  • Sensor accuracy: Look for models with proven sensors (e.g., Swiss Sensirion) and documented accuracy ranges.
  • Forecast and indicators: If you want forecast data and environmental indices (dew point, heat index, mold risk), ensure the model supports those metrics.
  • Power and installation: Consider battery-powered vs. plug-in options and the ease of placing outdoor sensors in appropriate locations.
  • History and alerts: If you need max/min records or alerts for temperature/humidity thresholds, verify these features are included.
