If you live in US and in the state that observes Daylight Savings Time or DST, get ready to set your clocks back 1 hour this Sunday …  or not!

We’ve done some testing on the V3 firmware and squashed several serious bugs and added new features


  • Hours incorrect in 12 hour mode and AM dot not showing up
  • Date always showing in UTC timezone

New Feature:

  • Added UTC Timezone if you leave in state or country that doesn’t observe DST.

Version 3.03 is out now on our github repository.

Upload it to your Xronos 2 Clocks, set your Timezone and watch clock change time automatically on Sunday!

Note that this version will work even if you have DS3231 time chip upgrade (there’s no longer separate version for that!).
Also you will need to re-adjust your time after setting Time Zone for the first time. Clock will now reboot itself after important settings was changed (like time zone or RFM).

Enjoy, and let us know if you see any issues!
