DomeCtrl's ControlBox puts radiant floor heating and lighting on a Raspberry Pi 5 brain

DomeCtrl's ControlBox is a crowdfunded hardware solution that packages a Raspberry Pi 5 into a dedicated controller for home automation, with a specific focus on managing hydronic radiant floor heating systems. It runs Home Assistant out of the box and is designed to interface directly with thermal valves, hydraulic pumps, and 1-Wire temperature sensors over long cable runs, aiming to replace multiple standalone controllers. Beyond heating, the system expands into general home control with substantial capacity for LED lighting (supporting up to 2 kW of output across 32 channels), wireless peripheral integration via 433 MHz, and control of other energy devices like solar panels or heat pumps. For engineers and DIY smart home enthusiasts, this represents a consolidated, open-platform alternative to proprietary vendor ecosystems, bundling robust I/O (optically isolated GPIO, PWM, solid-state relay outputs) with the flexibility of Home Assistant and ESPHome. The takeaway is a highly specialized, capable bridge between the maker-friendly Raspberry Pi ecosystem and the demanding, real-world requirements of whole-home HVAC and lighting automation.
