ST812 - ZWave |
{% include base.html %}
This describes the Z-Wave device ST812, manufactured by Everspring with the thing type UID of everspring_st812_00_000.
The device is in the category of Sensor, defining Device used to measure something.
The ST812 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 ST812 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.
The flood detector is designed to sense the presence of water in basements, yachts and many others residential and commercial applications, providing early warning of developing floods. The flood detector is designed so that the transceiver is mounted on the wall and its probe is placed in a location where leakage or flooding is probable.
Have Z-Wave Controller enter inclusion mode.
Pressing link key three times within 1.5 second will enter inclusion mode. The detector will stay “awake” for 10 minutes to allow time for setting and device status enquiring.
Have Z-Wave Controller enter exclusion mode.
Pressing link key three times within 1.5 second will enter exclusion mode. The detector will stay “awake” for 10 minutes to allow time for setting and device status enquiring.
The ST812 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.
Pressing link key three times within 1.5 second will wake the device. The detector will stay “awake” for 10 minutes to allow time for setting and device status enquiring.
The following table summarises the channels available for the ST812 -:
| Channel | Channel Id | Category | Item Type |
|---|---|---|---|
| Alarm | alarm_general | Door | Switch |
| Battery Level | battery-level | Battery | Number |
| Alarm (flood) | alarm_flood | Door | Switch |
Indicates if an alarm is triggered.
The alarm_general 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.
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 |
The following table provides a summary of the 1 configuration parameters available in the ST812. Detailed information on each parameter can be found in the sections below.
| Param | Name | Description |
|---|---|---|
| 1 | Basic Level Set | The value sent with Basic commands in case of detected flood |
| 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 |
The value sent with Basic commands in case of detected flood
Values in the range 0 to 99 may be set.
The manufacturer defined default value is 99.
This parameter has the configuration ID config_1_1 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 ST812 supports 2 association groups.
The Detector will send ALARM_REPORT command to the nodes of Group 1 to inform the devices that the Detector is powered up.
ALARM_REPORT Command: [Command Class Alarm, Alarm Type = 0x02, Alarm Level = 0x01]
The second type for Group 1 is SENSOR_ALARM_REPORT. 255 = Alarm, 00 = Event clear.
The third type for Group 1 is ALARM_REPORT type 0x01, Low battery
Association group 1 supports 1 node.
Group to send trigger value to Will send values of 0-99 to devices in Group 2. Set the value to send in Parameter 1.
Association group 2 supports 3 nodes.
