How can we help?


Weather Underground public station actual rainfall data --- Did we really need the API?

    Also, the log of my HD-16, I see the following request going to wunderground;

    https://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID= KKYCREST23&day=16&month=6&year=2019&graphspan=week&format=0&units=metric

    Which show the following error: error: HTTP Error 400: Bad Request


    However when I enter that same url directly into a browser, I get the following which clearly show observed data for the past 3 days;

    Date,TemperatureHighC,TemperatureAvgC,TemperatureLowC,DewpointHighC,DewpointAvgC,DewpointLowC,HumidityHigh,HumidityAvg,HumidityLow,PressureMaxhPa,PressureMinhPa,WindSpeedMaxKMH,WindSpeedAvgKMH,GustSpeedMaxKMH,PrecipitationSumCM
    2019-6-16,28.6,24.0,19.4,20.0,14.6,6.1,89,63,29,1007,1002,20,1,28,3.76
    2019-6-17,28.0,24.3,20.6,20.9,18.0,13.6,96,75,43,1008,1004,13,0,20,1.35
    2019-6-18,22.3,21.9,21.6,20.2,19.9,19.7,89,88,88,1007,1006,6,0,8,0.53

    Probably worth noting that the "KKYCREST2" weather station is not mine. It's just one nearby.

    Maybe the Rainmachine is trying to do what I'm envisioning, but there is a bug or something such that its not getting any data back? Maybe something only the developers can explain? I'll have to look at the logs on my unit when I'm home to see if it has a similar message.

    I'm not sure if this is the correct way to ask, but can we get an official response from the support team at RainMachine as to why the observed data seems to be available from WUnderground but it is not working on our RainMachines? Is the only way that I can fix this is by spending a bunch of money on a Weather Station?

    Users need some way of getting observed weather data into their RainMachine device so that the proper calculations are made. After all, that is why we all bought the device. The NOAA forecasting is just not accurate enough. For instance, the other day NOAA forecasted 1.5" of rain for my area... it didn't rain 1 drop.

    RainMachine... Please Help!!

    The WUnderground service uses the same url that you find out when not configured with a API Key.  It still works on our internal test machines although it's not very reliable. It does seem to get errors from time to time, probably related to WUnderground servers. 

    You can try to REFRESH the weather services by hand and/or select another station to check if you can get data.

    We are also working on getting this observed data from NOAA (which has a good part of stations that WUnderground has) and integrate this in the NOAA weather service.

    That is important into to know, I removed the old API key and saw the same entry as RDLinKY, I added a few options for stations around me, and it seems to be pulling data from one station more consistently. For some reason the station closest to me never returns data even though it all appears there when loading the page in a browser, but the second closest station returns rainfall data so its better than nothing.

    I had also found some beta wu parser code on here but it seems to work the same way as the officially integrated code, from what I can tell at least.

    Keep up the good work, if you want any specifics or more details let me know.

    Thanks
