1 Network properties
Produal Proxima® wireless network is based on Lumenradio MIRA platform that provides a wireless
mesh network with unprecedented scalability and reliability. The Mira network is a self-healing multi-
hop network system that operate on the worldwide license-free 2,4 GHz ISM band. With patented
Future-Proof Coexistence Connectivity (FPCC) technologies we enable connectivity that can safely co-
exist along other wireless technologies, not being interfered or causing interference.
Important: The network uses 2,4 GHz frequency for communication. The frequency is an
ISM frequency band that can be used worldwide without any licence fees. If you are not sure
about the permissions to use this frequency in your country, contact your local authority for
more information.
Produal Proxima® WBU base unit supports up to 100 transmitters and separate repeaters are not
needed. The transmitters work as repeaters without any special configuration.
Only Wireless Produal Proxima® MESH 2,4 GHz products are compatible with the network.
MIRA is used for wireless communication between transmitters and base unit. Produal MyTool® can’t
communicate with wireless devices using MIRA. Bluetooth is used for communication between Produal
MyTool® and wireless devices. The Bluetooth communication can be active with only one device at a
time.
Note: The wireless devices can use only one communication protocol at a time. The device
is disconnected from the MIRA network when the Bluetooth is activated.
The wireless devices also support Bluetooth beacon messages. Beacon messages are one-way
messages from transmitters and base unit to Produal MyTool® application. These messages are used
to send information to application when monitoring or debugging the network. Signal scanner also
uses these beacon messages to calculate signal strength between device and application. The beacon
messages can be used also when the device is connected to a MIRA network.
Base unit sends the beacon messages continuously. The transmitter beacon messages can be activated
manually and the messages are active for one hour in following situations.
• During the transmitter installation to network, after the MIRA communication is activated.

2 Wireless network functions
2.1 Power consumption
The wireless devices can be powered with a battery or with wired power supply.
The battery powered transmitters measure the battery level two times a day. The battery level has six
possible values: 99, 90, 50, 10, 5 and 1 %. The value means that the battery level is at least the given
value, not the absolute value.
The battery life depends on the installation environment, used polling interval and firmware updates.
2.2 Average groups
The data collected from the transmitters can be arranged into five average groups. One average group
can be represent one measured property, such as temperature, humidity, carbon dioxide, etc. One
transmitter can be in several groups and one group can include only one measured property. The
average groups can be defined using Produal MyTool®.
The average value is calculated continuously from the latest available values. The highest and lowest
measurements are also available for the group.
Measurements that exceed or fall below a particular subset can be dropped out from the calculation.
For example, you can set that under 15 ºC and over 30 ºC measurements are dropped from the
average calculation. These limits are only available for temperature values.
2.3 Alarms
You can read the alarms based on the wireless network information from the base unit Modbus
registers. The alarms always include the device ID that is sending the alarm. The following alarms are
available.
• Battery level alarm. You can set the battery level that causes an alarm.
• Missing transmitter alarm.
• Measurement value alarm. You can set the measurement value limits that define the normal values.
An alarm is caused when the value drops under the low limit or rises over the high limit.
2.4 Input register cloning
With the input register cloning you can group the transmitter information to a smaller Modbus register
range. This enables the read multiple values Modbus function. The function can be used for reading
temperature measurements from the whole network, for example. You can set up to ten cloned
register value sets (0...9) that can be read from the same input register range.
The cloned input register range is from 18X00 to 18X99 according to the transmitter ID. The X is the
set number (0...9). The cloned registers are defined in the holding registers 18000...18009.
For example if you want to read a temperature value from the transmitter with ID 27, you can read
the values from the input register 18026. The cloned register set 0 is for temperature by default. The
original register for the transmitter temperature is 22651.
2.5 Value over bus (VOB)
The data can be transmitted in two directions, which allows also external values to be viewed on the
transmitters' displays. The base station has writeable Modbus registers, where the data can be written
and then send to the transmitters. The function is useful for example if BMS information must be
viewed on a transmitter display.

Two transmitter specific values can be shown on the displays. Also one global value (e.g. outdoor
temperature) can be shown on all displays in the network. The used value type is set to base unit
settings by using Produal MyTool®.
Note: The transmitter specific value type must be the same for all transmitters.

The VOB data is updated to transmitters in specific messages and the interval of these messages is
fixed to the network size. The update frequency can be calculated by using the following formula:
network size x 5 s. For example, if there are 10 transmitters and a base unit in the network, the
update interval is approximately 55 s.

2.6 Firmware updates
The base unit firmware can be updated only locally using Produal MyTool®.
The transmitter firmware updates can be done locally or by using Firmware Over The Air (FOTA)
function.
The FOTA function updates the devices over the wireless network. The FOTA firmware update process
can take up from few minutes to several hours depending on the network size. The base unit updates
two devices at a time and then moves to the next devices until the whole network is updated to the
latest firmware version. The update process starts from the closest transmitter in the network.
Note: The FOTA function requires more power than the regular transmitter functioning.
Therefore the FOTA updates should be planned carefully in battery powered network. The
transmitter is not updated if the battery level is too low (under 10 %).
Note: The whole network is restarted after all devices are updated.
2.7 Measurement data sending interval
The measurement data can be read from the transmitters based on the base unit polling, with fixed
interval and with a Change of Value (COV) function.
Transmitters send the measurement information to the base unit according to the base unit polling
interval. The base unit requests the measurement information according to this interval even if other
data sending methods are also selected. The interval can be set to 60...65535 s (1 min...18 h).
In COV mode, the transmitter sends the measurement data also when the data changes. If the value
has changed more than the given hysteresis, this data is sent to the base station. The measurement is
continuous in transmitters with wired power supply. In battery powered transmitters, the measurement
is activated according to the network activity interval. The network activity interval can be set to
10...65535 s.
Note: Short interval may significantly shorten the battery life.
Note: The COV mode may significantly shorten the battery life if the hysteresis is set to
very low value.
If the fixed interval is selected in the transmitter, the measurement data is sent to the base unit also
with this interval. The interval can be set to 30...65535 s.
Note: Short interval may significantly shorten the battery life.
