The service requires an Internet connection, an account in Level2 and a subscription to the weather forecast. The function is available since version 2.5.2400.

If for some reason the data has not been received, the value nil will be returned.

The interval is a three-hour time interval in the future. From zero to 6. Total six intervals. Zero interval is the forecast in about 3 hours. The first interval is the forecast in six hours. Etc. The format of the returned data is identical to the function GetCurrentWeather.

function main (userId)
    local current = GetCurrentWeather();
    local nextForecast = GetForecastWeather(0);
 
    if (nextForecast.temperature > 6 and current.temperature > 6) then -- positive temperature
        WriteReg(91, 0); -- turn anti-ice off 
    end
 
    if (current.snow < 1 and nextForecast.snow < 1) then -- not snowing 
        WriteReg(91, 0); -- turn anti-ice off
    end
 
    if (current.cloudness < 20 and nextForecast.cloudness < 20) then -- clear
        WriteReg(91, 0); -- turn anti-ice
    end
 
    if (current.snow > 2 or nextForecast.snow > 2) then -- it's snowing
        WriteReg(91, 1); -- turn anti-ice on
    end
