I have a sunsmart GE digital timer switch. It can be installed as either single pole or 3way. I am removing a single pole with only two black wires. I looked at the new device diagram and it looks like I wired it perfectly but there are no signs of life. The new switch has wires: green (ground) white, red (capped) black and blue. The diagram is attached. I'm sure I'm just missing something very simple. Can you help with a better diagram or thought? by the way the switch is in the same box as another 3way but it looks like they are on separate lines so I did not interconnect the two switches.
