The firmware for this was put together in a hurry, but I am working on a full update to the firmware, using asynchronous background NTP. Perhaps I will mange to finish it this weekend.
For further development: I am considering flipping the board so the components go on the bottom, and moving the Wemos so the antenna is not directly behind the tubes. I think this is a problem for the reception of the WiFi signal.
no problem the clock works that is already good.
I have already outsourced the ESP on the breadboard so I get the update to the time server after every 5th attempt.
Thanks a lot for this.
I'll wait and see what you think about it.
