⚡ ControlBox: Home Assistant on Raspberry Pi 5

DomeCtrl’s ControlBox is a Raspberry Pi 5-based controller running Home Assistant, primarily designed for hydronic radiant floor heating systems. The device targets residential automation, supporting lighting solutions and integration with energy devices such as solar collectors, photovoltaic installations, heat pumps, and hydraulic pumps. It manages thermal valves and PWM pumps while reading multiple 1-wire temperature sensors over cables longer than 6 meters.

The main board features a Raspberry Pi 5 SBC with 4GB RAM and a 128GB NVMe SSD pre-loaded with Home Assistant. Wired communication includes Gigabit Ethernet on the SBC and a half-duplex RS485 communication bus operating at 5 V. Wireless connectivity relies on WiFi 5 and Bluetooth 5 native to the SBC, supplemented by a W32-ESP01 header for control via ESPHome.

Additional wireless capabilities include 433 MHz transmitter and receiver modules for communication with peripherals like ClickOnClickOff devices, curtain rails, screens, and garage doors. The system provides 32 LED-strip output channels capable of up to 2 kW output. Input and output connections are handled via terminal blocks, facilitating direct integration with various home automation components.
