I will try to make this clear as I can. If confusing please let me know and I will add more info.
I am using Hometroller Pi w/ HS4 and a few z-wave devices AND local use only (meaning Pi is NOT connected to the Internet except for occasional updating). I do not need or want remote access. Also, I use a surplus router locally to access the HS web interface (it too is NOT connected to the Internet). This allows me to control/adjust events, etc. The Hometroller is connected to a UPS.
My problem is that cccasionally our electricity goes off for extended times (sometimes several hours), exceeding the capacity of the UPS to support the Pi. When power is restored, the Pi does not/cannot reset the clock to the current time and the system time defaults to the time when the Pi Hometroller was shutdown. Obviously this creates problems for my event triggers. It seems the only way I can reset the system time is by connecting the Pi to the Internet and waiting for it to obtain the time (and then correct it for my location - which it does properly). It is not clear to me if the system time for the Pi/HS4 is actually being obtained from the Internet (maybe some NTP server) or from my laptop/desktop which I use to access the Web Interface locally.
Is there a way to reset the clock manually or adjust for this problem manually when it occurs??? Any suggestions/comments would be appreciated.
BTW otherwise the set up works pretty flawlessly as long as there is no power interruption.
