I love my smartthings. I use the dirt cheap xiaomi sensors (think £4 for a door sensor, £7 for a motion detector), and couple with the ikea bulbs, i now have  cheap automated house. great product.
to avoid having to replace all my lights, i have also installed the xiaomi mains light switches (they dont need a neutral so great for the UK). £22 quid for a double switch that alexa or the smartthings app can talk to.....fantastic
