I have a RPi3 running hass.io that has been working fine. But then my internet connection broke after a power outage a couple of days ago. After some reboots, Home Assistant is working fine, but I noticed my time-based automations weren’t working.
I logged on using ssh and ran the date command and noticed that it thought it was Juny 23, 2018 and a different time of day.
I’m surprised that it can’t even remember the dates between reboots without haing access to an ntp server. Is this really expected?
I tried setting the date/time manually using the date command, but it wouldn’t let me.
I guess I could try to make it talk to a local ntp server, also without internet connection, but that’s mostly a workaround.
A couple of related threads, but they’re note really describing the same issue:
So how does adding an RTC help in this case? I have an RPI with HA installed at a remote location which looses power often and has no internet. There is local WIFI and two other RPIs with RTCs. In theory I can remote SSH to one of the other RPIs to get the time, but the ‘date -s “time”’ is not permitted on the HA platform so I’m no further ahead.
