0ld home wiring question

I am trying to replace a switch with a digital timer. But this stupid house only has one black and one wire coming from the wall. I am attempting to connect it with a digital timer that has one black one white and ONE RED wire (The ground is present and not the problem) What do I do with the red wire when hardwiring the digital timer???

Sorry but you need some rewiring. The two wires on the old switch would be connected to the black and red on the timer and you need a common for the timer to work.

What does the manufacturer say? Some devices got UL approval even when they used the EGC to power the electronics, when a neutral was not present.

Such was the case with Occupancy Sensors. Using the bare, rather than a neutral,imposed about .5/1000 of an amp on the ground, which was deemed OK, at the time.
