US Cloud Connectors for US Sensors.

Cloud Connector is out of range

The sensor can only send data robustly to the cloud if a nearby online Cloud Connector exists.

• Install Cloud Connector near the sensor according to best practices
• Conduct Cloud Connector (2nd Gen) troubleshooting

Environmental challenges

The sensor's placement affects signal strength. Metal or glass doors, as well as enclosed spaces with thick walls can weaken connectivity.

• Check the sensor's location and reposition it if needed for better signal. Try repositioning the Cloud Connector closer to the sensors, ensuring a stronger and more stable connection.
• Look for changes like moved Cloud Connectors, new walls, or other obstacles affecting radio communication.

Electromagnetic interference

Strong electromagnetic interference may inhibit radio reception in the sensor or the Cloud Connector, causing intermittent communication loss even with a strong connectivity indication.

• Move the Cloud Connector and/or the sensor away from the source of electromagnetic interference. Typical sources of electrical interference are: RFID access systems, other equipment containing radio transmitters, or faulty electronic equipment.

Wrong placement or orientation

Wrong sensor and magnet placement or orientation can affect the readings.

• Place the magnet on the same side as the indicator mark. They should be center-aligned.
• Ensure the gap is less than 30mm (1.2 inches).
• The installation surface can have a substantial impact on the magnet range - e.g., if installing on metal, the metal will absorb some of the magnetic field, which will make the detection range shorter and reduce the required gap to 15mm (0.6 inches).

Impact of electrical equipment

If the sensor reports false or inconsistent detections, it may be affected by electromagnetic interference (EMI). This can happen when the sensor is installed too close to devices like fluorescent lights, motors, or large electrical machinery, which can disrupt its measurement.

• Reposition the sensor. Make sure to mount the sensor away from any possible electromagnetic interference.
