    why are you using a real time clock if you can get the time over the esp from a ntp Server?

    Good question but there are a few reasons: getting it from an RTC is in fact quicker. Also, when one uses the ESP as a client to get time from an ntp server, but at the same time want it to do something else as a host then that may cause some problems. I am sure it is possible but wouldnt directly know how
