Zigpy Hello World

This program is an interactive hello world example for the zigpy library.

Supported radios

Have a look under https://github.com/zigpy for the latest supported radios. Here are some of the radios that are supported at the point of writing

https://github.com/zigpy/zigpy-deconz

https://github.com/zigpy/zigpy-xbee

https://github.com/zigpy/zigpy-znp

https://github.com/zigpy/zigpy-cc

https://github.com/zigpy/zigpy-zigate

To change the radio type, replace the zigpy_xbee with your radio type and install the library using pip. Also ensure you change the device settings such as UART baud rate if needed.

from zigpy_xbee.zigbee.application import ControllerApplication

If we were using zigpy-deconz the following would be used:

from zigpy_deconz.zigbee.application import ControllerApplication

Usage

The program is started with ./zigpy_app.py

mg@computer:~/zigpy-standalone$ ./zigpy_app.py 
Started ZigPy ControllerApplication

Example: Pairing and Binding a device

This is an example of how the program can be used to interact with a wall switch.

Pairing the device

First we need to tell the coordinator to go into pairing mode, the ZigBee standard says that the maximum time is 254 seconds, so we provide 120 seconds as the pairing window.

>pair 120
Allowing pairing for 120 seconds

We now put the zigbee device to be paired into pairing mode

When we get a message like this we know the device joined the coordinator.

>device_joined <Device model='TRADFRI on/off switch' manuf='IKEA of Sweden' nwk=0x7E7D ieee=04:cd:15:ff:fe:0f:b2:29 is_initialized=True>

Binding the device

We are using ZigBee ZCL to get data from the switch. This means for the switch to send anything to us we first have to bind to a cluster (See the cluster device info section for how to get a list of the clusters of a device). These clusters are defined by the standard and provide a predefined way of interacting with a device.

>bind 1 1 6 out
IEEE 04:cd:15:ff:fe:0f:b2:29
Binding device <Device model='TRADFRI on/off switch' manuf='IKEA of Sweden' nwk=0x7E7D ieee=04:cd:15:ff:fe:0f:b2:29 is_initialized=True>

Reading material and get started with Zigbee

Clusters

For information about various clusters, have a look in /zigpy/zcl/clusters.

For example in the cluster OnOff (6) the zigpy library defines the attributes and commands in the class

class OnOff(Cluster):
    .....


    attributes: dict[int, ZCLAttributeDef] = {
        0x0000: ZCLAttributeDef("on_off", type=t.Bool, access="rps", mandatory=True),
        0x4000: ZCLAttributeDef("global_scene_control", type=t.Bool, access="r"),
        .....
     
        0xFFFE: foundation.ZCL_REPORTING_STATUS_ATTR,
    }
    server_commands: dict[int, ZCLCommandDef] = {
        0x00: ZCLCommandDef("off", {}, False),
        0x01: ZCLCommandDef("on", {}, False),
        0x02: ZCLCommandDef("toggle", {}, False),
        .....
    }
    client_commands: dict[int, ZCLCommandDef] = {}

Limitations

This program currently does not support sending commands from the coordinator!
