any chance to implement NTP so that the inverter can not drift in time..

[d0m1n1qu3]

this is a feature request ;-)

I use a MIC-600-TL-X and founds out that the time is not so stable..

may be ther e is a chance to set the date and time via modbus and the shinestick or ESP get it first via NTP from the internet router

best regards d0m1n1qu3

This sounds like an interesting option. It might get complicated due to handling of timezones and DST. Are you defining fixed timeslots for AC charging or are you dynamically controlling the timeslots anyway? If you have a logic to push dynamic settings from external it might be much easier to just update the time from that source as well.

I have to correct my previous post. Its actually pretty simple. The code is not very nice yet, but it works for me. If you can compile the firmware yourself I can upload a draft patch that you could test.
