Yup, that's correct, though the old library in my repo still works and is used by some folks, maintenance of SoCo is handled by a group of very talented and friendly developers under https://github.com/SoCo/SoCo

It looks like the author used SoCo for the Raspberry Pi project mentioned at the bottom of the article.

Hey Rahim - you did great work on that project. I've used it a few times with an RPi to control my household. Works like a charm!

SoCo was a big inspiration :)
