Take control of your HVAC zoning with the ESPHome 8-Zone HVAC Controller V2, a purpose-built 24VAC relay board designed for real-world zoning and automation projects.
This V2 version supports all 8 zones, making it a cleaner and more practical solution for controlling duct dampers, valves, and other 24VAC devices without having to cobble together generic relay boards and extra hardware.
Built around the ESP32, this controller is ideal for makers, integrators, and Home Assistant users looking for a smarter way to manage multi-zone HVAC systems.
Whether you are building a custom zoning setup, retrofitting an existing system, or integrating HVAC control into Home Assistant, this board is designed to give you a straightforward and purpose-built platform to work from.

A lot of HVAC and automation projects end up relying on generic relay boards, separate power supplies, and messy wiring arrangements that were never really designed for zoning.
