NQ-9021 - ZWave |
{% include base.html %}
This describes the Z-Wave device NQ-9021, manufactured by NorthQ with the thing type UID of northq_nq9021_00_000.
The device is in the category of Sensor, defining Device used to measure something.
The NQ-9021 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 NQ-9021 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 Z-Wave Smart Meter Sensor is a compact sensor designed to read meter values from traditional electromechanical and electronic meters with optical port. The sensor is easy to install and ideal for precise meter reading down to 0,1kwh. Its compact size and external wireless transmitter makes it easy to install in any distribution board. The device is battery powered (will last about 1 year) and reports the meter value once in 15 minutes. If there won't be a Z-Wave network, the device will store values up to 3 month. This ensures, that the system can even be used in a minimal configuration with a simple Z-Wave USB Stick (Not part of delivery!) connected to a PC.

Press the sensor button 3 times
The NQ-9021 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.
A single click on the Z-Wave button will wake up the device
The following table summarises the channels available for the NQ-9021 -:
| Channel Name | Channel ID | Channel Type | Category | Item Type |
|---|---|---|---|---|
| Electric meter (kWh) | meter_kwh | meter_kwh | Energy | Number |
| Battery Level | battery-level | system.battery_level | Battery | Number |
| Clock Time Offset | time_offset | time_offset | Time | Number |
Indicates the energy consumption (kWh).
The meter_kwh channel is of type meter_kwh and supports the Number item and is in the Energy category. This is a read only channel so will only be updated following state changes from the device.
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%.
Provides the current time difference for the devices time.
The time_offset channel is of type time_offset and supports the Number item and is in the Time category.

This parameter has the configuration ID config_15_4 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 device does not support associations.
