Xiaomi/Aqara QBKG26LM doesn't report action state in operation_mode: decoupled

[oliverholliday]

This was resolved by updating firmware of my CC2531 usb zigbee modem

What happened?

I have the following wall switch and I've configured the right hand button to use operation_mode: decoupled. When in this mode no zigbee messages are received in HA for that button.

When in operation_mode: control_relay state changes are visible. I believe this is also the case for other models of the same switch (neutral or no neutral, and the 1/2/3 gang variants).

I have configured state_action: true in the hassio UI for "Settings (specific)".

After pressing buttons a few times the 'State' tab for the device shows:

{
    "flip_indicator_light": "ON",
    "linkquality": 81,
    "operation_mode_center": "control_relay",
    "operation_mode_left": "control_relay",
    "operation_mode_right": "decoupled",
    "state_center": "ON",
    "state_left": "ON",
    "state_right": "OFF",
    "update": {
        "installed_version": 33,
        "latest_version": 33,
        "state": "idle"
    },
    "update_available": false
}

There are other issues referencing this problem but no working solutions:
#12365
#17306

What did you expect to happen?

When in decoupled mode the switch should report an action state change, for the right hand switch the payload should include action: single_right.

How to reproduce it (minimal and precise)

Connect the switch, set operation_mode: decoupled for one of the buttons. Press the button.

To make sure I wasn't reading the logs wrong I created a home assistant automation. The automation triggers if I press any of the buttons except the one that I've configured to be decoupled. The decoupled button does nothing.

I just flashed my CC2531 from 20190608 to 20211115 and it all works correctly.

Sorry about that, I had no idea the firmware was something that could cause this, or that was in active development.

Resolved thanks to Koenkk in #17305 👍

One more thing to add: if you have an Aqara D1 or H1 switch and you're not seeing any power monitoring information I suspect you have the same firmware problem I had.

Up until I updated the firmware of my zigbee modem these properties weren't present in the payload/state.
