I have Raspberry Pi3 with Hass.io installed. I have been working with it for over a month with no problems. Today I had basically finished all my configurations (at least, for now). I rebooted the system and now it seems bricked. I can’t access the Web GUI or SSH, but I can ping it at 192.168.1.111.
Right before this happened I changed an email address under notify settings in configuration.yaml. I wasn’t doing any serious work that could brick it.
I have tried rebooting (unplugging and plugging back in) several times but get the same result.
What can I look at to fix this? If it can’t be fixed and needs to be rebuilt, is there some way I can retrieve snapshots from the SD card? I took a snapshot 15 minutes before this happened, but didn’t save it off the device.
Sounds like you bunged up your yaml. Just pull the sdcard and pop it into a computer (use a Linux distro to access the files) and edit your yaml. You can even look at the log file and verify.
This is why you always have a backup that isn’t ON the device itself. Sdcards are not trust worthy enough
You can access the yaml files to fix the config error using Notepad++ if it has been set up to ssh into your Pi without hassio running. See the video at https://www.youtube.com/watch?v=cQa6DjkY3SY to see how to do it. You can also see the log files which might point to the error.
