    Just noticed it is showing .01in rain(same as wunderground) on the monthly chart for yesterday, but still shows 0in on the weekly chart.  So I guess everything is working as it should, just a glitch with the weekly chart not updating correctly?

    Did actually find your answer? I just supported a ticket because I was having my sprinkler program kick on in the middle of it raining while connected to a weather station properly reporting rain accumulation near me. When I went to see the history from Rainmachine and compare it to the wunderground data, I was seeing a discrepancy. I still have an issue with this. Support acknowledged the ticket, asked for my log and hasn't responded despite multiple attempts to get an update.

    For me, rainfall wasn't showing up because I was looking at the weekly chart.  The weekly just shows the forecast/expected rain, the monthly chart shows measured rain. 

    If you want a program to shut off during rain, I believe you need a rain sensor.  I haven't really looked into it yet , but I think the RainMachine only uses measured rain to calculate upcoming programs run times.  Maybe Someone from RainMachine will respond here and help you out more, not sure how active they are on their forum though.

    Not working out for me.  Where I live, rain will be in the forecast every day, but it often doesn't rain on my lawn for a week.  I can get pretty accurate rain fall data from Wunderground at the airport near my house, but there is a big difference between what is forecast and the rain that actually falls.  My lawn is parched but rainmachine keeps cutting back on watering thinking tomorrow it will rain.  

    Documentation is insufficient to gain sufficient insight into how the program operates to use it to best effect.  I've just deleted seasonal adjustments to use forecast data only.  I've changed rain sensitivity to 50% thinking the forecast is maybe 50% accurate.  I've got soil type set as sand and used watering time to 30 min per zone with a 200% over-watering setting.  I'm thinking about turning on rain restrictions guessing it may make assumptions based on actual rain fall instead of the forecast, but it's trial and error because who knows where the program takes it data from.

    Being able to see on a graph how much water the lawn actually gets (rain + sprinkler) would be a big help.  I see this on the monthly chart but with insufficient granularity to facilitate decision making. It would be interesting to see on a graph of forecast vs actual rain fall.  But forecast rain that doesn't fall handicaps the program.  There needs to be a way to track, calculate the decrepency account for deminished watering based on the inaccurate forecast and catch up the irrigation time.  It be really good to store this as an "inaccuracy index" seasonaly adjust it and apply it to the programs future calculations of sprinkler time adjustments.

    Yep, future is unpredictable ;-)
    BTW, RM can be used different ways, starting from fixed time counter, counter with ET history correction used, QPF forecasted counter, up to QPF forecasted counter with back rain checking (PA using PWS). I don't think you tried all :-)
    More serious about graphs - something like that can be? Water used by RM is shown as rain equivalent.

    Thank you for trying to help.  
     
    Take a look at Wunderground for Jun 30th.  KPMP, the station I selected on the Wunderground web page shows rain fall of 0.27 inch, but Rain Machine displays no rain fall.  My programing rules say suspend watering with 0.25 inch or greater rain fall.  Watering started on 6/30 at 00:01 and is applying what looks to be 89% 
     
    Remembering I set rain sensitivity at 50%, Is that correct?  Because soil is sand and temps near 90, that rain fall doesn’t have much impact on the watering program that started about 12 hours latter.  It subtracts just 11%.  If I set rain sensitivity to 100% would it have subtracted 22%?   I might tend to think it did not apply the rain fall in it’s calculation, because the rain doesn’t display on the RM web page for rain observed weather history.  But I just don't know the formula the program uses to check.
     
     I bought a Rain Bird Soil Moisture sensor today and will install it next week to address what I'm guessing is the programs not showing or accounting for rain fall.  Am I missing something?
     
    The graphs are nice.  I don’t think I’ve yet read anything about how to configure the counter different ways as you mentioned.  Could you point me to that documentation?
     
