gateway (the frequency is different for various countries because of
regulations).
Note: There’s a built-in heat plate in the 6-in-1 sensor package body, if the lowest
temperature at your place is below -3°C, or 26.6°F, and the weather is
mostly snowy or rainy, then you may need to activate the heater by
supplying an external 5V/1A power to the sensor heating element for
melting accumulated snow or ice, which can influence wind measurement
accuracy significantly. Please contact us at support@ecowitt.com for the
extension cord information if needed.
