I see "wi fi connected" seems like a default choice now, not even questioning. I had one such CO2 detector, but then I realized that anyone gaining access to it (any employee of the manufacturer, for example) can know exactly when we are at home, when we are not, when we go to bed, when we go on vacation etc.
So I disconnected it, bought a $70 device that measures everything pretty accurately and am happy ever since.
- therealdrag0 4y agoWhich 70$ device? I also have one in that range and I don’t trust it.
- EVa5I7bHFq9mnYK 4y agoIt's called Dienmern model DM72B, from Aliexpress, I compared its temperature, humidity and CO2 measurements with other devices and found them correct; as for PM2.5, HCHO and TVOC, I didn't calibrate, but they seem reasonable and detect smoke/farts immediately.
