@g-man Did something happen to the 2nd sheet you had with WU integration? I'm only seeing the simple sheet attached now.

@srmorris2 I think there is an issue with forum settings not showing this correctly. I'm not currently at home, so I will check it later.

Also, give me a few days. I re did the log to use Darksky API instead of weather underground. Weather underground shut down it's API keys as part of IBM and the weather channel taking over. I'm still testing the new functions (alpha release). I've been on family vacation and not at home.

I did an update to the Log. Read the top post for the new features using DarkSky instead of Weather Underground

I know a few members were waiting on this. @Pete1313 @ksturfguy @TonyC

The Climate tab has me drooling. I have two soil test envelopes sitting on my counter, the Soil Deficit tab has me wanting to send one to the lab.

I'm intrigued by the Alexa integration, do share more. I too am a Smart Home (OpenHAB) Junkie, and would rip every switch out of my house if I could. Maybe a reminder driven off of these calculations for applications and other Tasks. I also have a To Do tab I'm using, might need to get that bad boy popping up on my mobile using MQTT or Google reminders. There are so many possibilities here.

Thanks for sharing.

Great stuff!

Bug report:

Yesterday Indy had more than in inch of rain (yes in January). When I looked at my log, I noticed no precipitation data was reported. The value was reported for previous days.

Upon investigation, the API call: precipAccumulation = The amount of snowfall accumulation, in inches. (If no snowfall, this property will not be defined.) Very useful, right? They dont seem to have an object for just rain. I will email them to see if there is a work around.

I discovered this the hard way too. I could not find a total rainfall amount being reported anywhere. Please do share what they reply with.

I got a response back:
Rain data is provided under the `precipIntensity` field. This value provides the rate of hourly rainfall. So you may either add up the 24 hourly values in the `hourly` block, or multiply the value in the `daily` block by 24.
I need to try it.

I'm testing it here too.

I just removed all the Weather Underground stuff. They finally shut down the API. DarkSky works but it is not as accurate for rain data.

This is awesome! I had my own spreadsheet and logged some of my activities recently, but it's very basic. I'm certainly interested in something more advanced like this.

Thank you

I was able to change the units from Standard (Celsius) to Imperial (Fahrenheit) units by changing the units=si to units=us within the following variable (defined twice):

Code: Select all

var url = "https://api.darksky.net/forecast/" + api + "/" + lat + "," + long + "," + ts + "?units=si&exclude=currently,minutely,hourly,alerts" ;
However, it definitely seems to be breaking several calculations. It's going to take me some time to narrow down on where these are located. You wouldn't be able to point me in the right direction?

Most of the formulas/threadsholds are developed in metric system by Univ research. That's why I kept everything in metric. I did create a sheet called NotMetric to convert. The graphs use imperial.

I've been tinkering with this log sheet...very impressive. Thank you for sharing, looks like it was a good amount of work!

I am entering some soil test results...may I ask what MLSN is and how to determine that number?

Ridgerunner's Soil Test Thread explains. I didn't really get it until I read Turf Hacker's MLSN MATH Step by Step

Is the prodiamine calculator set up for half-rate? When I put in my square footage (1,574 sq ft), I am getting .376 ounces of prodiamine.

In cell F5 you enter your desired rate. This is not the ai lb/acre rate but the product rate. For example, if you enter 0.5 lb/acre rate, that means 0.325lb ai/acre rate (0.5 * 65%) for the 65WSG.

FYI, 0.5lb/acre rate is what I use for split spring rate. I prefer to deal with grams for this, so I use 5g/ksqft for split rate.

This sheet has room for improvement.

@llO0DQLE this log will help you calculate the GP. For a cool season lawn the ideal temperature is 68F. GP is a formula correlates grass growing to temperature.
