Like the quest for perfect weather itself, looking for the perfect weather app can sometimes feel neverending.- Serenity Caldwell
After I got my Nest last year I wrote a fun little script that checked the outside temperature (Forecast.io) versus the inside temperature (Nest) and told me if it was a good idea to open my windows. Nest didn't have a public API at this point, so it was using hacks against the website URL to make it happen. Since then, Nest released a real API and I got around to updating the script.
I had to think through how I wanted to write it. What I wanted to do was write a Swift script to make the updates, but with both kiddos in my life I have a hard time imagining when I'll find time to figure out how to write a Swift app. So instead I busted out Perl, my old faithful, and go to work. It only took a few days to make the updates.
Now it's all working beautifully. It pushes Growls to my computer which pushes Prowls to my phone which pushes to my watch. Wonderful.
