Mode 3 should be recording during the day, however if I put the following in SETTINGS.TXT sunRecording: { sunRecordingMode: 3, sunRoundingMinutes: 5, sunriseInterval: {beforeMinutes: 30, afterMinutes: 30}, sunsetInterval: {beforeMinutes: 30, afterMinutes: 30} } I get the following result (from LOG.TXT): Calculated sunrise time is 06:49 UTC and sunset time is 16:58 UTC. Time of first recording is 19/02/2023 16:30:00 UTC and duration is 890 minutes. so this this will be a recording during the whole night (plus 30 minutes before sunset and 30 minutes after sunrise) Mode 4 should be recording during the night, this seem to give a revers result as well: sunRecording: { sunRecordingMode: 4, sunRoundingMinutes: 5, sunriseInterval: {beforeMinutes: 30, afterMinutes: 30}, sunsetInterval: {beforeMinutes: 30, afterMinutes: 30} } Gives: Calculated sunrise time is 06:49 UTC and sunset time is 16:58 UTC. Time of first recording is 19/02/2023 06:20:00 UTC and duration is 670 minutes. For some cases one would like to record a limited period somewhere during the night relative to either sunset or sunrise. In my case for example a period from 3 hours before sunrise until 1 hour before sunrise would be best (balancing the activity of the species of interest and the total amount of Gb's recorded over several weeks). Mode 0 with a negative number for afterMinutes would make this possible i suppose , did not try that yet since negatives are banned. Cheers, Eric

I would like to add GPS functionality to my Audiomoth 1.2.0. boards. This could hopefully be done by making connections to GPIO b9, b10 and a8 (as well as the supply of 3v off course) I am looking at ADA-5440 (Adafruit Ultimate GPS Breakout with GLONASS + GPS - PA1616D) for instance. Might this work? Thanks, Eric
