Apologies but for some reason i just cant get my head around Smartthings.

At the minute i have Evohome and i use Life360 and IFTTT to turn the heating on and off when people leave the house. However it doesnt work well enough, it often takes hours to get the signal that someone has arrived home.

Can Smartthings do it better. I want the heating to come on should anyone come home, and off when everyone leaves.

I also want at some point some CCTV cameras mainly for the front watching the cars, it would be great if these all tied into the same smart system.

Also getting an Amazon Echo soon and Philips Hue lights. The bit i dont get is Alexa can talk directly to Hue so why the Smartthings?
