Hi josemartinez,
Hardware: The heat source will affect the temperature and humidity. What about your hardware layout?
Software: 1. If you use BME680, you can use BSEC Orduino library(https://github.com/BoschSensortec/BSEC-Arduino-library ). If you use BME688, we suggest you use Bosch BSEC2 Library( https://github.com/BoschSensortec/Bosch-BSEC2-Library/blob/master/examples/generic_examples/basic_config_state/basic_config_state.ino)
2. For your feedback "The problem is that temperature that is reading, the compensated one, is over 3 degrees up than the real and humidity is like a 60% lower. CO2 levels seems to be unrealistic too.", is your temperature and humidity value RAW data of BME688 or the temperature and humidity value output by BSEC?
