BEM280 sensor readings and offsets

### Discussed in https://github.com/AllskyTeam/allsky/discussions/5082 <div type='discussions-op-text'> ^{Originally posted by **takingalook** February 17, 2026} Are these temp/humidity/pressure readings from the BEM280 sensor? I'd like to calibrate the pressure for my altitude, but i don't see a py file to adjust for this, nor is there a forumula in Overlay Editor. Is there any way to 'calbirate'/offset sensor readings? Am i using the right variables? I've wired and confirmed connection to the BME280 in I2C (76)  </div>
