How do I adjust the polling interval?

I could not figure out how to change the update interval of the sensor. I think it is now at 15 seconds but I don't understand why :)

This will be the median filtering (see https://github.com/trvrnrth/esphome-bsec-bme680/blob/master/src/.bsecsensor.yaml#L60 for temperature for example). For my use case a bit of smoothing and fewer data points was beneficial but you can safely take that filter out entirely if you prefer quicker updates.

Thanks for your reply. Does that mean that the loop in the custom sensor class ( https://github.com/trvrnrth/esphome-bsec-bme680/blob/master/src/bsecsensor.h#L146 ) runs without pause? I don't need quicker updates but prefer slower updates and have in mind that the lifespan of the sensor expands (at least thats what I think 😄).

Yes, the loop runs continually with the BSEC library taking care of keeping track of when to actually next poll the sensor in its run function: https://github.com/trvrnrth/esphome-bsec-bme680/blob/9c5999f60221be149d51697467fc701068cceb49/src/bsecsensor.h#L147

You could provide a different config (see https://github.com/BoschSensortec/BSEC-Arduino-library/tree/c5503e0e85067e07e11b45b4215663f929e640c3/src/config): https://github.com/trvrnrth/esphome-bsec-bme680/blob/9c5999f60221be149d51697467fc701068cceb49/src/bsecsensor.h#L124 https://github.com/trvrnrth/esphome-bsec-bme680/blob/9c5999f60221be149d51697467fc701068cceb49/src/bsecsensor.h#L6

This would allow you to increase the interval to 5 minutes instead of 3 seconds though I couldn't say what impact a longer interval between sensor heat cycles would have on overall lifetime. Typically you'd do so to reduce power requirements / increase battery lifetime.

Thank you a lot! :)
