Home Assistant is open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect to run on a Raspberry Pi or a local server. Available for free at home-assistant.io
I run Home Assistant in Kubernetes. I also use helm, which significantly reduces the amount of config yaml that's necessary for k8s, so it's pretty manageable.
