[Best Buy] uHoo Indoor 9-in-1 Air Quality Smart Sensor - $329.99

If you've been considering this VERY expensive indoor air quality monitor, now may be a good time to purchase it. This is the lowest I've seen it in two years in Canada. Regular price on Best Buy is $379.99 (although I'm pretty sure it was $349.99 a few months ago). Its $509.99 at Wayfair and we won't discuss how much Amazon is asking for it. It sits around $329US on international sites.

I was one of the original backers of the project so here's my thoughts on it.

It hasn't been updated in 4 years but the sensors are still amongst the best. The dust sensor is a $4 Sharp GP2Y1010 but they've done a good job in calibrating it to be close to a Plantower PMSx003. The data is entirely cloud based, so once the company goes, this unit is useless. No one has bothered to create another server/hack the API due to the price.

The only other device close to this is the Wynd Halo. Unforunately, Wynd's app is not as polished as Uhoo.

Thanks for the info. I'd also been watching the Awair Element 2 (which hasn't in stock for Canada for a while) but didn't know of the existence of the Wynd Halo. I'll have to look into it since it's less expensive than the uHoo and similarly priced to the Awair.

What kind of air quality does this detect. Is Radon included?

I think the important thing is to ask what you're going to use the information for. There are cheaper alternatives and some cheap DIY options. I have a big collection of air quality stuff just for curiosity's sake. Most of the "tips" associated with the elevated levels of pollutants are either obvious or pointless. For example, high CO2 or VOC can be resolved by opening a window but obviously doesn't work in most of Canada for around 6 months of the year.

The Wynd Halo coordinates with the Wynd Purifier, so it can automatically change fan speeds. Using my kill-a-watt, the energy difference is minimal between low and medium, so I always run it on medium. It'll actually speed up to max if the Halo detects low air quality. Uhoo requires IFTTT to do this. Right now, Wynd has not updated the firmware on the Halo to be able to detect pollen, dander, smog, etc. The Halo is using their own custom dust sensor that's supposed to be able to figure out what particles are in the air and use "AI" in addition to the time of the year to increase accuracy. Although there's a light and noise sensor, these are not present in the app. Again, these 2 elements really aren't that useful. The noise sensor also had a floor of 70db, so it was rather useless. The light sensor in the latest update was improved significantly, but it's utility is suspect. Do you care that it wasn't as bright in your room from 13h30-14h15?

Both apps also do not allow sensor offsets, so uHoo shows my barometric pressure in the 960kpa range, equivalent to being in a constant F2/F3 hurricane.. Only Wynd offers data export.

Every few weeks, Wynd sends out an email with some promos, so I can let you know if you want to buy one.

Thanks for all the info. I've been watching over the last couple of years different models but reviews are often not that useful. It's good to hear from someone who has experience in the area. I don't think I'd order one directly from Wynd because unless they ship via USPS the brokerage fees could be quite high. The coordination between the Halo and the air purifier wouldn't likely be something I would use because I already own an air purifier from a different brand. The uHoo isn't one I want but I guess if someone wants it, it's at a good price.
