The measured gas resistance starts low for a new BME680, then it increases until it is always the same. This value then never changes again, any suggestion where this is comming from is appriciated. I've seen this behaviour now at two bme680's. The temperature, humidity and pressure are changing almost every measurement. Init values used (in python): sensor.set_humidity_oversample(bme680.OS_2X) sensor.set_pressure_oversample(bme680.OS_4X) sensor.set_temperature_oversample(bme680.OS_8X) sensor.set_filter(bme680.FILTER_SIZE_3) sensor.set_gas_status(bme680.ENABLE_GAS_MEAS) sensor.set_gas_heater_temperature(320) sensor.set_gas_heater_duration(150) sensor.select_gas_heater_profile(0) sensor.get_sensor_data() sensor.data.gas_stable True "{} C, {} hPa, {} RH, {} RES,".format(sensor.data.temperature,sensor.data.pressure,sensor.data.humidity,sensor.data.gas_resistance) '25.79 C, 1024.7 hPa, 32.167 RH, 9186214.0 RES,' '25.76 C, 1024.7 hPa, 37.694 RH, 9186214.0 RES,' '25.74 C, 1024.72 hPa, 37.636 RH, 9186214.0 RES,' And so on...
