Poll Control – Cluster id 0x0020
The poll control cluster is described in ZigBee Cluster Library Specification This cluster provides a mechanism for the management of an end device’s MAC Data Request rate. For the purposes of this cluster, the term “poll” always refers to the sending of a MAC Data Request from the end device to the end device’s parent. This cluster can be used for instance by a configuration device to make an end device responsive for a certain period of time so that the device can be managed by the controller.
Attribute

Start up, auto scan for client poll control cluster on the coordinator. If it is support on the coordinator an auto bind is created and the humidity sensor will send a check-in command in the interval specified in attribute “CheckinInterval. The coordinator has to reply with a check-in response. The sensor supports the following commands send from the client (Typically the coordinator).

• 0x00 Check-in Response,
• 0x01 Fast Poll Stop,
• 0x02 Set Long Poll Interval,
• 0x03 Set Short Poll Interval,

OTA Upgrade – Cluster id 0x0019
The cluster provides a ZigBee standard way to upgrade devices in the network via OTA messages. The devices support the client side of the cluster. When the devices has joined a network it will automatically auto scan for a OTA upgrade server in the network. If it finds a server an auto bind is created and ones every 24 hour it will automatically send its “current file version” to the OTA upgrade server. It is the server that initiate the firmware upgrade process.

MMI user guide

Push Button Menu
Pushing the button on a device provides the user with several possibilities. Pushing the button for longer (push, hold for a few seconds, and release) allows the user to set the device into a desired mode. A mode change happens at 5 second interval. Below, these modes are illustrated in a state chart .

When cycling through the menu modes, the state is indicated by a number of 100ms blinks on the LED. The device is supporting the ZigBee standardized EZ- mode Commissioning.

EZ mode – Initiator
If the devices is not on the network EZ-Mode Network Steering is invoked when the user enter this menu. The led blinks once every 1 sec until the devices has joined the network. If the device was already on the network it will broadcast the PermitJoin messages. It is the trust center policy that decides if the device is allowed to join the network. When the device has joined the network EZ-Mode Finding and Binding is invoked and the device start to blink every 3 sec until a cluster match is found. When a match is found or the cluster examine is finished the blinking stops and the device sends a messages to the target device to stop the identify time.

The following clusters are support in EZ-mode finding and binding:

• Humidity cluster
• Temperature cluster
• Power configuration cluster

The EZ-mode time is hard coded to 3 minutes. This is the Minimum and recommended PermitJoin time broadcast for EZ-Mode Network Steering and minimum IdentifyTime set for EZ-Mode Finding and Binding. If the user enters the menu again another 3 minutes is started.

EZ mode – Target

• If the devices is not on the network EZ-Mode Network Steering is invoked when the user enter this menu. The led blinks twice every 1 sec until the devices has joined the network. If the device was already on the network it will broadcast the PermitJoin messages. It is the trust center policy that decides if the device is allowed to join the network.
• When the device has joined the network identify mode is invoke and the device start to blink twice every 3 sec until identify mode is stopped or after the EZ-mode time has expired. If the user enters the menu again another 3 minutes is started.

Factory reset

• To allow a device to join a network, one either has to power up a device that has not previously joined a network or push the button until the Reset To Factory default mode is indicated – and subsequently release the button.
• This will cause the device to reset to its factory default state and scan for a suitable coordinator.
• From SW version 3.4.2 the devices will send a network leave indication, if possible, before it starts factory resetting the devices.

Action on Power On

• As a general rule, all end devices and routers that have not previously joined a network (or have been reset to factory default) will start up and search for a network with join permit open. In this mode, the LED will flash once every second.
• Once the device has joined the network, is will start scanning for an OTA server, Time server, Poll control client and an IAS Zone client.
• If a device has joined a network and is powered down, it will attempt to rejoin this network upon power up. For the first 30 seconds hereafter, the device will be available for communication. This time can be expanded using the poll control cluster functionality.

General network behaviour

Installation
When the device is virgin and powered for the first time it will start looking for a ZigBee PAN Coordinator or router to join. The device will scan each ZigBee channel starting from 11 to 24. The LED will flash once every second until it joins a device.

#Scan mode – 1| #Sleep mode| #Scan mode – 2| #Sleep mode| #Scan mode – 2
---|---|---|---|---
Scan all 16 ZigBee

channels until join network or 15

ch x 1 or until join network

| MCU is in sleep mode (Radio off) 15 minutes| Scan all 16 ZigBee

ch x 1 or until join network

minutes|  | ~ 30 seconds|  | ~ 30 seconds

The device will start up using scan mode 1. To increase battery lifetime when the device is joining a network for the first time a scan mode 2 will be used after scan mode 1 has expired. Scan mode 1 it will only be executed one time when the device is powered. If the user invokes EZ-mode it will start scanning the next 3 minutes In section 5 “MMI” it is explained how to put the device into a join or leave network mode. Network settings are stored in NV-memory are after a power cycle the device re-join the same network. If the device has to join a new PAN coordinator the MMI menu supports a “Reset To Factory Fresh Settings” mode. This will erase all current network information.

Normal – Keep alive
The device is sending a “keep alive” message to the PAN coordinator every 15 minute to verify that the device is still connected to the network.
Network lost
If no “keep alive” responses are received 5 times in a row (Worst case 1h15m), the devices will start scanning as specified in the table below. When the device is in scan mode the LED will flash once every second until it re-joins the network. According to the ZigBee specification TX is NOT allowed to be enabled all the time and a TX silent period has to be defined.

#Scan mode – 1| #Sleep mode| #Scan mode – 2| #Sleep mode| #Scan mode – 2

Low battery
The current battery voltage can be read from the power configuration cluster described in section 4.3.1. The attribute “BatteryVoltage” is measuring the battery voltage, in units of 100mV. To detect low battery the system can monitor the “BatteryVoltage“ by setting up a reporting interval of every 12 hour. When a voltage of 2.45V is measured the battery should be replaced. Low batt LED indication – RED LED will blink twice every 60 second
