I've an airthings (https://shop.airthings.com/GB_EN/view-pollution.html https://shop.airthings.com/GB_EN/view-pollution.html) sensor, which measures a bunch of things. The pressure is constantly less than 1000 hPa (after 1 year of having the device, not once was higher (I live at 100 m msl) so it must be higher. When I reported the problem, the technical support said "we use Bosch Sensors, so it is impossible that they are wrong". Not only the service is trash, but also the whole interface, which requires permanent internet connection. You can access from your phone the status of the air at your home from anywhere in the world... my fear is if anybody else also can. Notably, after 1 year, there was no SW update... I really doubt the device is safe. I only have it because of Radon measurements. And I hope they are at least more or less ok.
