Flood sensor - ZWave |
{% include base.html %}
This describes the Z-Wave device Flood sensor, manufactured by Shenzhen Neo Electronics Co., Ltd with the thing type UID of shenzhen_floodsensor_00_000.
The device is in the category of Sensor, defining Device used to measure something.
The Flood sensor 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 Flood sensor 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. Refer to the Wakeup Information section below for further information.
Flood/Water detection
- Remove the sensor cover.
- Make sure the sensor is powered.
- Set Z‐Wave controller or Z‐Wave gateway into inclusion mode (Refer to the controller or gateway operating manual)
- Press the button three times within 1.5 second, the device will enter inclusion mode. And the LED will flash on and off alternately five times..
- Remove the device cover.
- Make sure the sensor is powered.
- Set Z‐Wave controller or Z‐Wave gateway into exclusion mode (Refer to the controller or gateway operating manual)
- Press the button three times within 1.5 second, the device will enter exclusion mode.
The Flood sensor 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.
- You can press the button once to wake up the device and send wakeup notification to controller.
- If press successfully, the LED will blink one time.
- The minimum wakeup interval is 300s
- The maximum wakeup interval is 16,777,200s (about 194 days)
- Allowable interval among each wakeup interval is 60 second, such as 360, 420, 480…
- Note: The default value is 12 hours. This value is longer, the battery life is greater.
The following table summarises the channels available for the Flood sensor -:
| Channel | Channel Id | Category | Item Type |
|---|---|---|---|
| Flood Alarm | alarm_flood | Door | Switch |
| Battery Level | battery-level | Battery | Number |
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 |
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.
The following table provides a summary of the 2 configuration parameters available in the Flood sensor. Detailed information on each parameter can be found in the sections below.
| Param | Name | Description |
|---|---|---|
| 1 | Basic setting command | Basic setting command to be transmitted |
| 2 | OFF delay | The amount of delay before the OFF command is transmitted |
| 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 |
Basic setting command to be transmitted When the water sensor trigger alarm, it will send basic setting with these parameters. The receiver will execute this parameters. For example when the lamp receive the basic setting command, the parameters decide the brightness of the lamp. The following option values may be configured -:
| Value | Description |
|---|---|
| 0 | Off |
| 1 | Dim level (lower bound) (multilevel switch) |
| 99 | Dim level (upper bound) (multilevel switch) |
| 255 | ON (Binary switch) |
The manufacturer defined default value is 99 (Dim level (upper bound) (multilevel switch)).
This parameter has the configuration ID config_1_1 and is of type INTEGER.
The amount of delay before the OFF command is transmitted Adjust the amount of delay before the OFF command is transmitted Values in the range 1 to 65535 may be set.
The manufacturer defined default value is 30.
This parameter has the configuration ID config_2_2 and is of type INTEGER.
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.
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 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 Flood sensor supports 4 association groups.
Sends the BASIC SET control frame when the probe detects water Association group 1 is assigned the status of the device - it sends the BASIC SET control frame to the associated devices when the probe has detected water.
Association group 1 supports 5 nodes.
Association group 2 supports 1 node.
Allows sending notification reports
Association group 3 supports 5 nodes.
Allows sending basic reports
Association group 4 supports 5 nodes.
