Aqara DS-K02E (Shutter Switch H2 EU): wireless buttons 3/4 stop responding after ~24h, only fixed by physical re-join

[kkbo1]

What happened?

What happened

The two wireless buttons (endpoints 3/4) on an Aqara Shutter Switch H2 EU (DS-K02E) stop responding completely after approximately 24 hours — no action events are published at all. The shutter control itself (endpoints 1/2) keeps working fine.

The only way to restore the buttons is a physical re-join: pressing a button on the switch 2 times short + 1 time long, then allowing join in Zigbee2MQTT (permit_join).

What did you expect to happen

The wireless buttons should keep working indefinitely without requiring periodic manual re-pairing.

Troubleshooting already attempted (none of these fixed it)

Manually triggering device/configure via MQTT after the buttons stopped responding
Setting multi_click_top_wireless_button and multi_click_bottom_wireless_button to false
Restarting the Zigbee2MQTT service
Restarting Home Assistant completely

Interesting data point

Upgrading from Zigbee2MQTT 2.14.1 to 2.14.2 temporarily restored button function for another ~24 hours, after which it failed again in the same way. A plain restart (without a version update) does not have this effect. 2.14.2 included a zigbee-herdsman bump to 10.9.3/10.10.0 — this might point to the root cause being in zigbee-herdsman's network/routing state rather than in Zigbee2MQTT itself, though this is speculation on my part.

Zigbee2MQTT version: 2.14.2
