  So I have got "early ones" from Alibaba. Out of curiosity, I burnt out hole in the up-right corner using needle and now I have correct readings (METAR - elevation for comparison) :)
  Thanks for your help!

  I haven't noticed any hole. I will drill small one :)
  Thank you!

  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
