ZGP project doesn't detect device

[Thoos_96]

Hi everyone,

I recently bought an SR-ZGP2801K4-DIM-S Zigbee Green Power switch (solar-powered), and I would like to connect it to my ESP32-H2 device. I’m trying to use the sample project from the ESP Zigbee SDK:

ESP Zigbee Green Power Sample Project

So far, I have set up my ESP32-H2 and flashed the example, but I’m unsure how to properly pair the SR-ZGP2801K4-DIM-S with it. I’ve tried pressing and holding the switch buttons for 10 seconds, then pressing it once, holding it for 10 seconds again to enter pairing mode, but I don’t see any logs indicating that it’s being detected.

I believe i flashed the code right because i have the following logs on my terminal :

I (450) gpio: GPIO[9]| InputEn: 1| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:4
I (450) ESP_ZGP_COMBO: Deferred driver initialization successful
I (460) ESP_ZGP_COMBO: Device started up in non factory-reset mode
I (470) ESP_ZGP_COMBO: Device rebooted
I (1070) ESP_ZGP_COMBO: Network(0x4cd9) is open for 180 seconds


Does anyone have experience with pairing Zigbee Green Power devices with ESP32-H2? Any guidance on troubleshooting or specific configurations required in the sample project would be greatly appreciated!

Thanks in advance!

HI Thoos_96, hi Everyone,
What example did you set?
I’m trying to do the same thing you did with a ESP32-C6 and a Schneider ZBRT2 switch.

At the moment the only positive result is obtained with a NTX dongle OM15020 JN5169, I can see all Zigbee GP traffic
Who can help us with the green power use of ESP32 H2 and C6 cards?
Regards
Fred

Hi everyone,
OK you tried with the program esp-zigbee-gpc, but this example is not really a sniffer, it expects a Zigbee LAN or something equivalent.
It is not able to understand a Zigbee Green Power frame emitted with a switch in harversting energy technology.
Who can recommend the right example to capture this type of signal?
Cordially

Hi everyone.
Well, the ESP32-C6 circuit is absolutely not supported by its manufacturer in the Zigbee Green Power aspects, especially with switch in harversting energy technology.
While waiting to have available an example and a development tool at the level of Espressif, I recommend to use for this the dongle NTX OM15080.
