Hi,
First advise: never update DSM to the latest version the first week.
That gives us some time to test it ourselves and make fixes if needed.
Synology never gives us updates in advance, so we always need to find out afterwards.
Second advise: Inside PulseStation administration panel, go to Add-ons and install the “Backup” service. Refresh the page.
Then go to the Services menu on the left and click on Backup.
You can now create manual backups, the same way you would add devices, with the button on the right. I do recommend giving every backup an easy to recognize name.
You can also restore backups with this service.
Third advise: I’ve never had to reinstall PulseStation after an update of either DSM or PulseStation itself.
Why do you think you need to reinstall PulseStation? Does something always stop working?
Then for the permission problem:
Option 1) Try to reboot your Synology and check whether the key becomes available again
Option 2) Check using the dmesg command from our faq whether the key is still on that port, maybe it’s changed. Then change it inside the PulseStation zwave service configuration.
Option 3) Once you know the correct port you can try following command:
chmod 777 /dev/name-of-your-port
This should work. If still not, I wouldn’t really know how to fix it.
Maybe we can look together via live chat then…
