EGI HVAC Adapter Solo
Smart Control for a Single Indoor Unit (ZigBee Tuya or Modbus RTU)
Connect a single indoor air conditioning unit to your smart home or building automation system. Factory-configured by brand, this compact adapter enables full control via Tuya ZigBee or Modbus RTU (RS-485) — no software setup required.
Overview
The EGI HVAC Adapter Solo is a purpose-built integration adapter that allows a single indoor unit (IDU) from your VRF or ducted HVAC system to be connected to your Tuya Smart Home ecosystem via ZigBee or to a Modbus RTU-based Building Management System (BMS).
Designed for professional installers, each adapter is factory-programmed for a specific air conditioner brand — ready for plug-and-play operation with no configuration required on-site.
Why Choose the ZigBee Version?
The ZigBee variant of this adapter is designed for seamless connectivity to:
Tuya Smart App
Smart Life App
ZigBee 3.0 Home Hubs and Gateways
Home Assistant (via Tuya integration)
Once installed and paired with your ZigBee hub, the indoor unit becomes controllable via app or smart home platform — enabling scheduling, voice control (via Tuya integrations), remote monitoring, and full climate automation.
This makes the ZigBee model the preferred choice for residential and light commercial smart home deployments, especially where app-based control and wireless infrastructure are preferred over RS-485 wiring.