    On the graph, I guess to see actual rain amount you have to look at 30 days of data.  One day this month there was 3.4 inches of rain.  Once the graph adjusts it’s scale to show 3.4 inches, any amount less that 0.5 inch gets shrunk on the graph to the point you can’t discern it’s amount.  (More than 86 mm as you set up your graph)

    Hi Alto,
    1. Can you be so kind, open RM in browser, select Month graph, cut it and present here ? We all will know what your RM thinks about weather in June (QPF, PA).
    Yep, it can be nice, if we can see RM month watering (presented with PA) similar way, this way visible garden water balance is complete.

    2.Rather not, rain sesnsitivity only correct times countings, 50% means take less rain in account. But if QPF is wrong, it means nothing.

    3.Moisture sensor is good idea to not kill plants at all.

    4.It's easy, just go to Zones, open one, and read about Weather & Seasonal Adjustments.
    If you uncheck both, RM will be fixed time counter, if you turn on Seasonal Adjustments only RM will use historical ET corrections, if you select Use Weather Data only RM will use current weather for countings, and finally when you check both they will be used both :-)
    Just in device docs.

    5.I agree, but weather sometimes give us 10 times more water in rain (my sample pict up for June 28). Just life :-)

    Hi, Thanks again for your continued interest.

    Today, after logging out of the browser RM interface, the rain from 6/30 is displayed.  It was not displayed last night in the system while the sprinkler was running.  Is there a significant time lag for this information to be used in the RM run time calculation?

     

    Note that in the QPF (Wunderground Forecast Rain) we see an interesting anomaly.  On days between the points when Wunderground predicts rain, the graph connects the points.  There is no Wunderground data points for these days, but reading the graph suggests there is.  Is this just an artifact on the graph, or is the program factoring in QPF that is not really there?

    If I understand your statement (2.) above correctly, You are telling me the Rain Sensitivity is applied to Forecast Rain Fall only (QPF) and not Actual Rain Fall.

    (3)  My understanding of the Moisture sensor is that it will function in the same fashion as a rain sensor, in that it over-rides the sprinkler commands to turn off watering.  It would be useful to me to use it could work in reverse, or to over-ride the RM controller's attenuation of sprinkler run time?

    (4) Thank you.  I had discerned these effects in my experience.  I initially had selected both, and saw additional QPF plots predicting rainfall daily, when the current Wunderground forecast did not.  I turned off Seasonal adjustment.  It was just feeding the RM sprinkler calculation bad data.  I am now using "Use Weather Data Only".

    (5) You might consider using a logarithmically progressing scale for the rain graph.  This would compress display of large rainfall while preserving the ability to discern clearly small amounts of rain when you want to clearly see if enough rain had fallen.

    1.No, it's normal. Precipitation accumulated previous day by station is used for next day watering corrections in RM.
    Sometimes users can be confused, why current day station PA wasn't too. Long story.
    2.I'm rather using RM main page Month graph for it, to compare both QPF used & station measured/observed rain.
    Just less works than compare two graphs, means Rain QPF vs Rain in Weather section ;-)
    Returning to your case - you can check how WU data was collected by RM exactly (every 6 hours) in Settings, About, View log, but it is rather for sophisticated users.
    3.Depends on device type, there are a lot of different ones. But it is hard to find moisture wireless sensor, cheap&easy to integrate with RM now.
    Maybe Whispear this year?
    4.In contrast I'm using both, up to this time it works. Not that my net connection is bad, isn't :-)
    5.Yep, it can be solved many ways, ie rain water lost in such cases can be cut off on reasonable level, etc.

    Now cutting back weather sensitivity to 25%.  The grass is turning brown and RM delivered only about 30% of Programed watering.  I've got rain catch cups all over the yard to verify sprinkler coverage.

    just about to convert RM to dumb timer mode.  Forecast adjustment is worthless were I live.  Maybe if you live where most weather is associated with a front, prediction could be useful, but not here.  It would be better for my lawn if it just looked at rain history.  Too bad there is not a setting to allow the user to set threshold for rain predictions.  I.e. Let me ignore forecast for 40% probability of rain and accept forecast if it says 80% rain chance.

    the controller does not learn and adapt future watering from sensors connected to it.  It just takes garbage internet data in and spits garbage adjustments out.  I don't see much evidence of any AI here.

