From the project

Mykilio is the proposal for a new Living Standard with the goal to reimagine infrastructure management and monitoring. It aims to be scalable, lightweight, extensible and secure by applying IoT principles to the datacenter and homelabs.

⚠️ Experimental: This repository is under active development. Usage in production is not advised, but any kind of feedback is welcome.
