Newbie to Smartthings

Hi All,

I have been looking more and more into using the hub and looking for advice for a number of items

Smartthings Hub vs Amazon Echo Plus (not tied to brands so more than happy for Google Home)

Door/Window Locks - which model
Motion Sensor’s
LED Lights (bulbs) inc Light Strips for kitchen,bedroom & behind TV
i know this is UK but open to items from elsewhere if i require to order adaptors etc

All items i am hoping to be cost effective as possible.

I would also like to automate a number of items i.e. open front door certain lights come on, enter room lights come on (dont believe this is possible with the Echo Dot Plus)

Hoping for a bit of advice from you around this and open to suggestions.
