I've been monitoring my energy consumption, extending my existing doorbell to an upstairs stereo, automatically turning lights on in different modes as I walk around at different times of day, playing a beautiful loon call as the sun sets, securing my home while I'm away (it auto-arms when my phone disconnects from the router and disarms when it returns), turning on a/c when I begin my commute home, reminding me it's garbage day, etc. All locally running on an open source platform with remote access over OpenVPN. This is the wonder of Home Assistant. It's mostly just for fun but you can easily see it becoming very practical. My security system is legit; it emails snapshots from cameras to a special account that triggers a urgent notification on my phone while turning on a loud siren in the home and all the lights. I did a funhouse mode that played static on the tv and monster/police/machine gun noises on the stereo while chaotically blinking all the lights... it actually scared even me a little.
