Hi,
Yesterday 15 out of 23 nodes died on the primary controller. I've tried to take power off half minute and still no luck. Secondary controller sees almost all though.
What could have happened to primary controller and what to do. It's 3 years old.
Quite often "Error handling data from server" is shown also.
Many nodes died suddenly

Hi Joachim,
I also had such issues in the last years. They usually occur when I have not rebooted the raspberry pi for a long time. Approximately after 110 days. So far, I was able to rescue all devices, when I renewed the interview manually within the expertUI.
I can imagine that this could be a side effect of the problems with the notification.json (see the other thread)! Which size has this file in your storage folder?
