The first two days or so with my purifiers were great. Low numbers, machines running on low. Great. That made sense, newer (2017) house, MERV 9 furnace filter, air exchanger with a filter as well, clean house, hypoallergenic dog that doesn’t shed, etc. For some reason today both purifiers have basically stayed between 90–180 all day and have been ripping. It might dip down to 140, then 10 seconds later back to 180…with nothing moving or going on. Something doesn’t seem right. Nothing changed at my house. There is no way to reboot the sensors, no way to manually pull air quality updates, and no indication of what is actually going on other than me losing trust in the numbers I am seeing. Ideas?
I’m thinking the front panel display is showing particulate matter, not AQI. Wyze really needs to provide us with all the information, instead of just throwing out a bunch of numbers and not explaining them.
Well, the number on my app (29), doesn’t make the number on my machine (002). But then again the app also shows the AQI was updated an hour and a half ago, yet I never see the 29 number on my machine. I don’t really understand why the app can’t be updated continuously or at least refreshed when the app is opened.
So I checked with another maven and here is his take on it:
I have always understood the the number on the unit to represent what the particle laser has most recently detected, and it will change rapidly as the last detects multiple times per second.
The number in the app is taken from the laser sensor readings but it is polling the device less frequently, either averaging recent detections or just relating the number that happened to the most recent number at the time the device was last polled. I don’t think that this is a set internal though. I think it works more like what the PM said about the aqi graphing… That the frequency can kind of vary depending on state changes of the device.
Now, when you go into the app and click on the light at the top right, you will get to the Insights page and the Indoor AQI History.
The app seems to always show my indoor AQI as 29, even though my Wzye Air Purifier has never shown that number, most often it’s 010 or below. Today the app is again showing the AQI as 29. But polling the machine once every couple of hours, makes the data old and worthless. Right now looking at the Insights page, Indoor AQI History there are no white dots on the graph, I’d think there would be some dots. I only seem to get a dot when I unplug the machine and plug it back in.
Also, can someone tell me what the vertical numbers on the graph, 0 - 500 represent? Because, if it’s supposed to be particulate matter then the PM2.5 Health Guideline dashed green line on it is wrong, as it’s positioned at around 50 on the graph.
And, above the graph the Outdoor Pollutants I have 6 of them showing. It would be nice if Wyze had it so if I pressed one of them that it would explain what they are and what the numbers mean.
Wyze sells us this air purifier with all this data and doesn’t explain what it means. WTH Wyze?!
As someone who has made consumer hardware products, we couldn’t get anyone to read the quick start guide either The AQI description is there on page 7. That’s where I also found the location of the mystery laser sensor, and the distance required from the wall for it to scan properly.
Doesn’t explain HOW the laser sensor works, but I wouldn’t expect that in a QSG.
Now if we can get Wyze to enable a dimming option on the display without having to use night mode, and outside/inside AQI history longer than one day? Wyze vacuum, thermostat, scale, and door lock all have a year history included. Perhaps this hasn’t been a feature request yet…
