Using Local Time at odd hours off UTC, wanting to record on even hours




I'm running the following versions (on an AdioMoth 1.0.0)


AudioMoth Time App: 1.0.3

AudioMoth Configuration App: 1.2.1

Firmware: 1.2.0


I set the time with the Time app, then in Configuration App, I check local time. I want to record every two hours for 2 minutes, even hours only.

But when I set this, it instead does odd hours. Presumably the settings are for the UTC time, not the local time? How would I configure it to do every 2 hours, but at even-numbered hours local time, when I'm an odd # of hours off of UTC?



Ah, that's an interesting use case that we hadn't thought of.


AudioMoth uses UTC internally. Since you have a full 24 hour recording period set, this gets turned into a schedule running from 00:00 UTC to 24:00 UTC so you are correct that this will generate schedules that record for 2 mins at the start of all the odd hours (due to the odd offset from UTC).


If set the recording schedule to be 01:00 UTC to 24:00 UTC with the configuration app in UTC mode, and then switch to local time before you actually press the 'Configure AudioMoth' button, you should then get recordings at the start of each even hour, and the timestamps will all be in local time as before.

Thank you, that appears to do the trick, but when I got around to testing this, we had changed daylight savings time. Now I'm UTC -6, so I'll only have this problem half the year!

  • Hi, I have purchased an AudioMoth to detect the ultrasonic sound emitted by bats. And I would like to know how can I detect i) count number of bats ii) bats' flying direction.   I am doing a project to contextualize bat data through different actuators of Arduino. Using LEDs, speakers, motors, etc to visualize bat data. For example, if frequency = 45kHz, LED will light up; if more bats, the motor will spin faster, etc. How can I do that? And can I transfer the data live, and wireless, using a raspberry pi and upload it to the cloud? Again, how can I achieve that?   Finally, is there any guide to manipulating the bat ultrasonic wav. file to human audible sound or visualize through spectrogram? Any tutorial for that? I am trying to use Adobe Audition.   Many Thanks!
  • Hi, I just wanted to check that the AudioMoth should stay with the switch in the USB/OFF position when using the configuration app? Even when you press "Configure AudioMoth" in the app? Then when ready to turn on in the field, change the switch to CUSTOM? Thanks.
  • Hello, I used to record birds (video+sound) as a hobby in my garden using a raspberry pi computer (+ a camera and a microphone attached to the Pi) and a motion detection software. I stumbled upon the audiomoth, ordered one and I wish to record birds for now. What set up should I use? Any advises welcome... Thank you.
