3.5.2 Table of neighboring devices
Every device saves its connections to other devices in the neighboring devices
table.
For every connection between two devices, the required transmitting power is
determined by means of the 'RSSI' received field strength. The higher the
transmitting power required, the higher the level of energy required and the shorter
the service life of the battery. For this reason, the 'RSSI' signal is optimized to a
target band of -70…-75 dBm at the receiver. This ensures the quality of reception
and keeps battery consumption to a minimum. To achieve this target band, the
neighboring receiver triggers an adjustment to the transmitting power for this
connection.
The transmitting power is displayed in levels 1…10.
Level 1 means a low transmitting power and a long service life for the battery.
Level 10 means maximum transmitting power and a short service life for the
battery.

Indication
Action
Get neighbourhood table
Displays information about local connections to devices.
Device ID
Displays the device ID of the device.
Hop count
Displays the number of radio links for this connection between the device and
the radio gateway.
Recent RSSI [dBm]
The selected device currently receives with the specified received field strengths
from neighboring devices.
Transmission power
Displays the transmitting power of this device in levels from low (1) to
maximum (10).
Channel
The device in this row sends to the selected device on this channel.
In the 868 MHz band, the address is lower than 100.
In the 433 MHz band, the address is higher than 100.
Neighbour rating
Primary: This is a connection frequently used for monitoring the presence of the
device.
Secondary: This connection is primarily used for network maintenance. It may
be used by other devices as a primary connection.
Device address
Displays the group address and the channel address.
