jmed999 Posted July 16, 2014 Share Posted July 16, 2014 My weather module claims I've had 0.24 in of rain today. In reality I've had 0.01 in rain today and 0.23 in of rain yesterday. How can I fix this? Thanks! Btw, you can see my rain totals for yesterday and today here... http://www.wunderground.com/personal-weather-station/dashboard?ID=KSCAIKEN13#history Link to comment

Xathros Posted July 16, 2014 Share Posted July 16, 2014 Looks to me like you are seeing rain in the past 24hrs rather than what WB called Rain Today. -Xathros Link to comment
jmed999 Posted July 16, 2014 Author Share Posted July 16, 2014 Sure it's, E1583/EW1583. I forget the letters I added to make it work since its aPWS. I'm not at home to check but whatever the 3 letters are just add them and that's my PWS ID. Thanks! Link to comment
jmed999 Posted July 16, 2014 Author Share Posted July 16, 2014 The 1st 3 letters of my station is "mid". It still says 0.24 in of rain. It should say 0.01 in. It's adding yesterday's rain for some reason. Thanks! Link to comment
PurdueGuy Posted July 16, 2014 Share Posted July 16, 2014 The station I use is a personal station nearby. ISY shows: Condition: Rain Cloud Condition: Partly Cloudy Rain today: 0 inches Condition Tomorrow: Drizzle Rain Tomorrow: 0 inches Being in SoCal, I could only wish we were getting rain! How is the condition calculated? Do I just happen to have the lucky variables that the outcome shows as rain? If I switch to "KLGB" I no longer get "Condition" so I can't see what it would be. Switching back to the original station, and now I don't get the "Condition" or "Condition Tomorrow" fields. Now I'm confused. Link to comment

Thanks! It seems my Total Rain Today value is also the sum of yesterday's and today's values. My ISY is showing Total Rain Today = 1.62 inches. My PWS reported 1.57" yesterday and 0.05" today.

IndyMike Posted July 16, 2014 Share Posted July 16, 2014 I've been seeing similar things with my local airport station (official WBS/NOAA station). Seem's to be linked to the HAM "rain in the past 6 hours" which can roll into the next day. The following is a comparison of Weather Underground reports VS HAM (ISY). The second and third tables are HAM reports from 7-14 and 7-15. The discrepancy between Weatherunderground and HAM seems to be due to a HAM rollover of 0.46" from the previous day. No explanation for the discrepancy on 7-14 Link to comment
jmed999 Posted July 17, 2014 Author Share Posted July 17, 2014 I noticed this morning that my irrigation system didn't run because it thought I got 0.24 in of rain yesterday which isn't true. I'll have to go back to manual watering for now. Link to comment
Michel Kohanim Posted July 17, 2014 Share Posted July 17, 2014 Hello all, I am so very sorry for the trouble. I have submitted a ticket to HAM (thanks to jmed999) and awaiting a response. I'll let you know as soon as I hear back. With kind regards, Michel Link to comment
Michel Kohanim Posted July 18, 2014 Share Posted July 18, 2014 Hi jmed999, I still haven't heard back from HAM ... I will follow up. With kind regards, MIchel Link to comment

MWareman Posted July 18, 2014 Share Posted July 18, 2014 The irrigation module really needs the ability to talk to a very local rain sensor to calculate ET. Even a half mile makes a massive difference! I'm having a new house built, and I'm currently living in a apartment less that a mile away. I had a cheap rain sensor at each location, same brand, for the last couple of weeks. One registers .78" and the other registers .09" over the same week. This is wildly different than what ISY is reporting for my closest station. I really, really, really want to be able to feed local information in, without having to poll a web service at all. Please make this possible in 5.x.. Link to comment
jmed999 Posted July 18, 2014 Author Share Posted July 18, 2014 Be careful.....a rain sensor will not help you calculate ET. ET comes from other data from the weather station. A rain sensor will however give you "Total Rain Today" which subtracted from the ET will give you "Yesterdays Water Deficit". That continues to add up as "Irrigation Requirement". I would like to get data from my personal weather station directly to the ISY. That's different from rain gauge only data. Link to comment
MWareman Posted July 19, 2014 Share Posted July 19, 2014 True enough. I was really only addressing my experience with 'Rain Today' - but the need to feed full climate data from a local PWS into the ISY irrigation module is acute - if we want even close needed water calculations. I *really* hope this happens with 5.x. Data from more than a few 10s of yards away can really make a difference! Link to comment
jmed999 Posted July 19, 2014 Author Share Posted July 19, 2014 I couldn't agree more! Link to comment
jmed999 Posted July 21, 2014 Author Share Posted July 21, 2014 My rain today on the ISY is 0.28" but according to my PWS I got 0.27" today and 0.02" yesterday. So it's still wrong but not quiet sure if it's adding today and yesterday like it was before or not. Link to comment
wrj0 Posted July 21, 2014 Share Posted July 21, 2014 Sure seems like it's adding Rain Today and Rain Yesterday. My ISY shows Rain Today = 0.6" while my PWS reported 0.4" Yesterday and 0.2" Today. Link to comment
Michel Kohanim Posted July 21, 2014 Share Posted July 21, 2014 Hello everyone, here's an update from HAM Support: Thanks. As you know the core issue is the data from NOAA for these stations only includes the 1 hour precip and 24 hour precip. Some stations report 24 hour precip from midnight & others report a running last 24 hours. The stations doing the latter are the ones you are having a problem with. I have been told that our team is working on some scripts that can run nightly to determine these stations. Then the system can subtract the value last reported right around midnight local time. This should solve the majority of the issues, though may not be 100% accurate, but should be fairly close. I will continue to provide updates as the team works on this. With kind regards, Michel Link to comment
jmed999 Posted July 21, 2014 Author Share Posted July 21, 2014 I can tell you for sure my station reports today's rain from midnight and not the last 24 hours so I don't think their solution will fix my problem. At this point I can't use the irrigation module and I think they are the wrong path. I hope I'm wrong! Thanks for the hard work and trying to get this resolved Michel. Link to comment
Michel Kohanim Posted July 21, 2014 Share Posted July 21, 2014 Hi jmed999, Thanks so very much for letting me know. I forwarded your message to HAM. With kind regards,Michel Link to comment
jmed999 Posted July 22, 2014 Author Share Posted July 22, 2014 My rain today still says 0.28". So if it was reporting the last 24 hours it would have changed since it rained on and off about all day yesterday. If my rain today was a "running last 24 hours" as HAM says it would have changed from early this morning. Also, it has rained a good bit today. With that said, if it were a "running last 24 hours" it would have changed from this morning. Link to comment
jmed999 Posted July 22, 2014 Author Share Posted July 22, 2014 Just for fun....I've had 0.42" of rain today. http://www.wunderground.com/personal-weather-station/dashboard?ID=KSCAIKEN13#history So again if I was getting a running 24 hours it would mathematically be impossible to only show 0.28" so far today.
