excellent! Thanks very much
Well Iāve just got every running on the new HASSos restarted and now I canāt get it to load.
I can access the files and the log yet the page is a no go.
Has one come across this?
I did a snapshot on the old system, installed HassOS and then āselect and restoreā snapshot. Now the Pi has been unreachable for an hour. Is that normal or should I try to pull the plug and see what happens?
Make sure you are only restoring files and add-ons. You canāt restore the old HA backā¦
Okay, will try that. I did pull the plug and that certainly didnāt help so is installing af fresh version again. Then I will remove the check mark in the Home Assistant 0.74 box and only choose the rest, and see if that is working.
What does this mean???
I always restore a full snapshotā¦ it only contains configuration information.
Have you tried checking the logs? Depending on how old the snapshot is you might see a bunch of database errors. Try deleting the database and use ssh to restart. Avoid pulling the plug at all costs.
I think itās quite obvious. Every snapshot has 3 parts: Home Assistant, Folders and Files.
If you restore your snapshot (in the image 0.73.0 - ResinOS based) and choose the Home Assistant part, youāll be overwriting your current HA files that are HassOS based.
The OS is independent of HA. ResinOS/HassOS no difference with HA.
In fact itās probably advantageous to import HA as well and then upgrade to avoid conflicts of using old add-on settings with new HAā¦ although it probably doesnāt make any difference.
The recommended manner of upgrading from ResinOS to HassOS is to backup and restore a snapshot without any caveats I have seen.
@DavidFW1960 your answer makes total sense. But in my experience the only way i could get HA to work correctly was the one i mentioned (restore snapshot only for files and addons).
I updated without setting the checkmark in HA itself and it restored, but when it was online it returned a lot of errors, so I tried once again to do a full restore and then just wait. It ended by booting up again and now everything is working as usual again, including bluetooth, so thats great 
Normally if you get errors after restoring a snapshot, deleting the database will fix it in my experience.
I have also had odd results if I restore a snapshot to a working and already configured HA instance (with add-ons etc). However I have never had an issue with a clean install (after deleting the database).
On from what David says, unless you know what you did wrong, deleting the database in any instance of HA not starting up is a good starting point, itās surprisingly easy to corrupt.
I did delete the database and that fixed the history and log being empty. So a full restore and deletion of database worked for me.
So, thinking of upgrading my Pi to HassOS. Will use a new SD card. Current will be kept as backup.
So etcher and hassio (HassOS) on new sd card.
Insert in pi 3b.
Boot.
Install samba addon.
Move full backup snapshot to pi.
Restore snapshot (folders and addons). Wipe and restore?
Delete db
Restart HA.
Thatās it?
Best regards.
That will do it yes
So Iāve just flashed my Pi2 with a brand new image of HassOS, latest version. It boots (eventually) and loads the screen, but I cannot get to any of the āHass.ioā section. I click on the link and it just shows a blank white page. I have no way of getting onto the box at all; I canāt install the SSH, SCP, Samba or Terminal add-ons, because the page doesnāt exist. I also canāt load my old snapshot for the same reason. Anyone else have this problem or know how to fix it?
I had a similar problem when I was running a Pi NAS using the 3v3 rail from a PC power supply that was also running the HDD. The 5v rail was rated at 15-amps, so I was totally unexpecting āundervoltageā warnings. The problem, it turned out, was the micro SD cable that I was powering the Raspberry from. In this case I solved it temporarily by using a 1A wall-wart supply. The permanent fix was to hard-wire the 5V from the PC supply into the Raspberry.
