Title: Battery Backup
Post by: normd on December 01, 2018, 05:46:11 PM
Since the WM100 has a major design flaw in that it cannot retain the time during a Power Failure, I pugged it into a computer battery UPS.  It sends signals just fine. Just more expense to get this expensive and poorly designed device to work properly.

That's certainly another way to do it.
I haven't had much luck with X10 signals passing backward out of a UPS. Did you test that when the UPS switches to battery, and then switches back, that the time isn't lost? Did you run it long enough to verify that it doesn't gain or lose time while on battery (depending on the design of the clock, the backup power sometimes is slightly off in frequency - enough to mess with clocks).
