Dutch residence automation specialist DomeCtrl is making ready to launch an all-in-one management system to deliver your radiant underfloor heating system below Dwelling Assistant’s purview: the ControlBox.
“ControlBox is what it is advisable management hydronic radiant flooring heating [RFH] methods with Dwelling Assistant,” DomeCtr’s Anton Verburg writes of the system. “It’s designed to manage thermal valves, hydraulic PWM [Pulse-Width Modulation] pumps, and associated RFH gadgets. It may possibly learn giant numbers of 1-wire temperature sensors over lengthy cables (>6m). ControlBox additionally accommodates 32 LED-strip output channels, offering as much as 2kW output.”

Contained in the chunky ControlBox housing is a Raspberry Pi 5 4GB with a Non-Risky Reminiscence Specific (NVMe) solid-state drive (SSD) for storage — permitting it to behave as a Dwelling Assistant server itself, relatively than as a consumer system. For these with present Dwelling Assistant installations, DomeCtrl guarantees a variant that makes use of an Espressif ESP32-powered WT32-ETH01 operating the ESPHome firmware.
The management system takes mains voltage and supplies 4 1.5A mains-level outputs, 16 24VAC 500mA outputs for valves and different peripherals, three opto-isolated general-purpose enter/output (GPIO) pins plus two with pulse-width modulation (PWM) capabilities, all of which help as much as 24VDC and could be pulled as much as 5V or 12V, 32 PWM outputs devoted to LED lighting strips with 10A present per connector, two 1-Wire line driver channels, a half-duplex RS485 bus, and 433MHz transmitter and receiver modules for wi-fi communication.
The corporate is planning to launch a crowdfunding marketing campaign for the ControlBox within the close to future, with events invited to join notifications on Crowd Provide, and guarantees that the schematics will probably be revealed to GitHub below an as-yet unspecified license — together with Dwelling Assistant configurations.
