I'm looking to set up an AC 240-volt lighting circuit consisting of two lights (let's call them L1 and L2), a standard switch (SW1) and a PIR.
The goal is to have SW1 turn on only L1, but if the PIR activates, to have it turn on both L1 + L2.
In my attempt so far, I've effectively created a standard 2-way circuit, but that has the unintended behavior that either the PIR or SW1 turn on both L1 and L2.
Is this possible using only these components, or is there some other component required to make this work?
Context: SW1 is an internal switch, and the PIR is outside. L1 are lights in the soffit of a building, and L2 is a security floodlight.
Table 1. (For OP to edit.)
