Home Assistant

Home Assitant is an open-source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect for running on a Raspberry Pi or a local server. The number of integrations that are available in Home Assitant is very impressive, the community is very active, and there are heaps of tutorials available that you can check out to get stuff done.

Like most things open source, there are good tutorials and not so good ones. It's my intention to build a library of information that is more targeted to new or inexperienced users, but I am not going to re-invent the wheel if there is a video of a tutorial that is already pretty good. I will just link to that.
