tinkerhub-bridge-zigbee v0.1.0

Zigbee Device Bridge for Tinkerhub

This module provides support for bridging devices found in a Zigbee network and to bring them into a Tinkerhub as devices. It provides generic access to all devices allowing them to be enhanced with specific functionality by running other modules anywhere in the network.

Running only this module is usually not what you want, combine with specific device implementations such as tinkerhub-device-zigbee-light to expose the devices in a more user friendly way.

This module uses zigbee-shepherd for connecting and managing the Zigbee network. Any hardware supported by zigbee-shepherd will work with tinkerhub-bridge-zigbee. These currently are:

• SmartRF05EB (with CC2530EM)
• CC2531 USB Stick
• CC2538
• CC2630/CC2650

CC2530/31 needs specific firmware, see the Hardware Wiki-page for how to install this on your hardware.

Installation and setup

To install in your local project:

npm install --save tinkerhub-bridge-zigbee

If you are not using th.autoload() include module with require('tinkerhub-bridge-zigbee').

When running your local project a new device of type bridge-zigbee will be made available. To create a Zigbee network you need to tell this bridge which USB-port to use. The easiest way to do this is via the CLI:

$ tinkerhub
> type:bridge-zigbee connect /dev/ttyACM0
 SUCCESS zigbee:bridge:ix77x0i92jyi
  configured: true
  connected: true

Make sure that Node has read and write permissions to your USB-device.

Adding Zigbee devices

Call permitJoin on the brdige to allow Zigbee devices for 60 seconds.

$ tinkerhub
> type:bridge-zigbee permitJoin
 SUCCESS zigbee:bridge:ix77x0i92jyi
  null

After this put your device into the correct mode, usually by turning it on or pushing a link button. If it pairs correctly a new device of type zigbee will show up.

Extending devices

As this module only exposes that basic Zigbee device you need to extend devices with more useful functionality. You probably want to keep the Zigbee Cluster Library documentation handy when working on your extended device.

const th = require('tinkerhub');

th.devices.extend([ 'type:zigbee' ], function(encounter) {
	encounter.device.zigbeeInspect()
		.then(function(deviceData) {
			// Check for endpoints and clusters required here

			// If you have everything you need you can extend the device
			const extendedDevice = {
				metadata: {
					type: 'super-fancy-device'
				}
			};
			encounter.enhance(extendedDevice);
		});
})

Device actions and events

Action: zigbeeInspect

Return details about the Zigbee device. This will return information about all endpoints and clusters available.

Action: zigbeeFoundation(endpoint, clusterId, command, data)

Perform a foundation command on the specified endpoint. This can be used for things such as reading multiple attributes. See zcl-packet for names of commands.

device.zigbeeFoundation(endpoint, 'genBasic', 'read', [
	{ attrId: 3 },
	{ attrId: 4 }
]).then(function(data) {

});

Action: zigbeeRead(endpoint, clusterId, attribute)

Perform a read of a single attribute.

device.zigbeeRead(endpoint, 'genBasic', 'manufacturerName')
	.then(function(name) {

	});

Action: zigbeeFunctional(endpoint, clusterId, command, data)

Perform a functional command on the Zigbee device. This is used for things such as turning a device on or off. See zcl-packet for names of commands.

device.zigbeeFunctional(endpoint, 'genOnOff', 'toggle', {})
	.then(function() {

	});

Event: zigbee:value

Event emitted when a value is reported to have changed. Data is an object with the following keys:

• endpoint
• cluster
• attribute
• newValue
