Battery Life
The sensor uses a lithium non-rechargeable battery, capable of an estimated 200,000+ messages.
Note: Refer to the Sensor Battery Estimator.xlsx spreadsheet on the on the sensor's product page for specific
battery life estimates:
https://www.multitech.com/products/sensors
Battery life depends on the number of transmissions per day. Power required for a message transmission is greater
than the “sleep current” for high power radio technologies (e.g, LoRaWAN).
Different battery types deplete over time with different voltage profiles; a lithium battery maintains high voltage
for the life of the battery with a rapid drop near the end of life, and an alkaline battery has gradual reduction in
voltage over time. Radio Bridge devices are shipped with lithium batteries, which are the recommended
replacement type.
Recommended battery: Panasonic CR123/A
Battery life estimates in the online spreadsheet assume room temperature, meaning temperatures near the
maximum and minimum ratings negatively impact battery life. Battery voltage lowers in cold temperatures, and
internal circuitry needs a minimum voltage to operate properly.
Note: Battery life will be reduced in cold environments leading to possible device shut down.
The battery voltage is reported by the supervisory messages and a low battery indicator. See the section on
Message Protocol for details.

COMMON MESSAGES
Door Window Sensor User Guide 11
Chapter 4 – Common Messages
Common Messages
This chapter defines the protocol and message definitions common to all Reveal wireless sensors. Common
messages include basic error messages, tamper, supervisory, link quality, and downlink acknowledgments. Sensor
specific messages are in the Sensor Specific Messages chapter.
Message Protocol
This section defines the protocol and message definitions for the device.
Note: MultiTech provides a web-based console at console.radiobridge.com for configuring and monitoring
devices. We recommend using this console rather than the protocols defined in this section.
If not using the console, use this topic to configure the device through downlink messages and decode the device
data.
Uplink Messages
The uplink messages (sensor to web application) have the following structure.
Item Size Description
Protocol Version 4 bits A constant 1, provides extensibility to the specific format of a message type.
Packet Count 4 bits A sequential number starting at 0 for the first message sent from the sensor to
the cloud. It increments by one for each subsequent message. When it reaches
0xF (15 decimal), it wraps back to 0. Packet count helps identify when a message
is lost. For example, if the packet count goes 2,4 instead of 2,3,4, it indicates a
message has been lost. It can also help identify out-of-order or duplicate
messages.
Message Type 1 byte Byte format is 8 bits, with 256 combinations possible.
Message Payload 0-7 bytes Each message type has between 0 and 8 bytes of payload data specific to the
sensor. Refer to the following table for payload information.
Message Payload Description
0x00 5-byte reset code Device has reset. The reset cause is represented in the 5-byte
reset code payload.
0x01 >3 (9) Daily supervisory message (1-2 per day). The 3-byte payload
contains current sensor status. Refer to Supervisory Message
0x01for payload details.
0x02 1-byte event A tamper event has occurred. Refer to Tamper Message 0x02for
details.
-- Sensor event Sensor events are defined in the Sensor Specific Messages
chapter.

COMMON MESSAGES
Door Window Sensor User Guide 13
Supervisory Message 0x01
Wireless sensors periodically send a supervisory message so the backend system can verify the device is still alive
and report error conditions. The supervisory message payload include current sensor status.
You can also trigger a supervisory message. To do this:
Place a magnet near the triangular notch on the side of the sensor.
The following table shows the supervisory message payload:
Bytes Description
0 Supervisory error codes as follows:
Bits Description
7:5 Not used.
4 Tamper detected since last reset.
3 Current tamper state.
2 Error with last downlink.
1 Battery low (under 2.8v).
0 Radio communication error, communication with the integrated radio failed and the
device was reset.
1 Current sensor state, 1-byte. This is device specific, refer Sensor Specific Messages chapter for details.
For other devices, use the periodic reporting feature.
2 Battery level is a two-digit battery voltage. For example, if the battery voltage is 2.9V, byte 2 would be
0x29.
3-6 Extended sensor state, 4-bytes. Allows sensors with higher precision or multiple values to report
during a supervisory event. For other devices, use the periodic reporting feature.
7-8 Event accumulation count is the number of sensor events since the last supervisory message. To
improve battery life, can be used with the Disable all sensor events setting so only an event total is
reported during a supervisory message, individual events are not reported as they occur. This feature
is available in firmware v2.0 and beyond.
Tamper Message 0x02
A sensor sends a message when the tamper switch has been opened or closed through either an enclosure tamper
or a wall mount tamper. The tamper message contains a 1-byte payload as shown in the following table.

