Sonoff ZBMINIL2 not reporting state to HA via Zigbee2MQTT

Configuration Zigbee

I have around 50 devices in my Zigbee2MQTT environment, and all of them work perfectly — except for two Sonoff ZBMINIL2 switches.

The issue: The state of these two switches is not reflected correctly in Home Assistant.
I can control the lights (turn them on and off) from Home Assistant, and I see the correct state updates in the Zigbee2MQTT interface.

Here’s a content of the “status” page from the device in Zigbee2MQTT:

{
    "last_seen": "2025-07-04T14:25:29+02:00",
    "linkquality": 255,
    "power_on_behavior": "previous",
    "state": "OFF",
    "update": {
        "installed_version": 4110,
        "latest_version": 4110,
        "state": "idle"
    }
}

However, in Home Assistant, the entity state remains stuck at "unknown"
Is there anything I can check to figure out why this issue only affects these two devices, while all others work flawlessly?

Thanks a lot in advance!

Did you maybe rename the devices in Z2M and forget to click the “Update Home Assistant entity ID” toggle?

If so, try renaming them again (make sure toggle is on) and check whether the device/entity names in HA match those in Z2M.

Unfortunately this wasn’t the issue with that. I tried renaming it (with the toggle to also change the HA name), the names match and it still doesn’t show the actual status, just ‘unknown’.

Have you compared the firmware version of those two switches to the ones that are working?

Actually, I don’t have any fully working ZBMINIL2. The two that I have and that don’t fully work have different firmware versions (1.0.14 & 1.0.10).
OTA updates aren’t working properly as well, which wouldn’t bother me that much if the state was reported correctly.

I managed to get it working!

It turns out my Zigbee2MQTT configuration.yaml contained a fair amount of unnecessary or broken configuration — most likely some leftover or malformed customization. Here’s what the relevant section looked like:

  '0x60b64.....':
    friendly_name: Light - Eingang - Deckenlampe
    qos: 2
    homeassistant:
      switch:
        type: light
        object_id: light
      light:
        name: light
        value_template: null
      name: null
    state_action: false
    description: Deckenlampe im Eingang
    disabled: false
    optimistic: true
    retain: false

I removed everything except for the friendly_name and qos lines.
I still needed to adjust the type with a helper inside homeassistant, so that the switch became a lightbulb again. But thats an easy fix. I have no clue here all of the configuration came from, but I’m glad that I got it working.
