Cloud Connector Ethernet network requirements
If high-quality Ethernet access to the internet is available, the Cloud Connector would bene#t from being connected via this vs.
the built-in cellular modem (if available).
Please make sure that DHCP is activated on the Ethernet network; the Cloud Connector will ask for an IP address automatically
when connected.
Avoiding data loss
To operate reliably and avoid data loss, sensors require at least one Cloud Connector that is connected to the DT Cloud and
within range of the sensors.
To reduce chances of lost data packets to a minimum, please ensure:
The sensor will perform multiple attempts at delivering a reading, including switching to high energy boost mode for an
increased range. If none of these retry attempts get through, the data point will be lost.
Troubleshooting
Sensor not reporting
Too much boost mode traf!c
Cellular modem latency is generally higher than land-based cable access.
Cellular signal strength is an additional factor that can in"uence the robustness
The Cloud Connector will fall back to cellular if the Ethernet provided drops
Connect Cloud Connectors to an uninterrupted power supply, allowing them to operate in case of a power outage.
Make sure that Cloud Connectors with a built-in cellular modem is placed at a location with su$cient cellular coverage
even if the Cloud Connector normally operates on Ethernet. This will allow the Cloud Connector to fall back to using
cellular connectivity in case of network issues.
Have each sensor within reach of at least two Cloud Connectors. This allows a secondary Cloud Connector to receive
data from the sensor in case of packet loss or loss of an entire Cloud Connector.
Bring a sensor close to Cloud Connector and see if it will start reporting. It may take several hours before the sensor will
automatically detect and reconnect to the network if it has been completely o&ine for an extended period of time
Use the Cloud Connector activity mode to verify if the sensor is transmitting. Go to www.d21s.com/help to learn how to
initiate the activity monitor.
If caused by low signal
Add Cloud Connectors
If possible move sensor into line-of-sight or similar better placement
Move existing Cloud Connector - e.g. middle-of-the room, above the ceiling.
If caused by other issues
