I have had the IRO up and running for a few weeks and we finally got some precipitation last week so I could validate the PWS’s reporting. What I am seeing is that the PWS I selected is actually VERY accurate, but that accuracy isn’t carrying over to the IRO especially in the precipitation data.
Actually Rachio always shows any precip as 0.08. However I only have a few samples points. Irregardless the numbers never match up. I logged this issue with support but figured I would put it out here for others to look at.
@Hooper, thanks for posting screenshots of your experience. We’ve been communicating via support (and have reported the weather station for review), but I’m curious if anyone else is experiencing this issue?
Apologies for resurrecting an old topic, but I’ve been wondering about this question also. Lots of rain this week here, so I started looking to see if the reporting lined up with my local PWS.
And on Findu for EW7502, it shows:
You have to squint at the graph, but the same daily accumulation (blue line) seems to be the same as what is reported by WU.
I was wondering if it could be some timezone shifting going on, which is annoying but not a big deal, but the numbers don’t quite add up either.
This all came about because of the helpful posts by @johnny2678 and @boldblue737 to get on the PWS bandwagon. But after a little exploration of my currently selected PWS, I noticed the discrepancies above.
Something is up… We had a good bit of rain last Weds. PWS reported 3.97 inches but Rachio only shows 3.94
Note: I’m NOT complaining about my missing 0.03 inches. Just trying to be helpful and point out discrepancies if there is a bug that needs to be squashed.
This is probably not a bug. The moisture level will not go over 120%. Sometimes I’ve seen it at 119% or 121%, but I’m pretty sure that is due to rounding. So the precipitation amount will get lowered in this case to set the moisture level to 120%.
Great observation, and that certainly appears to happen, but it doesn’t totally explain what I was seeing in my post above. In that case, the Iro was actually reporting more precipitation (May 3) than was reported by the weather station.__
@stonecliff, I saw that on yours and it had me totally puzzled as well. I get why it reports less, but I would have thought the only time it reported more would be if you are doing a fill, but that would go to 100% and not 120%. So yours is very odd.
Our team is looking into this. Confirming with NOAA, I can see where our system is picking up the .74: MESOWEST STATION INTERFACE
the 24hour precip is at that level, though the precip since midnight is at .55.
I will connect to our team and see if we are receiving the precip since midnight for this station, as NOAA has not always been redistributing this value. I will update shortly.
So it looks like somehow the daily rate number at midnight (0.19") is being added to the daily total. I would think they should be pulling from the accumulated total only to avoid that confusion.
