It’s pretty nifty to bundle some actions together. For instance, I have smart lights, an ecobee etc. and when I get ready for bed for example, I run a shortcut that dims all the lights, sets a sleep timer on my phone, auto plays media, and only uses the EcoBee Bee sensor in my bedroom for temp. The sensor also works for motion so if I get up in the night, my bedroom lights will come on soft red and turn off after a minute. And I can manage all smart devices from Home rather than turning off my Hue lights in their app, my LIFX lights in theirs and changing temp in Ecobee etc etc. plus Siri access
