I have a very strange timer issue. I have 16 timers setup with 4 of them set to trigger at 30 minutes before sunset. All the timers work perfectly except for *one* of the timers that is set to sunset-30. That timer is supposed to turn on a lamp in my office. I have another timer that turns the lamp on in the monring and that works fine. I have tried deleting the timer and re-creating it but that didn’t work. I have deleted the device and re-establsihed all 4 timers associated with this device. The three timers associated with a particular time work fine, the sunset-30 timer o this lamp simply will not fire. Help!
