Hi, i'm developing an air qualiry logger using BME680 and BSEC 1.4.8.0 lite library. Every 5 minutes the logger collects data from sensor and sends them to a server. The sensor is configured to work in ULP (with generic_18v_300s_4d configuration) and has iaq/s-iaq/co2eq/breath-voc/gas percentage enabled. After some days i get following data: The strange thing is that i get accuracy 3 and reasonable data on 01.10.2022-10:06., after i get samples with accuracy 2 (medium accuracy: auto-trimming ongoing) and "strange" values (at least to me!): Tiemstamp: 01.10.2022 10:11 iaq = 25.0 s-iaq=25.0 co2-eq: 500 ppm breath-voc: 0.5ppm gas-perc: 0.0% Is this correct? Is normal go back to accuracy 2 for some time with those values? Thanks, Alessandro
