Failing to fully pair in zigbee2mqtt about flower HOT 7 CLOSED

I have the same problem.
Sometimes, the device get paired successfully, and for 5 devices, i have all the values, but for others, interview ok, but no value are sent.

I have just tried to pair one to my testing environment on a CC2531 and the devices paired and configured successfully. At least I know there is no problem with the device.

Here are screenshots of some info;

I will continue digging, it might be just poor quality signal, or interference i guess, but that makes me wonder what the reliability of the device is

Had the same issue. In my case some of tricky settings of Zigbee2MQTT gave the result:
Settings - Serial - Adapter - force to zstack
Settings - Serial - Adapter - Disable led.

I'm using cheap CC2531 USB Coordinator. Flashed by CC2531_DEFAULT_20201127 firmware.

I have done some more testing yesterday with my testing environment, usb in laptop, device next to laptop. All 20 devices paired and configured successfully.

So the issue must just be distance, I will try to get them onto my main network and see what i get

Pairing done with the new sonoff dongle, with a cheap cc2530 with the latest firmware and with a diy CC2538... Nothing with the value.
The pairing is ok, but the device doesn't send anything...

Same issue if I try to pair near the coordinator or the router.

So I have finally found the time to play with them further.

The devices paired and configured successfully to my main network and have connected via a router. So not sure what happened there at first. Maybe just a bad connection or interference
