My recent idea is, that I received device with tightly-closed sensor without contact with environment.
Yes, that is most probably the problem. They later added small hole on the top side where the strap is. If you have no hole there the watch is a bit more waterproof but you get pressure inside watch not outside. Also search the forum here, there are more details, some early Bangle 2 watches are like that too. I also have such Q3 without hole and can confirm it behaves like that.

Hi,
I bought SMAQ3 directly from Alibaba. I built espruino version: 2v14 and now I'm trying to read pressure.
First impression was like I get correct values but when I keep watch in hand, pressure increases along with temperature. I have seen that pressure correction is calculated inside the source code. I have tested it as well with ZephyrOS + BME/BMP280 driver and I got similar result. My recent idea is, that I received device with tightly-closed sensor without contact with environment.
Did anybody struggle with this problem?
Best regards,
Jacek
