Xiaomi buttons no longer working

#Bug Report

What happened

Xiaomi wireless buttons devices no longer work. Nog logging appears with log_level: debug and "zigbee_shepherd_debug": "true". Status in HA is "unknown"

What did you expect to happen

See some actions from the buttons when pressed.

How to reproduce it (minimal and precise)

Previously I wat running zigbee2mqtt nightly. When I switched to 1.19.0, the buttons just don't work anymore. Other Xiaomi devices (curtain controllers for example) do work.

Debug Info

zigbee2mqtt version: 1.19.0
CC253X firmware version: CC2531_DEFAULT_20190608

[BarBaar44]

Tried so far:

• reinstalled version 1.19.0
• Moved back to edge version
• used a different CC2531

All no result ...

This indicates that the button does not send any messages at all anymore.

Did you try to repair the buttons or replace the batteries?

[BarBaar44]

No, but the issue is: I have the exact same problem will all 4 of my buttons (2 different types).

Have not yet tried to re-pair the buttons, but I am afraid this will be the only option left.

[BarBaar44]

Ended up re-paring all buttons. Weird they just stopped working...

Reopening this one, as I lost both Xiaomi WXKG01LM buttons again today. They just no longer work..

WXKG02LM buttons are still working.

i have the same. Every day they stop working, no response anymore in zigbee2mqtt
Just updated to latest dev, hopefully this will fix it

When this happens, could you provide the sniff log when pressing the button? (https://www.zigbee2mqtt.io/how_tos/how_to_sniff_zigbee_traffic.html) This should give us an idea were the issue is coming from.

Closing this as, as this seems to be solved since I started using a CC2530 + CC2591 router
