zigpy-cli 1.0.4

Unified command line interface for zigpy radios

zigpy-cli

A unified command line interface for zigpy radios. The goal of this project is to allow low-level network management from an intuitive command line interface and to group useful Zigbee tools into a single binary.

Installation

$ pip install zigpy-cli

Usage

$ zigpy --help
Usage: zigpy [OPTIONS] COMMAND [ARGS]...

Options:
  -v, --verbose
  --help         Show this message and exit.

Commands:
  ota
  radio
  pcap

Make sure ZHA, Zigbee2MQTT, deCONZ, etc. are disabled. Any software controlling your radio requires exclusive access to the hardware: if both are running at once, neither will work.

Network commands

Network commands require the radio type to be specified. See zigpy radio --help for the list of supported types. If your radio requires a different baudrate than the radio library default (mainly EZSP), you must specify it as a command line option. For example, zigpy radio --baudrate 115200 ezsp backup -.

Network backup

$ zigpy radio deconz /dev/ttyUSB0 backup deconz-backup.json

Network restore

$ zigpy radio znp /dev/ttyUSB1 restore deconz-backup.json

Performing an energy scan

$ zigpy radio znp /dev/cu.usbserial-1420 energy-scan

Channel energy (mean of 1 / 5):
------------------------------------------------
 + Lower energy is better
 + Active Zigbee networks on a channel may still cause congestion
 + TX on 26 in North America may be with lower power due to regulations
 + Zigbee channels 15, 20, 25 fall between WiFi channels 1, 6, 11
 + Some Zigbee devices only join networks on channels 15, 20, and 25

Reset a radio

$ zigpy radio --baudrate 115200 ezsp /dev/serial/by-id/some-radio reset

Permit joins

Mainly useful for testing requests.

$ zigpy radio deconz /dev/ttyUSB0 permit -t 60

Changing the network channel

Some devices (like older Aqara sensors) may not migrate.

$ zigpy radio znp /dev/ttyUSB0 change-channel --channel 25

OTA

Display basic information about OTA files

$ zigpy ota info 10047227-1.2-TRADFRI-cv-cct-unified-2.3.050.ota.ota.signed
Header: OTAImageHeader(upgrade_file_id=200208670, header_version=256, header_length=56, field_control=<FieldControl.0: 0>, manufacturer_id=4476, image_type=16902, file_version=587531825, stack_version=2, header_string='GBL GBL_tradfri_cv_cct_unified', image_size=208766, *device_specific_file=False, *hardware_versions_present=False, *key=ImageKey(manufacturer_id=4476, image_type=16902), *security_credential_version_present=False)
Number of subelements: 1

Dump embedded firmware for further analysis

$ zigpy ota dump-firmware 10047227-1.2-TRADFRI-cv-cct-unified-2.3.050.ota.ota.signed - \
      | commander ebl print /dev/stdin \
      | grep 'Ember Version'
Ember Version:    6.3.1.1

Generate OTA index files

Create a JSON index for a given directory of firmwares:

$ zigpy ota generate-index --ota-url-root="https://example.org/fw" path/to/firmwares/**/*.ota
2023-02-14 12:02:03.532 ubuntu zigpy_cli.ota INFO Parsing path/to/firmwares/fw/test.ota

Reconstruct an OTA image from a series of packet captures

Requires the tshark binary to be available.

PCAP

Re-calculate the FCS on a packet capture

Fixes a bug in current EmberZNet SDK releases:

$ # Fix an existing capture
$ zigpy pcap fix-fcs input.pcap fixed.pcap
$ # Fix a capture from stdin and send it to stdout
$ bellows -d /dev/cu.GoControl_zigbee dump -w /dev/stdout | zigpy pcap fix-fcs - - | wireshark -k -S -i -

Database

Attempt to recover a corrupted zigbee.db database:

$ zigpy -v db recover broken.db fixed.db

The final database will have no invalid constraints but data will likely be lost.
