ESPEasy should get the RTC from my RaspberryPi

[themanfrommoon]

Hi,

I have a http://www.volkszaehler.org/ smartmeter logging running on a Raspberry Pi 3.
I have an extension with a RTC connected to the RaspPi.
Then I have several DS18b20 temperature sensors and an OLED display connected to an ESP8266 running with ESPEasy. This collects some temperature values and it sends it to the RaspPi.

Now I want the ESP8266 getting / synchronizing the time from the RaspPi and show it on the display connected to the ESP8266.

Is this possible with ESPEasy?

Thanks and best regards,
Chris

Well, the question is if it is possible with the RasPi.

You will have to use the ntp server from debian/raspian and configure it to your needs.
You will find some info here:
https://www.tecmint.com/install-and-con ... in-debian/
for example or just google for "debian NTP server" or "Raspbian NTP server".
It will give you a lot of results. Be aware that using an own RTC module
needs sometimes tricky adaptions.

I'm running an old Raspi B with a radio clock receiver myself
as a central time source for my network- it works
