Newbie question - what to use?

Hi. My name is Javi and im new into this world, so apologies if the question is dumb…

I want to install at home smart light switches with motion sensor. I have heard that one of the recommended options is doing it with home assistant.

Has anybody created a project like this? If so, can you share info on which sensors, which switch etc… have you bought?

I already have a particle photon, which i understand can work with google assistant, isnt it?

Thanks

Welcome!
Could you specify for us what kind of wires do you have?
There are wall switches that require both live and zero wires, and there are some which can work only on live wire:)

Hi

Im not sure… I am spanish but i live in the UK and im pretty sure no neutral wires are installed here, so lets assume i have no neutral wire
