Port cc-znp to communicate with TI CC253X / CC26X2R1 Zigbee Network Processor (ZNP) with Z-Stack firmware over UART serial port #85

Gamester17 · 2018-09-25T13:03:04Z

Would it be possible to port the cc-znp library (or the newer forks of it) from JavaScript to Python to use as a base in a radio module for Zigpy to communicate with cheap TI CC253X based USB dongles when they are flashed with the custom Z-Stack firmware that the Zigbee2mqtt project has developed?

Texas Instruments CC253X based dongles like the inexpensive CC2531 USB sniffer sticks you can buy from China for less than $9 including shipping are readily available hardware and recently been made very popular by the Zigbee2mqtt (Zigbee to MQTT bridge) project which made a custom Z-Stack firmware for have them which has full Zigbee 3.0 stack with coordinator functionality (the project provide both Z-Stack 1.2 and Z-Stack 3.0 coordinator firmware, and also repeater firmware as well).

cc-znp library which was written in JavaScript is an integration interface for a host to communicate with the Z-Stack firmware running on TI CC253X Zigbee Network Processor (ZNP) using a serial protocol over a serial port via TI Z-Stack Monitor and Test (MT) APIs upon a UART interface. This cc-znp libary was utilized by the original zigbee-shepherd project and now also in the newer zigbee-herdsman project as well as some other projects which makes use of the use of custom Z-Stack firmware on CC253X chips. Most of which are based on Texas Instruments Z-Stack SDK (like the custom Z-Stack firmware available from the Zigbee2mqtt project).

https://github.com/zigbeer/cc-znp/wiki

Note! Best would probably be to port the code from newer forks of the cc-znp library which contains updated code and are better maintained:

https://github.com/Koenkk/cc-znp
https://github.com/open-zigbee/zigbee-bridge-znp
https://github.com/Koenkk/zigbee-herdsman

Update!: FYI @sanyatuning started development on a cc-znp python port as a module for Zigpy here:

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

Another update! FYI, Adminiuga & puddly started development zigpy-znp as a alternative module here:

https://github.com/zha-ng/zigpy-znp
and here:
https://github.com/puddly/zigpy-znp

FYI; ioBroker is another JavaScript based project which Zigbee via same custom Z-Stack by Koenkk (ioBroker Zigbee module is based on zigbee-herdsman library and their new converters database)

https://github.com/ioBroker/ioBroker.zigbee

ioBroker claim to not only support CC2531/CC2530 but also CC26x2R and CC2538 (+ CC2592 PA)

https://github.com/ioBroker/ioBroker.zigbee/blob/master/README.md

Update! Z-Stack firmware from @Koenkk now also has experimental support CC2652R / CC26X2R1 based USB sticks and he has added Zigbee 3.0 support in Z-Stack 3.0 firmware as well. CC2652R by Texas Instruments is a new high-performance Zigbee chip which is much faster and contains much more memory than the CC2530 and CC2531 chips, (bonus is that Texas Instruments LAUNCHXL-CC26X2R1 LaunchPad development kit board requires no additional flashing hardware is needed, as the board has an on-board programmer).

https://github.com/Koenkk/Z-Stack-firmware
https://github.com/Koenkk/zigbee2mqtt
https://www.zigbee2mqtt.io

Do you think that Zigpy support CC253x (like CC2531) chips with custom Z-Stack firmware could be achieved by porting cc-znp from the latest zigbee-shepherd and zigbee-herdsman by Zigbee2mqtt project?

As I understand it, that custom Z-Stack firmware could possibly also be made compatible with additional Zigbee USB sticks/boards, like those based on CC2530, CC2530EM, CC2538, CC2540, CC2630, CC2650, CC2590, CC2591, and CC2592 chips from Texas Instruments as well?

https://github.com/zigbeer/zigbee-shepherd/wiki
https://github.com/zigbeer/documents/tree/master/zigbee-shepherd

Anyway, cc-znp, zigbee-shepherd, and zigbee-herdsman are all open-source software written in JavaScript. They support TI's CC253X wireless SoC as a zigbee network processor (ZNP) with custom Z-Stack firmware, and takes the ZNP approach with cc-znp to run the CC253X as a coordinator and to run zigbee-shepherd or zigbee-herdsman as the host.

