I looked through the debug messages, to me it looks like:
The "dp":2
messages should be formaldehyde.
The "dp":18
- temperature, which they already are.
The "dp":19
- humidity, permille, but always a multiple of 10. Seem to be handled correctly.
The "dp":21
- seem to be voc, and already handled correctly.
The "dp":22
- match up with CO2 on the Wifi device, currently affects "formaldehyd" in the output.
i've also got a problem with this device. My coordinator is breaking due to too spamming
adapter cc2531
I'm use zigbee2mqtt version 1.22.0-2, coordinator zStack3x0 firmware 20211217 TS0601 _TZE200_ryfmq5rl Air quality sensor not only are the output parameters of carbon dioxide and formaldehyde sensors mixed up, but this device sends so many data reports every second that my server can’t cope with their processing and freezes, doesn’t display (can’t load) the history of indicators, because of this, they work every other time automation based on this device's data, spamming logs unnecessarily filling disk space and constantly writing and rewriting data to the disk has already disabled two microSD cards and one solid state drive. I have previously written about this issue.
Zigbee2MQTT version 1.24.0-dev commit: a73a5b2 Coordinator type zStack3x0 Coordinator revision 20211217
I can confirm this issue as well.
device is reporting values few times per second

I have four of the "TS0601_smart_air_house_keeper" devices (_TZE200_dwcarsat) and every one seems to also swap the co2 and the formaldehyd sensor readings. I suspect this is a bug in the device, and not zigbee2mqtt as every other zigbee consumer seems to have this issue. Using another sensor nearby that reports correctly, the numbers generally line up, and the pm25 reading seems consistent, as does voc, temp. and humidity.
I'd be interested to see an option to swap these in zigbee2mqtt as a device flag perhaps.
And reject bogus values, as I don't think anything that measures ppm should ever see 43,000...
Swapping should already have been fixed in z2m 1.25.0 (https://github.com/Koenkk/zigbee-herdsman-converters/pull/3982)
Seems it is not (maybe not for all devices ?)

This is embarrassing! The prospect of reconfiguring half of the server configuration, additional installation of core library components, flashing the stick (which, as the list of bug reports shows, also does not work quite correctly). And how the system will behave with these innovations is not yet clear! At the moment, I don’t have the opportunity (mainly related to redundancy) to somehow contribute to the development and test new versions of the software, no matter how trite it sounds, I renamed their names in the display form solves the problem itself with the correctness of sending and the frequency of updating values, but purely visually acceptable and correct.

@debnetjm also fixed it for the _TZE200_ryfmq5rl
now.
Changes will be available in the dev branch in a few hours from now. (https://www.zigbee2mqtt.io/advanced/more/switch-to-dev-branch.html)
@frfstu
I don't get what you are saying here. It's just the zigbee2mqtt that needs updated here, not the firmware on the zigbee devices.
Jokers .. I read all this yesterday (crossed out today) as I imagined that I would have to re-configure almost everything (including some automations), I was just indescribably delighted!

@Koenkk something's changed, co2 seems to be OK I am not sure about formaldehyd
formaldehyd seems to be too high and too similar to co2 reading (see graph)
using latest-dev

Hi @debnetjm
I just fall on this thread but maybe you should remove the device completely and add it again because I just connected mine yesterday, and I got value close to 0 until 10 for the formaldehyd attribute so I don't understand yours :)
Edit: my bad, forget what I said ... I just saw that was not the [TS0601_air_quality_sensor] ... I didn't read the inital thread correctly sorry. But in your logs we can see "model": "TS0601_air_quality_sensor" , this mislead me :)
@Koenkk Correct me if I am wrong but seems we have the same device [TS0601_air_quality_sensor] from different vendors
so we should see the same values reported
they seem to be different for me
no pm25 no unit for formaldehyd
I am wondering if values are correct
I see you have voc 13 but I have 0-1.0 never more than 1
co2 seems weird for me as well
my range is 358-368, is it possible that we have such similar values (you have 358) and my min/max si with 8 at the end in such short range ? coincidence ? I do not think so :)
@debnetjm could be that yours uses different data point ids, to figure them out follow https://www.zigbee2mqtt.io/advanced/support-new-devices/03_find_tuya_data_points.html#requirements-and-caveats
@Koenkk they seems to be OK but DPs are not fixed for Smart Air Box in tuya.js

@debnetjm are correct values reported when paired through the TuYa app and can you provide the data/database.db entry of your device?

