We do not recommend rechargeable batteries. They have lower voltages, they do not operate well at wide temperature ranges, and do not last as long, resulting in poorer reception.

To achieve proper alignment, it is helpful to use a compass (many cell phones have a compass application). Once rotated in the correct orientation, lightly tighten the bolts a little more (use a wrench) to prevent further rotation.

    experience intermittent communication between sensor and console, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or receivers to avoid the interference and establish reliable communication. The frequencies used by the sensors are one of (depending on your location): 433, 868, or 915 MHz (915 MHz for United States).

    Figure 18 6.4.3 Relative Pressure Calibration Discussion The calibration was set on ecowitt app. To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure.

  • Page 33: Weather Forecasting

    6.14 Weather Forecasting The five weather icons are Sunny, Partly Cloudy, Cloudy, Rainy, Stormy and Snowy. The forecast icon is based on the rate of change of barometric pressure. Please allow at least one month for the weather station to learn the barometric pressure over time.

  • Page 34: Specification

    The reason the current conditions do not match the forecast icon is because the forecast is a prediction 24-48 hours in advance. In most locations, this prediction is only 70% accurate and it is a good idea to consult the National Weather Service for more accurate weather forecasts.
