We should have a neutral wire running to every power point if we are considering HA in the future....
Devices like Z-wave requires a neutral connection..there are other devices that don't need a neutral but it would be easy to run a neutral during wiring to future proof... I need to find out how much it going to cost me (if any)...
I asked this in my electrical appointment and they said they have neutral wire on all their electrical cables but that is in Sydney so double check.