Changes will be available in the dev branch in a few hours from now. (https://www.zigbee2mqtt.io/advanced/more/switch-to-dev-branch.html)
Just got my TS0601 air quality thing with pm25 today, came here for this bug. I guess it's fixed now but not in the released branch?
In latest master: {"co2":397,"formaldehyd":396,"humidity":41.8,"linkquality":153,"pm25":6,"temperature":25.4,"voc":52}
Previously co2 was 5-7... I'll see if I can get around to test the dev branch
@Koenkk indeed seems to be much better
two things: 1) formaldehyd - missing unit name (mg/m³) voc - I think should be ppm not ppb
2) scale for formaldehyd and voc, I think itshould be 0.01-0.02 (formaldehyd) and 0.0-0.1 for voc as per screenshot from tuya application and definition from tuya platform ?
ch2o_value | Integer | { "unit": "mg/m³", "min": 0, "max": 1000, "scale": 2, "step": 1 } voc_value | Integer | { "unit": "ppm", "min": 0, "max": 999, "scale": 1, "step": 1 }

I'm seeing a lot of trash pm25 values, should those be filtered on zigbee2mqtt level or later?

43691 is 0xaaab, basically the bitfield "1010101010...". Seeing 43692 too (0xaaac). Normal pm25 for the sensor is around 5.
@debnetjm
1) formaldehyd - missing unit name (mg/m³) voc - I think should be ppm not ppb
fixed
scale for formaldehyd and voc, I think itshould be 0.01-0.02 (formaldehyd) and 0.0-0.1 for voc as per screenshot from tuya application and definition from tuya platform ?
What do you mean with scale?
@Mirarkitty
43691 is 0xaaab, basically the bitfield "1010101010...". Seeing 43692 too (0xaaac). Normal pm25 for the sensor is around 5.
Are any good values published at all? If yes we can filter the 43692 values.
@Koenkk
I mean reported values should be scaled properly, as described on tuya platform.
ch2o_value | Integer | { "unit": "mg/m³", "min": 0, "max": 1000, "scale": 2, "step": 1 } voc_value | Integer | { "unit": "ppm", "min": 0, "max": 999, "scale": 1, "step": 1 }
as I understand above means device is reporting ch2o values in range 0-1000 but the real value should be scaled with precision 2. That means the real value is between 0,00 - 10,00 (scale 2)
the same for voc
reported values 0 - 999 what means real value is between 0,0 - 99,9 (scale 1)
@debnetjm so basically ch20 should be divided by 100 and voc by 10?
@Koenkk correct
Are any good values published at all? If yes we can filter the 43692 values.
Yes, about 95% or more are correct.
I also recently bought this device (or at least similar one) but it seems my issue is different. For me I get this when the device is connected:
Warning zigbee-herdsman-converters:TuyaSmartAirBox: Unrecognized DP #20 with data {"dp":20,"datatype":2,"data":{"type":"Buffer","data":[0,0,0,43]}}

It shows up as TS0601 _TZE200_dwcarsat ([TS0601_smart_air_house_keeper)
These are the readings i currently get from it.

}
I am currently on Zigbee2mqtt version 1.25.0-1.
it seems I am missing the formaldehyd value entirely. Also the pm25 value seems way too low it should be (sadly) much higher in my area this time of year. The pm25 should be above 100
@debnetjm fixed now
@Mirarkitty 0xaaab
pm25
will be ignored now.
@Aaike can you try with the latest dev first?
Changes will be available in the dev branch in a few hours from now. (https://www.zigbee2mqtt.io/advanced/more/switch-to-dev-branch.html)
for me it works well but it is impossible to write the data in the DB because the sensor sends data nearly every 0.1 sec. This causes the DB to grow for hundred MB each day. Is there a way to avoid that ?

