bellows

bellows is a Python 3 project to implement ZigBee support for EmberZNet devices using the EZSP protocol.

The goal is to use this project to add support for the ZigBee Network Coprocessor (NCP) in devices like the Linear/Nortek/GoControl HubZ/QuickStick Combo (HUSBZB-1) device to Home Assistant.

Status

This project is in early stages, so it is likely that APIs will change.

Currently implemented features are:

• EZSP UART Gateway Protocol
• EZSP application protocol
• CLI wrapping basic ZigBee network operations (eg, scanning and forming a network)
• ZDO functionality (with CLI)
• ZCL functionality (with CLI)
• An application framework with device state persistence

An example use of the CLI:

$ export EZSP_DEVICE=/dev/ttyUSB1
$ bellows devices

  NWK: 0x1ee4
