Pimatic no connection (XHR Poll Error)

---

Yes, I can reach SSH.
Connected is a self built Nanocul and a Printer. But the Printer is manly powered off and has no energy, only when needed.
I’m running a CUPS for that printer on the Pi too.

About WiFi, found out now that there is a power save option active by default. I set it now to off.

I have the same issue, and are running on a wired Ethernet connection

I used monit to monitor pimatic, when it doesn’t respond anymore it is restarted automatically. But I prefer to have it running without this off course.

The problem occured again. I noticed now that the Pi dosn’t work at all. No SSH and the ACT LED dosn’t flash.

@dasmaetthes for testing purpose, remove all usb devices attached and see if it stays on.

maybe a corrupted memory card?

Without any USB device the same happens.
Made yesterday also a fresh install again on new memory card. But didn’t help. Now the problem occures even more often.

Will try next week an other Pi.

Are you able to measure the Voltage of the Pi?
If yes, measure Pin 1 against Pin 39 and Pin 2 against Pin 39

Changed the Pi and SD-Cardand made a new setup of pimatic. Now all works well last days.

The issues I had seem to be gone. I did some changes so I’m not sure which one solved it, but disabling the calendar plugin was one of them. I think I’ve seen reports with unstable installations where this plugin was also installed.
Hope this helps someone.

For me this was solved by deleting the browser cache
