Fitting a timer switch to a 2-way circuit

[TR1CKY]

I probably had the live the wrong way round.

However, I'm a bit puzzled why/how, in the OP, you wrote this - which is wrong - but is in fact the wiring for the timer which has now been done.

What's wrong about it?

Well, it was quoted in the original question as the way to connect a typical two-way circuit but was actually the way to wire the timer.

Seemed odd. Did I misinterpret the intention?

Now, the instructions for a typical two way circuit (5 wires one end 3 the other) say;

Connect live wire to LIVE
Com from other switch to LOAD
L1 from other switch to 2 WAY
Switched LIVE wire to LOAD
L2 on the other switch has no connection and must be isolated by connection block etc.
