I Have been running this combination for several years now and I'm getting some odd occurrences. any timers that i have entered in the past i cant update, for example i have a timer to turn a light on at 6AM and off at 7, it goes on at 5 and off at 6, the time is correct on the interface and on pro, cant change it. new timers are now going on and off at odd times. is this an indication that the batteries are getting weak and can i changes them?
