I recently started looking into air quality and ways to improve it in my home. But it is hard to find a device that integrates in HE and has also high quality sensors.
I,would love to hear if you are using sensors, which devices, which sensor types: CO, CO2, tVOCs, PM, etc and your experiences.
Trying to avoid on my side another rabbit hole ending up with bunch of useless overpriced devices, so any help and advice is welcome.
I have a Ikea Vindstyrka. I am only using temp for rules at present, but hope to use some other capabilities of it soon, just not sure what/how yet.
The newest Air Gradient sensors are pretty nice and technically can be expanded. I have a driver that fully integrates with them.
It has a pm sensor that reports pm 10, 2.5, and a smaller value as well, temp, humidity, tvoc, and NOX, co2.
The it also has a local display to show current values and a lightbard to give you visual cues.
The only senaor it is missing that i would like to see is radon, but in my research that is darn near impossible to find.
Airthings have radon and an HE integration...
i’m going to have a slight bias, but purpleair devices work great with hubitat, no cloud needed.
Ecowitt is not cheap but has many nice sensors including air quality sensor. There is a nice HE driver and integration is 100% local. You will need a Gateway (there are few different including one with LCD screen) and whatever sensors you may like.
That is the only one I know of, but they were really pricy last time i looked. I do know it is good though
It is also important to be aware of values that are calculated vs something real and physical. DEW point, and AQI are calculated values. Technically anything that has temp and humidity can provide dew point. AQI is one of those things that the calculation for it changes by regions as well as the sensors in the device. Personally i wouldn't put to much in those.
So that 3 options that are all local.
Would that mean i can skip over tVOC as that is also a metric re caluclated every 24 hours?
I have temp and humidity sensors everywhere, i would love to get CO2 as well in most rooms.
What would you recommend that can have a great impact on the air quality? Not the metric, but the actual benefit to humans.
Perhaps, but i think it is calculated in the sensor itself based on what voc's the sensor detects. There are allot od potential voc's so it would be near impossible to have a sensor for all of them.
All of the options mentioned are good. Personally i think the PM sensors and VOC's are most relevant for us to have comfortable air quality. Co2 is nice if your air can get stagnant and you spend allot of time in enclosed spaces. High co2 can cause you to get a cloudy head as it starts become impactful.
