Could you point me to where the zigpy-eznp package resides? It is not available on PyPI (https://pypi.org/project/zigpy-eznp/) and I cannot find it on GitHub.

The name of this package is very close to zigpy-znp (in fact, Google autocorrects it). Perhaps zigpy-esp would be a more distinct name?

@chshu I guess this is about the zigpy request in zigpy/zigpy#1052 as well related to your posts in espressif/esp-zigbee-sdk#124 (comment) and -> espressif/esp-zigbee-sdk#124 (comment) about ESP Zigbee NCP host support espressif/esp-zigbee-sdk#124 ?

We are working on a ESP Zigbee NCP solution, which will be based on the ESP Zigbee APIs, and provide the serial interface to communicate with host.

We will also prepare a corresponding zigpy python library to work with Home Assistant. The draft version will be ready in 2024 January.

The ESP Zigbee NCP will not be compatible with ZBOSS NCP. With ZBOSS NCP, users need to run ZCL and part of ZDO on host. We want to integrate ZCL and ZDO in the ESP Zigbee NCP as well, so host can handle the application logic only. If some hosts already have ZCL implementation, it's also flexible to access the NCP network layer directly.

We also have some changes in review so haven't been released. BTW, We hope release it with zigpy on github, Could you help create a project for it?

The PR just want to add it to the zigpy-cli for test.

@lhespress Suggest zigpy-espzb, zigpy-esp-zb, or zigpy-esp_zb is better? Or maybe zigpy-esp-zigbee if it is not too long?

zigpy-espzb, zigpy-esp-zb, or zigpy-esp_zb since ESP_ZB is used in your API, or zigpy-esp-zigbee since in SDK + lib name:

@Hedda@puddly About zigpy-eznp, we means Espressif Zigbee Network Core-Processor Protocol (EZNP), of course, we'll discuss it again, thanks for your suggestion.

@Hedda Right

We can talk about naming later, it isn't important.

BTW, We hope release it with zigpy on github, Could you help create a project for it?

Do you mean under the zigpy organization? I can do that. You can also create the project within the Espressif organization or a personal account and then transfer it.

The PR just want to add it to the zigpy-cli for test.

zigpy-cli requires all of its dependencies be installable. Otherwise, zigpy-cli can't be installed itself. Let me know once you've published the radio library to PyPI and I can test it out or help get it running.
