2.7.3 On/Off Cluster ­ MFG Commands

The On/Off cluster can receive the following manufacture specific commands from a client

ZCL header setting ­ Manufacture code for Develco Products is 0x1015
2.7.3.1 Overview
The safe mode functionality is default disabled. To enable the safe mode functionality the Safe mode On or Off command has to be send from the client with payload 1 ­ 255. To disable the safe mode the client has to send a payload with value 0. The safe mode functionality is implemented to assure that the relay enters a predefined state after x minutes.
If “Safe mode On” command is sent to a relay with value 10 minutes, the relay will enter the safe mode after 10 minutes and force the relay to turn ON. If a standard OFF command from the On/Off cluster is sent within the first 10 minutes. The timer is restarted and the relay will not turn ON before the new 10 minute time has timed out. Sending the standard OFF command regularly within the 10 minute time interval will prevent the relay to enter safe mode ON state.
The “Safe mode off” functionality is the same as “Safe mode on” the only different is relay entering off state instead of on state.
After a power failure the remaining time before entering “Safe mode” is set to zero and the device will be forced to enter safe mode immediately.
2.7.3.2 Safe mode Off payload

2.7.3.3 Safe mode On payload

2.8 Occupancy Sensing Client ­ Cluster id 0x0406
It is possible to bind up to 4 occupancy sensors to the SmartPlug. If any of the received states are occupied, the SmartPlug will turn on. If all of the received states are unoccupied, the SmartPlug will turn off. If the SmartPlug does not receive a report from one of the occupancy sensors for 30min, the stored state will time out, and the state will be set based on the remaining active sensor states, if any.

MMI user guide

3.1 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.
3.1.1 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:

• On/Off cluster
• Metering cluster
• Electrical measurement 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.
3.1.2 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.
3.1.3 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.
3.2 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, OccupancySensor 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 behavior

4.1 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 continually scans each ZigBee channel starting from 11 to 24. The LED will flash once every second until it joins a device.
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 “Join / Leave” mode.
4.2 Normal ­ Keep alive
The device is sending a “keep alive” message to the PAN coordinator every 15 minutes to verify that the device is still connected to the network.
4.2.1 Network lost
If no “keep alive” responses are received 5 times in a row (1 hour and 15 minutes), the devices will start scanning every ZigBee channel for the PAN coordinator and try to re-join it. The LED will flash once every second until it rejoins 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.
