Nice component. Would it be possible to take into account ozone and sulfur dioxide?

With this setup are you still using the interval so you only turn on measurement for 20s every 2 minutes or do you measure air quality continuous?
My live versions are very close to what I shared previously. I have like six of them all over my house. They measure continuously but I primarily use the rolling data because of the inaccuracy of the instantaneous data. Noise doesnāt help anyone make a decision.
If you look at āofficial AQI numberā reporting, youāll see that the average is rolled by 24 hours which causes significant delay in reportingā¦ it takes a long time to move the needle when a nasty air front moves in quickly. With a 30 minute rolled average the results are nearly real time by comparison.
I have great visibility to see the quality of the air from my house and now I can align what I see with what is actually happening. Mostly I wanted i know: is it just fog in the valley or is it bad air and we should stay inside? The AQI sensor tells me.
I also use the room-based data to trigger air purifiers that I have in the house should the roomās air quality start to degrade. I throttle the purifier based on how ābadā the AQI measurement is. It works very well.

Woah, I just noticed that ESPHomeās integration for PMS5003ST and PMS5003S now have support for formaldehyde! Lately, Iāve been trying to register my 3D printerās impact to room air quality with the PMS7003 sensors I bought but nothing seems to register ā even TVOC/CO2. I know that printing ABS generates formaldehyde (which is pretty much all I print) so Iām going to get a couple of these PMS5003ST sensors and see what it can see.

I just installed and got this working. I love this component, but I am not a programmer. The Indoor air quality UK component makes use of a function that has been depreciated and will soon no longer function. It looks like there is a replacement available. Is there any chance you will be updating this component before it stops working?
This is the Home assistant log message:
Logger: homeassistant.helpers.frame Source: helpers/frame.py:77 First occurred: 7:50:15 AM (1 occurrences) Last logged: 7:50:15 AM
Detected integration that uses temperature utility. This is deprecated since 2022.10 and will stop working in Home Assistant 2023.4, it should be updated to use unit_conversion.TemperatureConverter instead. Please report issue to the custom integration author for iaquk using this method at custom_components/iaquk/__init__.py, line 355: value = convert_temperature(value, entity_unit, TEMP_CELSIUS)
I would really appreciate your help keeping this component alive.

Nice work, but my sensors are coming up as sensor.unnamed_device.
I donāt believe I missed a step in the config, did i?
iaquk:
livingroom:
name: "iaq Living Room"
sources:
temperature: sensor.woonkamer_temperature
humidity: sensor.woonkamer_humidity
co2: sensor.livingsensor_co2_value
Any update on making this work with 2023.6?
Thank you so much @FredTheFrog! With your comment, you saved my day! I spend a couple of days trying to set up the sensor and after connecting the WAKE pin to GROUND, everything worked! Thanks!

Googling the error gets me another thread about another integration, and it looks like that module was deprecated a year ago, not sure if that helps?

I have the same issue. Did you find a solution?
Hi
Sorry, a real noob question
I added the following in the configuration.yaml file, how do I about getting the outputs on my homepage. I searched all the entities and sensors on the system cannot find iaq_level any where.
iaquk:
sources:
temperature: sensor.dyson_purifier_big_quiet_temperature
humidity: sensor.dyson_purifier_big_quiet_humidity
co2: sensor.dyson_purifier_big_quiet_carbon_dioxide
no2: sensor.dyson_purifier_big_quiet_nitrogen_dioxide_index
hcho: sensor.dyson_purifier_big_quiet_hcho
pm:
- sensor.dyson_purifier_big_quiet_pm_2_5
- sensor.dyson_purifier_big_quiet_pm_10
voc_index: sensor.dyson_purifier_big_quiet_volatile_organic_compounds_index
sensors:
- iaq_level
- iaq_index
WARNING: about JQ1/2/300 sensors: these donāt measure what you think they measure
Internally they have a sanyo dust sensor, Alcohol sensor and temp/humidity sensor
TVOC is used to calculate HCHO and eCO2 - the actual MCU on these devices only outputs TVOC data and all the calculations are made in the cloud
About the only thing these are good for is indicating when to open a window.
I certainly wouldnāt regard them as ācalibratedā (although itās possible to do so if you install esphome on them, youāll only get temp/hum/PM2.5/TVOC)
Unfortunately this is the case for a lot of the cheap Chinese sensors. None of the āTuya N-in-1 sensorsā based around the ZN-2C0x series boards have CO2 sensors and whilst itās possible to obtain CO readings from a TVOC sensor this isnāt being done and is merely inferred (TVOC/HCHO/CO/CO2 all track linearly if you graph them)
I regard these units as dangerous. They give false positives AND false negatives on CO levels(*), which may cause the average user to gain a false sense of security
(*) They donāt respond to elevated CO at all, but report lethal levels if exposed to alcohol fumes
Search for āha iaqukā in HACS. The name has changed or that happened with the hacs 2.0 update?!
Thanks for that component!!!
