Gentle Guide to ZigBee

Categories:

Welcome to the gentle guide to ZigBee. This is intended as a starting place for people interested in learning more about ZigBee and how to design, implement, test, manufacture and deploy applications using ZigBee.

After covering foundational knowledge about ZigBee, the document will introduce a residential security system application that will be used to walk through the analysis and decisions that are made in a real ZigBee project during development and production. Finally, an advanced topics section will treat selected topics in further detail for those with a deeper interest.

What kinds of device types are offered by ZigBee's Smart Energy profile?

Categories:

The following describes the different devices in the ZigBee Smart Energy application profile, including their responsibilities, optional features, and some examples:

  • Energy Service Portal (ESP) – This is the gateway device between the Home Area Network (HAN) and the utility’s backhaul network / Neighborhood Area Network (NAN); this device is often a Meter device as well, but it doesn’t have to be. These are usually co-developed with a utility because of the requirement to communicate with the utility’s (usually proprietary) backhaul network infrastructure.

HA on/off switch and light

Categories:

Use case: customization of an HA on/off switch to communicate with an HA light
Chip: EM260
Network: EmberZNet 3.3.1
Tools: ISD 2.0.6, IAR 4.30c

Step 1: Basic ZigBee Introduction

Download the Application Developer’s Guide

Skip to Chapter 4, “Home Automation Application”, which we’ll follow from here. You can refer back to the other pieces of the Application Developer’s Guide if there are concepts that you want to pursue in more depth. You can also refer to the other parts of the gentle guide.

Walkthroughs

Categories:

In this section we feature use case “walkthroughs” that will help you to get started building a particular configuration. A walkthrough should provide all the necessary steps, so if you run into trouble or are unclear about what to do at a certain point, please post a comment to indicate what’s not clear — we’ll update it based on your input.

Under the Hood

Categories:

Under the hood gives a look at the detailed behavior of selected aspects of the ZigBee specification.

Note! It is not necessary to understand these topics to start using ZigBee. These are intended as advanced material for people with particular interest or need to understand it.

Endpoints

Categories:

Each device has a configurable number of endpoints, with a minimum of 2. Endpoint 0 is always the ZDO (see below), and can be used to query the device about its capabilities.

Endpoints 1-240 are available to be used by the application, and they provide unique “addresses” on the same device. In the basic case, only a single endpoint is used.

Device Addressing

Categories:

Device Addresses in ZigBee

Every device in a ZigBee network has two addresses — its globally unique 64-bit address, called the EUI64 or IEEE 64-bit address, and its PAN-unique 16-bit address, or short address.

64 bit addresses

The EUI64 is uniquely allocated by the IEEE to companies which then use them on their networking devices. Ember allocates a single EUI64 address to each chip at manufacturing time — this may be overridden (though not erased) at manufacturing time if desired.

16 bit addresses
