Intelligent HVAC Control for Crestron Home – Engo EFAN Driver by ONIO Interactive

Bring Engo EFAN-series thermostats into your Crestron Home ecosystem with native, two-way control over Modbus RS-485. This driver mirrors Engo’s mobile app capabilities inside Crestron Home, delivering intuitive control, real-time feedback, and powerful automation—without middleware or cloud dependencies.

Key Features

🔹 Full Thermostat Control – Power, heat/cool selection, operation modes (Manual/Schedule/Frost), temperature setpoint, fan level (Off/Low/Mid/High/Auto), ECO toggle and temps, calibration and min/max limits—all from the Crestron Home app.

🔹 Live Status Feedback – Continuous updates for room temperature and humidity, setpoint, operating mode, and online/offline state.

🔹 Multi-Unit Ready – Address devices by Modbus slave ID and deploy up to 20 units per platform instance for room-by-room control.

🔹 Smart Polling & Reliability – Fast startup “priming,” randomized (jittered) polling to reduce bus collisions, quiet windows after writes, and structured diagnostics with clear, per-device log tags (e.g., [ID 3]) for rapid troubleshooting.

🔹 Actions & Events Automation – Use any property as a trigger or action (e.g., automatically raise fan to High above 26 °C), or coordinate HVAC with lighting, shades, occupancy, and more.

🔹 UI-Optimized Design – Tailored pages and clear groupings for everyday use and advanced commissioning.

🔹 No Middleware Required – Direct Modbus RS-485 link between the Crestron processor and the Engo unit. No external servers, scripts, or third-party clouds.

Perfect for installers and power users who want reliable, native-feeling EFAN control with professional-grade diagnostics.
