SM-A702A Window/Door Sensor
This describes the Z-Wave device SM-A702A, manufactured by Sigma Designs (Former Zensys) with the thing type UID of sigma_sma702a_00_000.
The device is in the category of Sensor, defining Device used to measure something.
The SM-A702A 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 SM-A702A 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.
Overview
Door/Window sensor with LED indicator, battery powered.
Inclusion Information
Press Z-Wave button once to wake up the device then once to connect to Z-Wave network
Exclusion Information
Press Z-Wave button once to wake up the device then once to disconect from Z-Wave network
Wakeup Information
The SM-A702A 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.
Press Z-Wave button once to wake up the device
Channels
The following table summarises the channels available for the SM-A702A -:
| Channel Name | Channel ID | Channel Type | Category | Item Type |
|---|---|---|---|---|
| Binary Sensor | sensor_binary | sensor_binary | Switch | |
| Alarm (general) | alarm_general | alarm_general | Alarm | Switch |
| Battery Level | battery-level | system.battery_level | Battery | Number |
Binary Sensor
Indicates if a sensor has triggered.
The sensor_binary channel is of type sensor_binary and 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 |
|---|---|
| ON | Triggered |
| OFF | Untriggered |
Alarm (general)
Indicates if an alarm is triggered.
The alarm_general channel is of type alarm_general and supports the Switch item and is in the Alarm 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 system.battery-level channel is of type system.battery-level and supports the Number item and is in the Battery category.
This channel provides the battery level as a percentage and also reflects the low battery warning state. If the battery state is in low battery warning state, this will read 0%.
Device Configuration
The device has no configuration parameters defined.
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 device does not support associations.
