Still struggling to get it right. Its wired up but not working. I
just checked the connections but I'm going to re-check for the hot
wire at both ends (hot/main and leg/remote) so I can confirm its wired
according to the instruction. It really doesn't seem to be that hard
but obviously I'm wrong. One thing tho, the remote switch didn't
have a ground terminal so the ground in the box (plastic) is wired
together but not connected to this remote switch. Can this ground not
connected to this remote switch cause me not to have a working timer?



If it helps any the schematic (see ST01c) is here....

Still wondering why if I have it hooked up their way, it doesn't work.
I think my connections are tight and I know which wire is hot at both
switches. I know this is stupid to ask but I'll ask anyway.... any
chance it could be wired differently than shown?


I would suggest you take all the wires loose and mark them one at a
time.

With all the wires disconnected find the one and only hot wire. If
you have that, mark that wire with black tape.

Hopefully the other two wires will be different colors. Put a 3-way
back on that group of 3 wires.

Go to the other switch and hopefully you will see the same two color
wires at that box. By toggling the first 3 way switch, find the wire
that is never hot and mark it with black tape and, for now, put the
other 3 way switch back on.

Does everything work like it did before you started?
