zigpy-cc is a Python 3 library implemention to add support for Texas Instruments CC series of Zigbee radio module chips hardware to the zigpy project. Including but possibly not limited to Texas Instruments CC253x, CC26x2R, and CC13x2 chips flashed with a custom Z-Stack coordinator firmware.
The goal of this project is to add native support for inexpensive Texas Instruments CC chip based USB sticks in Home Assistant's built-in ZHA (Zigbee Home Automation) integration component (via the zigpy library), allowing Home Assistant with such hardware to nativly support direct control of compatible Zigbee devices such as Philips HUE, GE, Osram Lightify, Xiaomi/Aqara, IKEA Tradfri, Samsung SmartThings, and many more.
zigpy-cc allows Zigpy to interact with Texas Instruments ZNP (Zigbee Network Processor) coordinator firmware via TI Z-Stack Monitor and Test(MT) APIs using an UART/serial interface.
The zigpy-cc library itself is a port of the zigbee-herdsman project (version 0.12.24) by the Zigbee2mqtt project by Koen Kanters (a.k.a. Koenkk GitHub) which in turn was originally forked from the zigbee-shepherd project by zigbeer. Therefore, if any improvements like support for new Zigbee devices that gets added in the Zigbee2MQTT project it could be possible to port those improvements and benifit much of that to the zigpy-cc library.

- ...more coming?
Testing a new release before it is released in Home Assistant.
If you're using Supervised Home Assistant (formerly hassio):
- Add https://developers.home-assistant.io/ as "add-on" repository
- Install "Custom deps deployment" addon
- Update config like:
where 0.2.3 is the new version
pypi: - zigpy-cc==0.2.3 apk: [] - Start the addon
If you're using some custom python installation:
- Activate your python virtual env
- Update package with
pippip install zigpy-cc==0.2.3
The zigpy-cc library is currently being tested by developers with Texas Instruments CC2531 and CC2652R based adapters as as reference hardware but it should in theory be possible to get it working with work most USB-adapters and GPIO-modules based on Texas Instruments CC Zigbee radio module chips hardware. Note that you also have to flash the chip a custom Z-Stack coordinator firmware before you can use the hardware, read the firmware requirement section below.
- CC2531 USB stick hardware flashed with custom Z-Stack coordinator firmware from the Zigbee2mqtt project
- CC2652R dev board hardware flashed with custom Z-Stack coordinator firmware from the Zigbee2mqtt project
- CC2530 + CC2591 USB stick hardware flashed with custom Z-Stack coordinator firmware from the Zigbee2mqtt project
- CC2530 + CC2592 dev board hardware flashed with custom Z-Stack coordinator firmware from the Zigbee2mqtt project
- CC1352P-2 dev board hardware flashed with custom Z-Stack coordinator firmware from the Zigbee2mqtt project
- CC2538 + CC2592 dev board hardware flashed with custom Z-Stack coordinator firmware from the Zigbee2mqtt project
Firmware requirement is that they support Texas Instruments Z-Stack Monitor and Test(MT) APIs using an UART interface (serial communcation protocol), which they should do if they are flashed with custom Z-Stack "coordinator" firmware for Zigbee 1.2 or Zigbee 3.0 from the Zigbee2mqtt project.
The necessary hardware and equipment for flashing firmware and the device preparation process is best described by the Zigbee2mqtt project whos community develops the custom Z-Stack coordinator firmware that this zigpy-cc libary requires.
The Zigbee2mqtt project has intructions for several alternative metods on how to initially flash their special Z-Stack coordinator firmware on a new CC253x, CC26x2R, CC13x2, CC2538 or other Texas Instruments CCxxxx based USB adapters and development boards that does not have a bootloader. They also have a FAQ and knowledgebase that can be useful for working with these supported hardware adapters/equipment as well as with Zigbee devices.

- To configure usb port path for your TI CC serial device, just specify the TTY (serial com) port, example :
/dev/ttyACM0- Alternatively you could try to set just port to

zigpy** is Zigbee protocol stack integration project to implement the Zigbee Home Automation standard as a Python 3 library. Zigbee Home Automation integration with zigpy allows you to connect one of many off-the-shelf Zigbee adapters using one of the available Zigbee radio library modules compatible with zigpy to control Zigbee based devices. There is currently support for controlling Zigbee device types such as binary sensors (e.g., motion and door sensors), sensors (e.g., temperature sensors), lightbulbs, switches, and fans. A working implementation of zigbe exist in Home Assistant (Python based open source home automation software) as part of its ZHA component
ZHA deviation handling in Home Assistant relies on on the third-party ZHA Device Handlers project. Zigbee devices that deviate from or do not fully conform to the standard specifications set by the Zigbee Alliance may require the development of custom ZHA Device Handlers (ZHA custom quirks handler implementation) to for all their functions to work properly with the ZHA component in Home Assistant. These ZHA Device Handlers for Home Assistant can thus be used to parse custom messages to and from non-compliant Zigbee devices. The custom quirks implementations for zigpy implemented as ZHA Device Handlers for Home Assistant are a similar concept to that of Zigbee-Herdsman Converters / Zigbee-Shepherd Converters as used by Zigbee2mqtt as well as that of Hub-connected Device Handlers for the SmartThings Classics platform, meaning they are each virtual representations of a physical device that expose additional functionality that is not provided out-of-the-box by the existing integration between these platforms.
Home Assistant can build ZHA network topology map using the zha-map project.
