Just get back on your schedule. Use cheaper analog timers or mechanical timers. I swear to God. At my age I have used it all. Digital equipment screws up way before cheaper analog mechanical devices. Therefore it is less dependable. The best switch is somebody who actually does the turning Off/On. Otherwise use heavy duty mechanical units. And replace them before they screw up. A switch only has X number of times it can turn "Off/On" before contact wear makes the switch less and less reliable. In other words, buy one a year and don't cry about it. Cheap insurance. Used your old ones for burglar duty on lamps in your house.
