wow, the temtop website sent my laptop fans spinning with all the crap it tries to load, and that my content blockers went into overdrive blocking (especially, and inexplicably, from reviewsimportify.com).

still, i'm interested in getting a good pm2.5 monitor to pair with my air purifier, as air pollution is a much bigger issue than covid (air pollution certainly affects vast swaths of people across the world, persistently and largely invisibly, and is only getting worse over the decades).

is waiting for the wifi version (currently sold out) worth nearly twice the (sale) price of an m10?

The WiFi versions have negative value to me, the apps are usually terrible and they are almost impossible to pair (typically only have 2.4ghz radios).

I went with the P10 which does exactly what I want (AQI and PM2.5). It looks nice, it works, and is highly visible from a distance (even has a 6hr battery which makes it easy to move between rooms).

The only other one I'd consider is the one that does CO2.

As a bonus the Temtop sensors are less than half the price of their competitors while being at least twice as good.

i guess i should have been more specific with my non-wifi version questions:

* is there a way to view sensor data historically and arbitrarily, preferably off device?

* is there a way to use it to control other devices (possibly via a home automation gateway) like my air purifier?

i see that it can be plugged in for power, but also has a battery, which is a nice feature. does that also allow for data transfer?

It doesn't do any of those things, it just senses AQI, PM 2.5 and puts it on the screen.

My experience with the devices that attempt to do the things you want is that they suck.

They do each of those things poorly and their basic detection functionality (most important feature) is also bad. (The reddit thread I linked to has details).

If a device existed that did those things and was actually good I'd recommend it.

As it is, everything in the market is awful.

At least these Temtops have the basic functionality down and do that part really well.

If you can do some really basic soldering then any i2c capable board (like raspberry) + PMSA003I + ccs811 and influx+grafana or something to dump the data into shoule give you the monitoring+archive solution.

Now just put your laptop inside of a HEPA vacuum bag. Problem solved.
