Actually I dun think our SG wiring is plug and play with such smart switches in the first place. The extra wire should a direct live wire bypassing the looping circuit.

In my opinion, if you have 2-way switches, you really only need to replace 1 of them with a smart switch.

In my home I do not have any 2-way switches and I only replaced those switches that I would foresee being used frequently. For e.g. my storeroom light is still controlled by a "dumb" switch

By right in our SG context, our wiring should follow the UK standard but seems like topherw86 's 2-way is done the 'EU" standard, with only one wire for the 2-way connection.
