CC2530: ZNP how to receive all messages from other devices in network

Hi Cuong,

We can see if Koen Kanters will comment on the zigbee2mqtt ZNP firmware changes, but it may involve adding MT_*_CB_FUNC to the znp.cfg file.  You might be interested in MT_MAC_CB_FUNC and MT_NWK_CB_FUNC as these are missing from the default configuration. You can review Section 1.2 of the Monitor and Test API for details.   Are you using different ZNP firmware for the zigbee2mqtt ZC and Z-Tool ZR, and what messages are missing?

Regards,
Ryan

Hi Ryan,

I use both ZNP CC2530 firmware for ZC, and ZR, from https://github.com/Koenkk/Z-Stack-firmware

On ZC via Zigbee2MQTT, I can interact to the end device bidirectionally. On ZR, via Z-Tool, I can't get/transmit to to the end device. I can use ZDO_NWK_ADDR_REQ to get the end device address.

I dont know what functions Zigbee2MQTT software uses to interact with the end device. 

If the TuYa door sensor sends all messages directly to the coordinator then you won't be able to receive them on the router.

Thank Koen for your info. Is there any ways such as group or binding for ZR receiving its data?

Many users uses Zigbee2MQTT to control/access their devices. I want to make a controller as ZR to hook into zigbee network, so that I can control/access those zigbee devices without affecting their settings.

Also I try to discover its endpoint with ZDO_ACTIVE_EP_REQ, so that I can read its data. But operation failed.

On Zigbee2MQTT, which command do you use to get its data when users access API MQTT zigbee2mqtt/friendly_name/get?

Are all Tuya Zigbee devices using private profile?

Thank you.

I don't think TuYa devices can be bound to different addresses, note that these don't follow the spec very well so many standard zigbee commands fail.

Thank Koen,

I'm reading documents about Tuya on zigbee2mqtt to understand Tuya Zigbee devices. Previously, I think zigbee devices would follow Zigbee standards well.

Since you are using the same firmware on both the ZC and ZR, I agree with Koen's assessment.  ZEDs will only directly communicate with its parent, and furthermore Tuya's BDB may be configured such that it does not allow grouping or binding to multiple devices.  You can search other online forums or contact Tuya for more information regarding their products.
