DSB45 Water Sensor

This describes the Z-Wave device DSB45, manufactured by AEON Labs with the thing type UID of aeon_dsb45_00_000.

DSB45 product image

The DSB45 supports routing. This allows the device to communicate using other routing enabled devices as intermediate routers. This device is unable to participate in the routing of data from other devices.

The DSB45 does not permanently listen for messages sent from the controller - it will periodically wake up automatically to check if the controller has messages to send, but will sleep most of the time to conserve battery life. The wakeup period can be configured in the user interface - it is advisable not to make this too short as it will impact battery life - a reasonable compromise is 1 hour. The wakeup period does not impact the devices ability to report events or sensor data. The device can be manually woken with a button press on the device as described below - note that triggering a device to send an event is not the same as a wakeup notification, and this will not allow the controller to communicate with the device.

Overview

Wakeup Information

To wake up the sensor, don’t push the wake up button, as it does nothing. Instead, tap the zwave button once. Use wake up button to put back to sleep immediately.

Press WakeUp button or hold z-wave button

The Water Sensor will keep waking up for 8 seconds after sending the wake up notification command.
The Water Sensor will keep waking up for 8 seconds to waiting for the next command after receiving a command.
The Water Sensor will be woken up for 10 minutes when power is on (configurable).
There are 3 ways to exit the Wake up 10 minutes state:

  1. Triple click the tamper switch, and the Water Sensor will sleep immediately
  2. Receive the “Wake up no more information CC” command , sleep right now;
  3. Receive the other command except “Wake up no more information CC” , the Water Sensor will wake up for 8 seconds and then go to sleep.

Channels

The following table summarises the channels available for the DSB45 -:

Channel Channel Id Category Item Type
Binary Sensor sensor_binary Door Switch
Flood Alarm alarm_flood Door Switch
Battery Level battery-level Battery Number

Binary Sensor

Indicates if a sensor has triggered.

The sensor_binary channel supports the Switch item and is in the Door category. This is a read only channel so will only be updated following state changes from the device.

The following state translation is provided for this channel to the Switch item type -:

Value Label
ON Triggered
OFF Untriggered

Flood Alarm

Indicates if the flood alarm is triggered.

The alarm_flood channel supports the Switch item and is in the Door category. This is a read only channel so will only be updated following state changes from the device.

The following state translation is provided for this channel to the Switch item type -:

Value Label
OFF Ok
ON Alarm

Battery Level

Represents the battery level as a percentage (0-100%). Bindings for things supporting battery level in a different format (e.g. 4 levels) should convert to a percentage to provide a consistent battery level reading.

The battery-level channel supports the Number item and is in the Battery category.

Device Configuration

The following table provides a summary of the 5 configuration parameters available in the DSB45. Detailed information on each parameter can be found in the sections below.

Param Name Description
1 Sensor Binary Report Toggle the sensor binary report value
2 Wake up Enable wake up 10 minutes when the power is switched on.
3 Basic set value Toggle the basic set value when the Magnet switch is opened /closed.
121 Reports that will be sent configuration Value 4(LSB)
121 Parameter 121 Value 3 See documentation
  Wakeup Interval Sets the interval at which the device will accept commands from the controller
  Wakeup Node Sets the node ID of the device to receive the wakeup notifications

Parameter 1: Sensor Binary Report

Toggle the sensor binary report value

The following option values may be configured -:

Value Description
0 Open: 00, Close: FF
1 Open: FF, Close: 00

The manufacturer defined default value is 0 (Open: 00, Close: FF).

This parameter has the configuration ID config_1_1 and is of type INTEGER.

Parameter 2: Wake up

Enable wake up 10 minutes when the power is switched on.

The following option values may be configured -:

Value Description
0 Disable
1 Enable

The manufacturer defined default value is 0 (Disable).

This parameter has the configuration ID config_2_1 and is of type INTEGER.

Parameter 3: Basic set value

Toggle the basic set value when the Magnet switch is opened /closed.

The following option values may be configured -:

Value Description
0 Open: 00, Close: FF
1 Open: FF, Close: 00

The manufacturer defined default value is 0 (Open: 00, Close: FF).

This parameter has the configuration ID config_3_1 and is of type INTEGER.

Parameter 121: Reports that will be sent

configuration Value 4(LSB) See documentation for bytes

Setting to 1 send BATTERY

Setting to 16 sends SENSOR BINARY

Setting to 17 sends SENSOR BINARY and BATTERY The following option values may be configured -:

Value Description
0 Do not send anything
1 Send battery report
16 Send Sensor Binary report
17 Send Sensor Binary and Battery reports

The manufacturer defined default value is 0 (Do not send anything).

This parameter has the configuration ID config_121_4_000000FF and is of type INTEGER.

Parameter 121: Parameter 121 Value 3

See documentation set to 1 sends BASIC SET

set to 16 sends ALARM

set to 17 sends ALARM and BASIC SET The following option values may be configured -:

Value Description
0 Do not send anything
1 Send Basic Set
16 Send ALARM
17 Send Basic Set and ALARM

The manufacturer defined default value is 1 (Send Basic Set).

This parameter has the configuration ID config_121_4_0000FF00 and is of type INTEGER.

Wakeup Interval

The wakeup interval sets the period at which the device will listen for messages from the controller. This is required for battery devices that sleep most of the time in order to conserve battery life. The device will wake up at this interval and send a message to the controller to tell it that it can accept messages - after a few seconds, it will go back to sleep if there is no further communications.

This setting is defined in seconds. It is advisable not to set this interval too short or it could impact battery life. A period of 1 hour (3600 seconds) is suitable in most instances.

Note that this setting does not affect the devices ability to send sensor data, or notification events.

This parameter has the configuration ID wakeup_interval and is of type INTEGER.

Wakeup Node

When sleeping devices wake up, they send a notification to a listening device. Normally, this device is the network controller, and normally the controller will set this automatically to its own address. In the event that the network contains multiple controllers, it may be necessary to configure this to a node that is not the main controller. This is an advanced setting and should not be changed without a full understanding of the impact.

This parameter has the configuration ID wakeup_node and is of type INTEGER.

Association Groups

Association groups allow the device to send unsolicited reports to the controller, or other devices in the network. Using association groups can allow you to eliminate polling, providing instant feedback of a device state change without unnecessary network traffic.

The DSB45 supports 1 association group.

Group 1: Group 1

This group supports 5 nodes.