@Koenkk who is the developer of zigbee2mqtt has most recently been developing zigbee-herdsman as a fork of zigbee-shepherd and is an improved replacement for zigbee-shepherd

https://github.com/Koenkk/zigbee-herdsman-converters

PS: Zigbee2mqtt also have source code as well as pre-built firmware for a custom Z-Stack firmware :

Please also see the updated znp forks that is used by then open-zigbee and zigbee2mqtt projects today:

leobel96 · 2019-01-24T15:27:21Z

+1 for TI CC253X support

highground88 · 2019-01-25T13:57:54Z

Also keen on testing with the Texas Instruments CC2531 in particular. Cheap device and very flexible.

andriej · 2019-03-20T07:43:03Z

+1, would be superb

Has anyone made any progress with Zigpy for CC253x USB sticks with custom Z-Stack firmware?

https://github.com/Koenkk/Z-Stack-firmware

Gamester17 · 2019-12-12T10:56:36Z

FYI, it looks like the Z-Stack firmware from @Koenkk now also has experimental support CC2652R / CC26X2R1 based USB sticks and he has added Zigbee 3.0 support in Z-Stack 3.0 firmware as well

https://github.com/Koenkk/Z-Stack-firmware

CC2652R by Texas Instruments is a new high-performance Zigbee chip which is much faster and contains much more memory than the CC2530 and CC2531 chips

Koenkk posted some more information about CC2652R here Koenkk/zigbee2mqtt#1429

**_Notes

The device can be bought here: http://www.ti.com/tool/launchxl-cc26x2r1
No additional flashing hardware is needed, it has an on-board programmer (no CC debugger needed).
The board has +- the size of a Raspberry Pi
Zigbee 3.0!
Flash using Flash Programmer v2
Firmware can be found here in the bin folder: https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator/Z-Stack_3.x.0
It's not possible to migrate your Zigbee 1.2 network (requires repairing)
The network restore trick that we used in Zigbee 1.2 doesn't work anymore (due to better security policies). A backup of the CC2652R is taken at every shutdown of zigbee2mqtt, file can be found under data/coordinator_backup.json. This backup is automatically restored when starting with a new flashed CC2652R._**

Gamester17 · 2019-12-19T13:57:24Z

FYI, Tasmota is another popular project that makes use of the Z-Stack-firmware from Koenkk

https://github.com/arendst/Tasmota/wiki/Zigbee

Z2T (Zigbee to Tasmota) concept allows you to make your own Zigbee to WiFi bridge by combining Z-Stack-firmware on CC2530 and Tasmota firmware on ESP8266 / ESP82xx hardware.

sanyatuning · 2019-12-25T09:02:14Z

FYI
I started working on this :)

Hedda · 2020-01-03T13:22:32Z

@sanyatuning Awesome that you started on this! I for one will now be ordering a CC2531 USB sniffer and keep an eye on your repository at https://github.com/sanyatuning/zigpy-cc

Gamester17 · 2020-01-07T07:48:04Z

@sanyatuning Very cool! Which version of Z-Stack firmware are you testing? It's from Koenkk or?

https://github.com/Koenkk/Z-Stack-firmware

Z-Stack 3 (3.x) supports the full Zigbee 3.0 specification according to these discussions here:

Koenkk/zigbee2mqtt#1429
Koenkk/zigbee2mqtt#1568

FYI, this Z-Stack 3.0 and later firmware has experimental support in Zigbee2mqtt dev branch.

Gamester17 · 2020-01-13T11:27:40Z

FYI; ioBroker is another JavaScript based project which Zigbee via same custom Z-Stack by Koenkk

sanyatuning · 2020-01-16T07:10:47Z

@Gamester17 my port is based on zigbee herdsman. I'm testing with z-stack 1, but it can be compatible with v3.
I would like to continue developing it this week.

dzungpv · 2020-01-17T06:26:30Z

@sanyatuning Great effort! I use zigbee2mqtt for year, but native component for HA always the best.

Gamester17 · 2020-02-02T09:15:39Z

@sanyatuning see that @puddly now submitted a pull request for CC26X2R1 support to your zigpy-cc

zigpy/zigpy-cc#8

FYI, in related news I also that "zig-a-zig-ah" ("zzh" for short) USB-stick form-factor dev board based on CC2652R / CC2652P has been announced as an open-source hardware design by Electrolama ( @omerk and friends ) under open source Solderpad Hardware Licence Version 2.0

https://github.com/electrolama/zig-a-zig-ah/

Gamester17 · 2020-02-13T14:10:52Z

FYI, looks like @sanyatuning has now submitted initial (“Beta”) support for Home Assistant integration:

home-assistant/core#31621

home-assistant/home-assistant.io#12051

Hedda · 2020-03-25T11:21:23Z

FYI, it looks like Adminiuga (and puddly via a fork) started on zigpy-znp as an alternative to zigpy-cc

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

It has not been updated by Adminiuga in about 4-months but puddly continues in his fork here:

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

Neither of those projects has yet been announced so are still both very early work in progress.

puddly · 2020-03-25T22:28:04Z

I'm pretty close to getting zigpy-znp running. I'm just waiting for a second TI radio so that my entire house is not unusable while I fix bugs.

Adminiuga · 2020-05-10T21:35:25Z

There's https://github.com/zigpy/zigpy-cc and work being done in https://github.com/zha-ng/zigpy-znp

Can continue discussions in those repos.
