Multilevel Sensor#

Shows the ability to advertise numerical sensor readings, such as temperature, and humidity. Multiple parameters can be set for the minimum and maximum values.

The Multilevel Sensor application is based on:



Role Type	Reporting Sleeping End Device (RSS)
Supporting Device Type	Data reporting
Device Type	Notification sensor
Generic Type	Sensor Notification
Specific Type	Notification Sensor
Requested security keys	S2_UNAUTHENTICATED and S2_AUTHENTICATED

Multilevel Sensor transmits the following events:

Environment monitoring
- Temperature, and humidity measure

Supported Command Classes#

Multilevel Sensor implements mandatory and some optional command classes. The table below lists the supported Command Classes, their version, and their required Security class, if any.

Basic Command Class Mapping#

Basic Command Class is not mapped to any of the supported command classes.

Association Groups#

The following table shows the available association groups.


ID	Name	Node Count	Description
1	Lifeline	5	Supports the following command classes: Device Reset Locally: triggered upon reset. Indicator Report: Triggered when LED1 changes state. Configuring parameters: Minimum and maximum temperature levels can be set, errors can be detected if measured temperature is out of range Environmental measurements: Temperature and humidity values can be read, triggered from other Z-Wave devices

Usage of Buttons and LED Status#

To use the sample app, the BRD8029A Button and LEDs Expansion Board must be used. BTN0-BTN3 and LED0-LED3 refer to the buttons and LEDs on the Expansion Board.

The following LEDs and buttons shown in the next table below are used.


Button	Action	Description
RST	Press	Resets the firmware of an application (like losing power). All volatile memory will be cleared.
BTN0	Press	Sends Battery Report, temperature, and humidity data (only if the device is not sleeping)
BTN1	Press	Enter "learn mode" (sending node info frame) to add/remove the device. Removing the device from a network will reset it.
Hold for at least 5 seconds and release	Perform a reset to factory default operation of the device, and a Device Reset Locally Notification Command is sent via Lifeline.


LED	Description
LED1	Blinks with 1 Hz when learn mode is active. Used for Indicator Command Class.

Note : BTN0 only works when the device is already awake, as it is not possible to wake up the device from EM4 via this interrupt due to the silicon.

Firmware Update#

This section will describe backward compatibility when upgrading the MultilevelSensor application from one SDK to a newer version.

SDK 7.1x is the first SDK running on Z-Wave 700.
