No online Cloud Connector nearby

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

Service disruption

Cloud service disruptions can impact sensor connectivity.

Temperature outside the operating range

Sensors may stop reporting data if the temperature is outside the range of -40°C to 85°C (40°F to 185°F) or if 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.

Exposure to magnetism

Magnetic fields can drain the battery and cause unresponsiveness for the sensor.

Mechanical damage

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

Water penetration

The sensor is waterproof (IP68), but prolonged exposure to water/condensation may shorten its lifespan, especially in high temperatures.

The sensor is placed on metal

The sensor has a small antenna that will be affected if the sensor is placed on a metal surface.

Depleted battery

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

Regional product incompatibility

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

Cloud Connector is out of range

The sensor can only send data robustly to the cloud if a nearby online Cloud Connector exists. Otherwise, it will enter Boost mode (boost icon) or sporadically go offline.

• 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.

Near end-of-life

A low sensor battery may cause it to go offline and online intermittently.

• Contact Support if other causes have been ruled out.

The sensor is exposed to water or condensation

Small water droplets reaching the inside of the sensor housing may trigger the touch sensor and cause false touch events or prevent touch events from being detected.

• Remove the sensor from the suspected wet or humid spot and let it dry thoroughly before testing it again.
• If the sensor is still not operational or not working as expected, reach out to DT Support for further help.

Mechanical damage or obstruction

If the button surface is stuck or damaged, it may prevent touch events from being correctly detected.

• Gently clean the sensor surface and around the edges to avoid damage. Cleaning along the edges (between the button and the rims) may help release the sensor if it is stuck. Instructions for cleaning the sensor can be found here: How do I clean the sensors?
• If the sensor still doesn't respond as it should, it might be a sign of damage and needs replacing. Reach out to Support for confirmation.

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 capacitive sensing.

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