2 years ago Hey @Hedda,
as we use @koenkk's Z-Stack Firmware without modification, this should available as soon as he implements something is this regard. Also, this is only the "serial device" which connects to ZHA, thus this should bot be applicable?
Please correct me if I'm wrong.
Cheers, Patrik

@codmpm Yes these are only used as a "serial device" by the implementation regardless of which firmware users flash on them.
So this is only a request for OpenThread Border Router (OTBR) RPC firmware compatible with CC2652 radio module that you use.
The purpose with that is to be able to use this CC2652 hardware with the projects agners is developing to use Matter over Thread:
https://github.com/home-assistant/addons-development/tree/master/openthread_border_router
https://github.com/home-assistant/addons-development/tree/master/chip_tool
https://github.com/home-assistant/addons-development/tree/master/chip_controller_repl
https://github.com/zigpy/zigpy/discussions/894
This is not applicable at all for the ZHA integration in Home Assistant as that will only ever be for Zigbee and not Matter.
Koenkk is the developer of Zigbee2MQTT which today is only for Zigbee and as such I do not believe that he have any direct interest in providing OTBR firmware images, (at least not unless he dicide to start developing support for Matter over Thread too, I guess that willl depends if he in the future become personally interested in adding support for the new Matter connectivity protocol over Thread to Zigbee2MQTT or starting a new project for that.).
Thus this is only indirectly related Zigbee2MQTT and ZHA in as far as it is possible to use the same CC26x2/CC13x2 hardware.

1 year ago FYI, missed that tube0013 posted on Twitter that be uploaded a couple of OpenThread RCP firmware images for the CC2652P (TubesZB devices) CC2652R (zzh!) that could be used for initial development and testing as he confirmed those working with agners OTBR addon from addons-development so that could be of interest for those early adopters interested in Thread/Matter support inside Home Assistant:

Again more discussion about CC2652 RPC firmware support for OpenThread here:
https://github.com/home-assistant/addons-development/issues/38
@codmpm Can you please consider providing OpenThread Border Router (OTBR) "RCP mode" firmware images well as "NCP mode" firmware images (with support for the OpenThread
spinel+hdlc+uartprotocol) and preferably using the latest SDK for this Texas Instruments CC2652 based adapter so that it will be compatible with the "OpenThread Border Router Add-on" that Home Assistant developer agners (Nabu Casa employee Stefan Agner) is currently developing? Check out:https://github.com/home-assistant/addons-development/tree/master/openthread_border_router

Thread Spinal RCP mode vs Thread Spinal NCP mode is summarized here:

OTBR should be a "Thread Certified Component" Texas Instruments CC2652 based chips:

The main reason for this request is that an "RPC" firmware with OTBR (OpenThread Border Router) support will make your adapter will be compatible with upcoming Thread based "Matter" (Project CHIP / Connected Home over IP) devices if used in Home Assistant with their other add-ons for the that is also in development. This addon by agners requires that the radio hard a firmware in "RPC" mode instead of the no traditional "NCP" mode:
https://github.com/home-assistant/addons-development/tree/master/chip_controller_repl
https://github.com/home-assistant/addons-development/tree/master/chip_tool
https://github.com/project-chip/connectedhomeip
https://buildwithmatter.com
https://csa-iot.org/all-solutions/matter/
Also having optional OpenThread "NCP" border router firmware would allow users to alternatively use other existing OpenThread applications that use "NCP" mode instead of the newer "RPC" mode which require additional component running on the host. Ex:
https://github.com/openthread/wpantund
Note that so far agners has only worked with Silicon Labs based adapter with OpenThread "RPC" firmware for Thread based Matter (as well as ESP32-C3 based devkit for Matter over WiFi) and that is only because it is a Silabs EFR32MG21 chip based adapter that will ship inside the official Home Assistant Yellow (formerly Home Assistant Amber) hardware:

PS: By the way, you might be interested in the the "Matter" workshop that Home Assistant is holding on the 15th of June even if they are in that specific workshop will not use a Thread based controller or devices and instead use a WiFi (+ Bluetooth) based "Matter" devices:
