I’ve managed to set the timezone to +02:00
I exported the settings to the json file and found the tz value and changed it from 28 (seems to be the default) to 56, saved the file and then imported settings using that file and not my timezone is correct, still can’t set it from the web/app interface anywhere…
Still have the water level not re-calculating issue (and and issue with current day sunrise and sunset times – posted separately)…
