DWS01 Door and Window Sensor

This describes the Z-Wave device DWS01, manufactured by Hank with the thing type UID of hank_dws01_00_000.

DWS01 product image

The DWS01 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

Unit is labeled with HKZW-DWS01

But, also sold as “MONOPRICE Door and Window Sensor P/N 24259”

Channels

The following table summarises the channels available for the DWS01 -:

Channel Channel Id Category Item Type
Binary Sensor sensor_binary Door Switch
Door sensor sensor_door Door Contact
Tamper alarm alarm_tamper   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

Door sensor

Indicates if the door/window is open or closed.

The sensor_door channel supports the Contact 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 Contact item type -:

Value Label
OPEN Open
CLOSED Closed

Tamper alarm

Indicates if the tamper alarm is triggered.

The alarm_tamper channel supports the Switch item. 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 3 configuration parameters available in the DWS01. Detailed information on each parameter can be found in the sections below.

Param Name Description
14 Enable / disable BASIC SET Enable basic set reporting to group 2
15 Value of BASIC SET Value to send for BASIC SET
32 Level for Low Battery Alarm Adjust the percent of battery left before a low battery level alarm is sent
  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 14: Enable / disable BASIC SET

Enable basic set reporting to group 2

The following option values may be configured -:

Value Description
0 Disable BASIC SET
1 Enable basic set

The manufacturer defined default value is 0 (Disable BASIC SET).

This parameter has the configuration ID config_14_1 and is of type INTEGER.

Parameter 15: Value of BASIC SET

Value to send for BASIC SET

The following option values may be configured -:

Value Description
0 Send 255 when open
1 Send 0 when open

The manufacturer defined default value is 0 (Send 255 when open).

This parameter has the configuration ID config_15_1 and is of type INTEGER.

Parameter 32: Level for Low Battery Alarm

Adjust the percent of battery left before a low battery level alarm is sent

Values in the range 10 to 50 may be set.

The manufacturer defined default value is 20.

This parameter has the configuration ID config_32_1 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 DWS01 supports 2 association groups.

Group 1: Group 1

Association Group 1 This group supports 5 nodes.

Group 2: Group 2

Association Group 2 This group supports 5 nodes.
