Ahhh - thats a nice one; I can boot with zones whenever I'm at the GFs (or other locations) house, and use an event to trigger anytime I'm not in a z
I must admit that for me, it's theoretical at the moment. I haven't been  tinkering with HA that much. I recently started using it again since,  well, I  seem to have left the RPi's unattended and somehow they multiplied... Also, I  have now have Ikea stuff too in our new house (besides the Hue stuff we already 
have since ages), so a bit of home automation adds a lot.
Now just to grab a new smart-plug - the couple I had laying around were ol Home Depot offerings in which the company went away and can you believe th didn't even leave the functionality!?!? ... actually, I didn't search HA - maybe theres a way to use them STILL.
I use the ones from Homewizard.com myself. They're not cheap, but feel solid  and can measure power usage as well. I noticed (ofc after I bought those) that  Athom plugs tend to be a lot cheaper. Must say that my purchasing decisions are 
largely based on 'what do I have already', and I already own a p1 and kWh meter 
from Homewizard.
Let me know how it goes!
