@benjojo Ah yes, "The Great Ca-Chunking."

@benjojo And there you see the precision of NTP controlled devices.

@benjojo Adding random delays to that kind of switching is so important and so often overlooked.

@benjojo This is the reason, why all my programmed actions are 3-9 Minutes around the full hour.

@benjojo a Lot of thag might also be caused by the Energy market but i heard the moved onn, away from a fixed 60minutes grid

@nicoduck @benjojo yes it's probably market-related rather than a load of loads switching on at once.

Specifically, HVDC interconnectors usually only change their flow on 30min boundaries which can cause fairly noticeable frequency shifts.
