paulbates Posted September 10, 2014 Posted September 10, 2014 (edited) I am working on programming my sprinklers with the ISY. One of my longer term challenges is getting local rain amount "just right". Having tried Weatherbug and WeatherUnderground, I get ok results, but not the results I am looking for. I just put into the hydreon sensor, and today's day long rain here in MI proves that it is working consistently and accurately once calibrated. My question is, can I calculate a rain value (whatever units are needed) as an input to the Irrigation module? Edited September 10, 2014 by paulbates
Michel Kohanim Posted September 12, 2014 Posted September 12, 2014 Hi paulbates, Not currently but this is certainly something we have to work on since it seems that there are a lot of reliability issues with weather stations. #152 Medium. With kind regards, Michel
paulbates Posted September 12, 2014 Author Posted September 12, 2014 (edited) Thanks Michel Wednesday was the poster child for this WX station struggle: In calibrating my new hydreon sensor yesterday, I logged and compared its readings to 6 local WeatherBug and WeatherUnderground stations. As it rained all day, it was a great sample. My mistake was thinking i could calibrate against other 'net weather stations. They were all within 5 miles of me, 4 within 2 miles. The total for the day spanned from 0.5" to 2.2" across those 6 WU/WB stations !!?? This rainstorm was massive and spanned my half of MI, there is not good explanation for that much variance. I'm going to calibrate against a plastic gauge. These 'net weather challenges are not new or unique to HA or UD alone. I would happily take heat, wind and other readings from Climate module, they have been close enough in WB over time. Paul Sent from my iPad using Tapatalk HD Edited September 12, 2014 by paulbates
Michel Kohanim Posted September 12, 2014 Posted September 12, 2014 Hi Paul, Thanks so very much for the update. This is precisely what HAM is grappling with as well. Hopefully their new algorithm is going to make things a little more accurate. With kind regards, Michel
hart2hart Posted September 22, 2014 Posted September 22, 2014 Count me as +1 on ability to get rainfall from local device.
