For grass areas
Vegetation Type - Warm Season Grass
Spray head - Generic rotary nozzle I have the Hunter MP Rotators
Soil Type - Sandy Loam
Exposure - Lots of Sun - your may vary on zone
Slope - Slight
My advanced settings for grass areas are:
Available Water 0.12in/in (default based on soil type)
Root depth 6 in (default was 9 but St Augustine should be in the 4 - 6 range)
Allowed Depletion 50%
Efficiency 70%
Crop Coefficient - click on the lock, then check All Zones. This changes from Static to Dynamic. Crop Coefficients actually change month to month due to the weather.
For Flower beds
Vegetation Type - Shrubs
Spray Head - Mister - I have the little red fan sprays
Soil Type - Loam - landscapers amended the soil
Exposure - Lots of sun
Slope - Flat
Advanced Settings
Available Water 0.17in/in (default based on soil type)
Root depth 15 in (default for shrubs)
Allowed Depletion 50%
Efficiency 95%
Crop Coefficient - should be Dynamic if you set all zones to Dynamic above
I've added a 2" Vu-Flow filter to the irrigation water since we are using pond water in the south for irrigation and it plugs the filters in the sprinkler heads. This filter requires cleaning once or twice a month but sure beats cleaning the filters in each head.
Secondly, I added the Everydrop flowmeter to the system. This allows you to get actual gpm usage on each zone. With that, you can physically measure the area of each zone and then calculate the precipitation rate (value you'd enter for Nozzle Inches Per Hour) instead of using the default sprinkler head values. Let's assume you have the MP rotators. They spec at 0.4 inches/hour. However, your system should have head to head coverage (i.e. water from one head reaches the other head). So technically for a given area you are putting down more than 0.4 inches per hour. I'm sure I have greater than the 70% efficiency I put in my advanced settings but I wanted the system to run a little longer.
Added benefits of the flowmeter is that you'll get notifications of low flow, high flow and any flow after zones shut off. Low flow just sends a notification. High flow (break in line or a sprinkler head is damaged) sends a notification AND turns off the zone. You'll need to fix the issue and re-enable the zone before that zone runs in any future schedules.
You can do your own soil test using a jar. Remove some grass (leave any dirt) in a 3 or 4 inch circle. Dig out soil about 6 inches deep. Collect this soil to put it in the jar. How to measure is here:
Jar Test
Then download the first Excel sheet here:
Soil Texture Triangle
My values were:
Sand 68%
Clay 21%
Silt 11%
Based on the triangle, I'm barely in the sandy clay loam section. That isn't an option in Rachio so I dropped down to the Sandy loam. Rachio will think the soil is capable of holding less water which is fine.
I actually measured each zone area and put those values in the advanced settings. Then I followed this article to calculate precipitation rate -
Calculating Precipitation Rate. And then changed my nozzle inches per hour to this value.
I did make the in app purchase for Valve Monitoring. This will notify you if a valve uses more or less current than when initially calibrated. It can help in seeing when a valve needs to be replaced. Of course, once purchased you'll have to go into the valve monitoring advanced settings and turn that feature on. Mine are set +/- 25%.
I also have my own weather station connected to Weather Underground so Rachio gets the actual temps and rain values from my station. Do you have a station close by that you are using or are you letting Rachio calculate rainfall?
While it may seem I have a good handle on the system, I'm still learning and tweaking.
