From the documentation here I understand that it should be able to go well beyond 1000, but according to this the maximum is 1000. So Unclear what's going on here...

For reference, I'm using a Frient AQSZB-110

Can you share the exposes information of the device?

I would expect that the plugin takes over the range provided by Zigbee2MQTT (so I want to check if one is provided).

[Veldkornet]

Well, the VOC does work and it shows fine in HomeAssistant for example. It's just HomeBridge that complains as soon as it goes above 1000.

{
    "air_quality": "moderate",
    "battery": 100,
    "battery_low": false,
    "humidity": 52.2,
    "last_seen": "2023-03-09T18:54:19+01:00",
    "linkquality": 18,
    "temperature": 16.2,
    "update": {
        "installed_version": 262145,
        "latest_version": 262145,
        "state": "idle"
    },
    "voc": 282,
    "voltage": 3000,
    "update_available": null
}

[itavero]

The check on the limits is something that Homebridge does.
Like I said, I believe I pass the limits provided by Zigbee2MQTT to Homebridge everywhere in my plugin.

If you can share the exposes definition for the device, I can hopefully establish if:

• The limits in the exposes information are wrong.
• There are no limits in the exposes information.
• The limits are correct and the plugin probably isn't passing them on to Homebridge in this specific converter.

If it's one of the first two scenario's, a PR in zigbee-herdsman-converters is probably needed to resolve it.
The last scenario should be resolved in this plugin.

[Veldkornet]

Oh okay, where can I find this information that you need?

[itavero]

As mentioned in the form when you created this issue, the device entry can be found on the MQTT topic zigbee2mqtt/bridge/devices. This includes the exposes information as well.
(note: this is different from zigbee2mqtt/bridge/config/devices)

[Veldkornet]

Currently I don't find this device under zigbee2mqtt/bridge/devices, I'll keep my MQTT client open for a while though to see if it appears....

[satter]

I have Aqara VOCKQJK11LM sensor and I've posted about these warnings here

Here is my device entry from topic zigbee2mqtt/bridge/devices:
voc_aqara.txt

My thoughts on this

1. There should be a conversion from ppb to μg/m3 before reporting voc density to homebridge
   z2m now uses μg/m3 by default but not for all devices (mine will still report ppb).
2. Default limit of 1000 is too low both for ppb and μg/m3 values, I've recorded at least 2000 ppb for my sensor

I will check display_unit setting to compare reported ppb with displayed μg/m3 value

Still having issue

[Jorick-tv]

I found that my Prolight ZIgbee bulbs gave a similar issue:
[homebridge-z2m] This plugin generated a warning from the characteristic 'Color Temperature': characteristic was supplied illegal value: number 555 exceeded maximum of 500. See https.. etc
The colour temperature ended up above what is considered "warmest"
I turned it down in the exposes of the bulbs. Will report back if error persists

[satter]

not stale

[itavero]

@Veldkornet / @addvanced : The issue with the lights is different. As far as I know Zigbee2MQTT includes the range for these properties in the exposes information. If you get a value outside of this range from Zigbee2MQTT, that simply means that the range provided by Zigbee2MQTT is incorrect and should be adjusted in zigbee-herdsman-converters.

With regards to the VOC devices: I would have expected zigbee-herdsman-converters to provide the measuring range of the device as well, but apparently it does not provide this. That means the default range of HomeKit is being used, but I can extend this for sure (if I find time to do so).

I got the same errors with this device.

https://www.zigbee2mqtt.io/devices/VOCKQJK11LM.html#aqara-vockqjk11lm

I starts spamming the log, which kills homebridge-z2m.

It comes alive again when the value is below 1000.

I also got problems with this device:

https://www.zigbee2mqtt.io/devices/E2007.html#ikea-e2007

If you turn off the fan, sometimes the pm25 gets below zero for some reason. This will cause the same error and kill homebridge-z2m