    It looks like July 4th doesn't show up in the program's rain history.  This day just omitted.  What's up with that.  Rain in forecast and in history not the same as Wunderground reports at my selected weather station.  RM showing more rain than Wunderground, although it's less then 0.1 inch over.

    RM is continuously over estimating the rain fall my lawn will receive.  I've added more sprinkler heads and cranked up time per zone up to 45 min. So when RM cuts back watering I will hopefuly still get 0.25 inch water on the lawn.

     

    I've got a rain bird soil moisture sensor SMRT -Y that I want to connect to the rain sensor port, but I'm unsure which wires to use.  Anyone install one of these using the optional RM plug?  What wires did you use?

    I spent about 30 min on phone where I gave the RM tech access to my system to tweak my settings.  Now the system is much worse.  Last night the system cut my 45 min zone time down to 5 min.  I've had no rain in 5 days, sprinkler ran 5 min in last 4 days.  The news says flooding today, but the sky is blue over my house now, and maybe it will rain on my lawn oh maybe not, 50 to 70% chance of rain.  That's what it's been for days.

     

    i returned the rain bird soil moisture detector, no one at rain bird or rm could tell me how to connect it use internet the rm rain sensor ports.  Waiting  on delivery of a toro soil moisture sensor and turning off forecast, its killing my landscaping.  Probably Ned to add a rain sensor too.

    Yesterday it rained over 1 inch.  Tonight the sprinkler began a nearly full 45 min per zone cycle.  RM shows 0 inches of rain fall from Wunderground, and zero inches of forecast rain fall.

     

    as for the forecast, I guess that is because I set rain sensitivity to 10%, and RM adjusted down the actual Wunderground forecast 90% and it rounded out to zero.  Is that assumption correct?

     

    For the actual rainfall, it started raining at 12:35 and the sprinkler started at 24:00.  So I assume RM doesn't show the rain because the weather parsers up date at 6 hour increments and the cycle started a little less then 6 hours after the rain started.  Is that guess correct?

     

    I'm waiting on delivery of a Toro wireless soil moisture sensor and rain sensor and will install when they arrive. I hope that will help get the results I'm seeking.

    I was excited to discovery the RM functionality to write my own weather parser..

    i gave it a shot and edited an existing parser for Wunderground with my own modifications.  It tested ok, but when I tried to upload the .PY file rM gave me an error message and failed to upload the file.  Is this developer functionality working?  Why would the wed interface fail to upload any file with a .py extension?

    Ok, got my edited weather parser uploaded by using the Rest API.  It's working.  

     

    Tried to SSH into rain machine but failed.  Was useing an iMac and got a permission denied message.  I'm thinking it's because I created the SSH key on an encryptied hard drive, but I don't know.  I will probably try again from a pc using Putty.

     

    am I right in thinking that useing SSH I can edit all the rain machine's programming?

    Alright, got in via SSH from the MAC.  More than 2,000 pages of files in this little box. A lot just Android files and Phython files.

     

    how bad can I mess things up before it becomes in-recoverable?

    Also the Toro wireless rain sensor and soil moisture sensor have arrived in been connected via the auxiliary rain sensor port.   I got a push notification last night that the rain sensor was triggered in shut off the sprinkling Cycle. Unfortunately because both the rain sensor in soil moisture sensor are connected in series via the same connection at the range sensor port It's not possible to do soon whether the event was triggered by the rain sensor or the soil moisture sensor.

     It has been surprising to know how quickly the soil moisture level decreases once the sun is up.  The data from this tool suggest that the drainage is so rapid that my yard would benefit from every 12 hour watering.

    The soil moisture sensor reports a temperature of 136°F. I question the accuracy of this and went outside and touched it and it is hot.  Outdoor temperature is 90°F.  The sun is intense, today is partly cloudy.
