📦 Supported Devices

Device	Model	Capabilities
ThirdReality Temp/Humidity Sensor	3RHT18BZ (assumed)	Temperature, Humidity, Battery, Dew Point

🧊 Note: Dew point is calculated only for devices that report both temperature and humidity.

🌡️ Dew Point Calculation

For compatible environmental sensors (e.g., 3RHT18BZ), this driver adds support for dew point as a calculated attribute.

• Formula used: Magnus approximation (accurate for indoor climate ranges)
• Attribute exposed: dewPoint (°C or °F based on Hubitat location settings)
• Enables smarter rules and dashboards for:
  • Humidity control
  • Mold risk reduction
  • HVAC optimization
