Is there one?
Post must be at least …
What on Earth is this?
I do not think there is supported Real Time Clock module for HAOS, but maybe you should make a Feature Request for that.
The Yellow has a RTC, so maybe ? Why would they design it with a RTC, and not support it ?
Ok, I did not check Yellow, but earlier there were no built-in RTC and the modules you can buy require code embedded and have different connections depending on which vendor you get them from.
