I recently had a bunch more Z-Wave components installed to give me control over even more lights around the house but still have a few more to go. Really looking forward to making use of 'scenes' and being able to say things like "I'm home" or "bedtime" and have the lights do magical things to make my life easier and hopefully get my electricity bill down a bit (or a lot).

For anyone with home automation installed in your house, what's the most useful thing you're using it for?