Radio Config
The following table shows the radio config byte definition.
Note: Available in firmware version 1.4 or newer.
Bits Description
7 Not used (reserved)
6 Enable duty cycle requirement. LoRaWAN EU868 only. To enforce the EU868 band duty cycle
requirements, enable before production deployment. Default is disabled. Available in firmware
2.2.1 or later.
5:2 Uplink retries. LoRaWAN only. The range for uplink retries is 1-8 for confirmed messages (ACK
required) and does not apply to unconfirmed messages. Default 0 (leave unchanged). Available in
firmware v1.4 and above.
1 Use unconfirmed messages. LoRaWAN only. If set to use the unconfirmed messages bit, the sensor
does not look for an ACK from the network server. Default is 1 (unconfirmed messages, no ACK
required). EU sensors can’t use confirmed messages, setting this bit to 0 on an EU device causes an
error. Available in firmware v1.4 and above.
0 Disable Adaptive Data Rate (ADR). LoRaWAN only. To enable ADR, set to 0. To disable ADR, set to
1. Default is 0 (enabled). Available in firmware v1.3 and above.
Important: The duty cycle bit must be set for production deployments in the EU868 band.
Supervisory Period
The general configuration command’s supervisory period controls the time between supervisory messages as
defined in the following table.
Bit 7 Bits 6:0
0 Period defined in hours (1-127 hours). Available in firmware v1.3 and above.
1 Period defined in minutes (1-127 minutes) Available in firmware v1.3 and above.
For example, to receive a report every 4 hours, set Byte 1 to 0x04. To receive a periodic report every 15 minutes,
set Byte 1 to 0x8f.
Sampling Rate
Sampling rate controls the frequency at which devices wake from low power sleep mode to check the sensor state.
Some sensors require very little power to check the state and need to react quickly. Other sensors can be sampled
at a lower rate, such 30-second or 30-minute intervals. Increasing the time between samples increases battery life.
Refer to the Battery Estimator on the Radio Bridge site for battery life estimates relative to sampling rate:
https://radiobridge.com/documents/Sensor%20Battery%20Estimator.xlsx
A value of 0 in this field leaves the sampling rate at the current value. Use the following table to determine the
sampling rate if the value is not zero.
Note: Sampling period only applies to sensors that take measurements like temperature and tilt, it does not
apply to sensors with binary inputs such as door/window sensors or push buttons.
This feature is available in firmware v2.0 and above.

COMMON MESSAGES
16 Door Window Sensor User Guide
Bit 7:6 Bits 5:0
00 Sampling period defined in increments of 250ms (0.25-15 seconds).
01 Sampling period defined in increments of seconds (1-63 seconds).
10 Sampling period defined in increments of minutes (1-63 minutes).
11 Sampling period defined in increments of hours (1-63 hours).

Use this command for advanced configuration parameters that apply to all sensor types. The advanced
configuration command is defined in the following table.
Byte Description
0x01 Port number (LoRaWAN only)
0x02 Link quality check period (LoRaWAN only)
Port Number
For LoRAWAN devices only. Byte 0x01 of the advanced configuration command changes the uplink port per the
LoRaWAN protocol. The default port is 2, and a value of 0 in this field means to leave it at the default.
This feature is available in firmware v1.4 and above.
Link Quality Check Period
For LoRaWAN devices only. Setting this register causes the device to ping the network server periodically with a
requested ack. Typically used with unconfirmed messages, this feature creates a periodic confirmed message and
looks for the ack to ensure the device is still connected.
The following table shows this byte’s encoded bit definitions.
Available in firmware v2.0 and above.
Bit 7 Bits 6:0
0 Period defined in hours (1-127 hours).
1 Period defined in minutes (60-127
minutes)

COMMON MESSAGES

SENSOR-SPECIFIC MESSAGES
18 Door Window Sensor User Guide
Chapter 5 – Sensor-Specific Messages
Uplink Messages
The uplink message (sensor to web application) specific to the sensor is defined in following table. The common
uplink messages are not included in this section (see common messages document).
Event Payload Description
0x00 Sensor is “closed” meaning that the magnet is present
0x01 Sensor is “open” meaning that no magnet is present
Downlink Messages
The downlink message (web application to sensor) specific to the sensor configuration is defined in following table.
The common downlink messages are not included in this section (see common messages document).
Event Payload Description
0 Disable events (see the table Disable Events Bit
Definitions)
1-2 Open hold time
3-4 Close hold time
The hold times are 16-bit values that represent the amount of time the sensor must be held in a particular position
(open or closed) before a message is sent. An example of how this is would be used when monitoring a door to a
refrigeration unit. When the door is open or shut with, say, 1 minute, no alerts are sent. When the door is left
open for a longer period indicating that it was left open, an alert can be sent.
The hold time values range from 1-65535 and are represented in 250ms increments. This gives the hold times a
range of 250 milliseconds – 4.5 hours. If the hold time is 0, the feature is disabled and an alert will be sent any
time the state changes.
The table below describes the disable bit definitions which can selectively disable alerts for one orientation or
another.
Bits Description
7:2 Not used
1 Disable close events. Set to disable, clear to enable.
0 Disable open events. Set to disable, clear to enable.
Note: Note that downlink messages for this door/window sensor are not sent after supervisory messages unlike
other sensors as defined in the Common Messages document. For security purposes, the sensor can only be
configured after a reset or tamper-open event.
