[Device Support Request] ZBMini-L delayed response after minutes of pairing. Workaround found on Zigbee2MQTT

Context

ZBMini-L is Zigbee 3.0 switch which does not need neutral line for power. It seems to work fine at the beginning but after minutes ZBMini-L switch is paired it shows a delayed response that seems to get worse with time.

To Reproduce Steps to reproduce the behavior:

1. Pair the ZBMini-L with ZHA
2. It responds fast at the beginning
3. Wait 30 minutes or more
4. Switch it ON/OFF and note the delay
5. It gets workse with time

Expected behavior No delay. But it seems to be a workaround for this behavior since it was fixed in Z2M on this commit:

https://github.com/Koenkk/zigbee-herdsman-converters/commit/ac7a095463c8b4dec3d6a6b34eb1e221a0f37d90

Hi First time I tried an OTA from ZHA and finally seems ok.

Previous Firmware: 0x00001004 Now : Firmware: 0x00001101

FYI

I used the following commands

I hope response delay will disappear.

[Daniel-zhan-itead]

We will optimize the firmware to fix the delay issue of ZBMINI-L running on ZHA and release the OTA update image for you. The firmware is under testing, once the test is completed, it will be published.

Is the issue caused by something we are doing?

After ZBMINI-L is added to ZHA, ZHA will enable the device poll control cluster function, and then the device interval of sleep & wake-up will be set to 6 seconds as default, We will disable the poll control function in the device firmware so the interval will be kept at 500ms as default.

Will this also fix the random shutdowns?

Yup, this random shutdown issue will also be fixed together, Pls wait for the new firmware release. Thanks for your understanding
