My own PWS is MID_E7812 and Rachio is reporting that ‘No precipitation data!’. Weather Underground is showing is showing the correct precipitation. If I follow the link to the CWOP Information page everything looks correct. If I then click on the Findu link for the last 24 hours of weather data it also shows the correct amount of precipitation.
Are you using flex daily? If so does the rain data show up in the moisture history chart?
No rain flag on the map comes from the provider and could be faulty, big question is if you actually get the data.
The letter “r” followed by 3 numbers represents the amount of rain in hundredths of inches that fell the past hour. The letter “p” followed by 3 numbers represents the amount of rain in hundredths of inches that fell in the past 24 hours. Only these two precipitation values are accepted by MADIS. The letter “P” followed by 3 numbers represents the amount of rain in hundredths of inches that fell since local midnight.
The raw data (link) being reported to your station omits r and p figures, only reporting the P figure which is not reported to MADIS / NOAA.
“…” designates a missing parameter, as per Q.7 from earlier FAQ.
Basically the software you use to update your CWOP station sucks, sorry, if you send me your Davis device ID / mac address, or a link from their weatherlink map (here), I can start updating your station with the proper rain figures included. You will need to disable the updates from Davis software so that it will not cause interference.
P.S. Seems you are having barometer issues (link) as well , though it could be potentially explained by Davis software:
Looks like rain skip looks at the previous two days for “observed” reading. On the 19th (Sunday), you’ve has 0.13" of rain, which effected the following two days (20th and 21st).
19th itself got skipped because in addition to 0.13" of rain that day, it added 0.02 from two days prior on 17th for the total of 0.15" of observed rainfall.
In summary, when ever evaluation for rain-skip occurs, it totals rain data over the previous two days, if that total is more or equal to threshold for that zone, irrigation is skipped.
