Monitoring the Wireless Signal
RSSI (Receive Signal Strength Indicator) is a measurement that determines the power of a
received signal.
You can view the received signal strength on the Trend Log object page in dBmV (decibels
relative to one millivolt) and adjust the position of the sensor if your signal is weak. The trend
log table graphically displays the time range and strength of the signal. For more information
about trend logs, see

Value of Signal Strength
The following table outlines signal strength ranges. If the dBm value is high, the signal will be
weaker; if the dBm value is low, the signal will be stronger.
Signal Strength
Description
-40 dBm
Indicates a very strong signal.
EnOcean sensor is likely in close proximity to the O3 Hub.
-60 dBm
Indicates the signal is sufficient enough to communicate
to the O3 Hub. Sufficient for delivery of packets.
-80 dBm
Indicates a weak signal. Packet delivery may be unreliable.
You may need to adjust the position of the sensor and O3
Hub.