Hi,
The erroneous pm25 value is 43692, which is 0xaaac (and not 0xaaab).
I have 4 of Tuya Air Quality monitor sensors and I switched to using the Edge version of the Z2m yesterday night. But I can still see the high pm25 coming.
Could you please check and fix this?
Regards

The erroneous pm25 value is 43692, which is 0xaaac (and not 0xaaab).
It's both, as what I wrote above:
43691 is 0xaaab, basically the bitfield "1010101010...". Seeing 43692 too (0xaaac).
Possibly other values too, I get random spikes, but I haven't investigated more. My pm25 sensor seems to only give noise near zero otherwise, I can't get it to read any dust.
I opened it and the pm25 sensor is jammed shut towards the bottom and top of the box (???), could be the reason. Will have to print a new case or run it open, I guess. Also co2, formaldehyde and voc are weirdly linked. None of this is the fault of zigbee2mqtt, though, I'm sure.

Sorry 🙏 my fault.. I agree, it is both these value.
Also please let share if running it open makes any difference or not.
Thanks
Ignored both values now (0xaaac
and 0xaaab
)
Here is the min/max parameters, as mentioned in the paper that came with the sensor
So any value outside of these range will be incorrect I guess.
I have reinstalled the Z2m Edge on home assistant and I am still seeing the high values every now and then.
How do I check if I have got the changes you applied via z2m Edge in home assistant?
To make it less spammy I recommend debounce or set cache flags to false. https://www.zigbee2mqtt.io/guide/configuration/mqtt.html#mqtt-behaviour
I burned a paper next to mine now. Zero difference on the pm25, still same noise between 3 and 10 units.

I found why the latest install of Z2m Edge yesterday still did not fix the issue at my end. For some reasons, installing the Z2m Edge is pulling a slightly older version of the Dev branch. Pls see the attached screenshot.
Could you please check why it is not pulling the latest fixes?

Thanks a lot !!! The debounce option solved this problem ! I was looking for this for long time ! thanks again !
Hi
I'm not sure it will be enought. Because I agree it will nice for Z2M and HA, they will have only few messages. But I saw that my CC1352-P2 has many issues few days after and I think it's because the Tuya device will spam and 'kill' after few days the stability of the Zigbee coordinator. The zigbee network it self is compromised.
Am I right to think this ?
Since I disconnected the device, I didn't have any issues after that :(
Thank you for your advice on this
It could very well be. It's sending 5 messages every 5 seconds or so. I don't seem to have issues with my CC2652 luckily. It's probably outside the control of zigbee2mqtt since it doesn't seem to have a parameter for how often it should send.
Since I don't get any useful data from the device I will probably disconnect it anyway and I really can't recommend it. Maybe I can use it as a temp/hum sensor...
Thank you for fitering the pm25 values! Now I can at least see the noise
If anyone got any useful data out of the device I'd like to know :D
I still occasionally see pm2.5 values greater than 1000 (more in the range of around 40k or so). Since filtering the pm2.5 values, they have become lot less. And every day or two I run a sql query on the HA database and delete the records with pm2.5 values greater than 1000.
This has helped a lot in seeing the actual values of pm2.5
Next I played around with the debounce setting and tried different numbers (and I have 4 of these Tuya Air Quality devices) .. setting to 1 or 2 didnt make much of a different, so I tried 10 for a few days. Meaning I set the debounce on each of my Tuya air quality devices to 10 and let it run for 3-4 days to see what difference it made. After this period i realised that value of 10 really made the device useless .. the measured values of pm2.5, co2, voc, formaldehyde etc would change once in a few hours .. which made them useless really.
Eventually, after some more trial and error I have settled for a value of 5 or 6 as that slows down the refresh of readings from these devices to roughly once every 30 seconds or so, and I am happy with that.
Hope that helps.
What happened?
Connected a Zigbee-based Tuya AirBox04 sensor to Zigbee2MQTT, the device was detected as a TS0601_air_quality_sensor, and started rapidly reporting sensor values, but the "formaldehyd" value is suspiciously high, and "co2" value is suspiciously low. Comparing the data from this device to a near-identical WiFi-based device, I can tell the VOC is wired up correctly, but co2 and formaldehyde were swapped.
Example message:
What did you expect to happen?
All reported values were correct.
How to reproduce it (minimal and precise)
Pair an AirBox04 device to Zigbee2MQTT, observe logs.
