Any news about the Zimmerman method to take more days into account I posted on 5 nov 2015?

thanks

Any update about this feature request?

I am interested.

I live in Belgium, so I am thinking about °C and l/m but the idea looks good to be able to tweak a bit the Zimmerman method.

[Wokkeltje]

any news about a release date for this new feature?

tnx in advance

[Wokkeltje]

tnx, found a way using the API to start my gardenlights.

1 important thing I found: most online MD5 hash convertors to convert the password gave me uppercases instead of the needed lower cases.

[Wokkeltje]

I like the idea to be able to start a program using an API call.

Why I would use it.

I want to control my garden lights using OS, this will also be the light on the driveway and front door (this program will run from sunset till 11pm with my other feature request 🙂 ).
Now it would be nice to be able to use a shortcut on my phone to be able to manually start (in case I return home very late and the garden lights are already put out) that program for let say 15 minutes without needing to open the complete OS app, select the program and start it.

tnx

Any idea if this feature request is still on the list? And in what timeframe?

Tnx

I’m from Staden.

I have a pump and 1 valve controlled by the OpenSprinkler.
The OS sprinkler is bought from http://www.opensprinkler.com and the raspberry Pi from https://www.sossolutions.be/
Most of the rainbird material comes from https://www.leidingshop.nl/

Currently everything is disconnected because of the winter.

[Wokkeltje]

A reason for the PI model is that you can order the Pi in Europe so you don’t pay import taxes on this part.
The OS is a cheaper that way and has import taxes since it comes from the US.

I power the OS using the trafo of my doorbell (currently without issues)

[Wokkeltje]

I have the OpenSprinkler Pi (Plus) with a Raspberry PI B+
I use it to water my plants in the garden using (currently) 1 valve.

In the near future I will also use it to control some lights in the garden.

All out of the box OS. No custom development

[Wokkeltje]

Yes, I am from Belgium and a happy OS user (except that it would be nice if more ‘rain days’ are taken into account to decide the watering percentage)

[Wokkeltje]

My suggestion still remains.

Zimmerman method that takes the precip from the past week into account.
lets say I want to have 10l of water per week.
If it rained 4l in the last 7 days, watering % is about 1/7th of the remaining 60% irrigation.

My current problem is that on day 1 it rains 10l, on day 2 no rain, but on day 3, the irrigation % will be 100% (if I only take rain into account)
I would like to see more impact of rain in the last couple of days.

I know that I can create my own script, but I think this is something more users can benefit from.

There are also discussions with flow meters and logging to have exact the 10l per week and this is maybe the ultimate goal, but an easy solution between current and ultimate solution would be nice?

[Wokkeltje]

Next to “when”, I may have a question “what” is in the pipeline for the next release (releases)
Is there a list of features that are planned in the (near) future?

thanks.

[Wokkeltje]

Thanks

shutdown-button

[Wokkeltje]

any idea for the release date? (days, weeks, months, …) ?

just to have an idea, not to pin you to a date

[Wokkeltje]

I don’t think changing the weight to 50% does the trick, since changing it to 50% wil modify the impact of 1l of rain to only 0,5l. It would work if I could change the weight for rain to 200% but this is not supported in the GUI.

Can I run the weather script on my rasparyPI? This would be great.
Where do I need to modifythe setting to not use the script on your server but on a local server?

[Wokkeltje]

The zimmerman calculation is

The formula used to set the scale is as follows:
• Humidity: Average humidity for the previous day above 30% is subtracted from the weather adjustment, below 30% is added to it. Example: 77% Max Humidity + 26% Min Humidity / 2 = 51% Avg Humidity, 30% – 51% Avg Humidity = -21% Humidity Adjustment
• Temperature: +4% for each degree Fahrenheit above 70, and -4% for each degree Fahrenheit below 70.
• Precipitation: -2% for each hundredth of an inch precipitation from today and yesterday. Example: 0.12″ rain today + 0.05″ rain yesterday * 100 = 17 hundredths of an inch of rain * -2 = -34% Precipitation Adjustment

So I would suggest to have the 3 parameters configurable:
* For Humidity: be able to modify the 30%
* For temp: be able to modify the +-4%
* For Precep: be able to modify the +-2%

With this extra addition, I think everybody can build its own custom Zimmerman method that fits his needs.

The ultimate would be to have also more impact of historical rain (in my region). Because sometimes it rains during a thunderstorm 30l, so this means the next couple of days no irrigation is needed. With the Zimmerman method only the previous day is taken into account.
But I know it is difficult to create a rule for this because going more days in the past has a lot more items that will influence the decision how much to water.

[Wokkeltje]

To be clear, the script isn’t mine, I just found it on the Internet.

Credits go to the person who posted the YouTube video.

[Wokkeltje]

Here is the part of the script I mentioned earlier

# Setup where we will get our IP address
url = 'http://checkip.dyndns.org'
print ("IP address service: ", url)

# Open up the url, then read the contents, and take away the IP address
request = urlopen(url).read().decode('utf-8')
# We extract the IP address only
ourIP = re.findall("\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}", request)
ourIP = str(ourIP)
ourIP = ourIP[2:len(ourIP)-2]
print ("Current IP: ", ourIP)

Complete script see YouTube link above

[Wokkeltje]

If you have the OS running on Raspberry, I have a script that sends an email if the IP is changed.

Files attached that you can schedudule every x hours using cron.

Of course it would be nice if this was build in in the OS firmware and written in the OS-account. +1 for this

[Wokkeltje]

Ok, no probleem.

I was thinking on this function because I needed to shutdown the unit to make a backup of my sdcard.

Will jeep using putty then

[Wokkeltje]

Indeed, a complete shutdown with manual action to start it again by reconecting it to the power cord.

Reason for the shutdown is maybe when you need to work on the powersupply or so.

Indeed in most cases a reboot is what you need, but a shutdown is sometimes needed.

[Wokkeltje]

Did some more investigation and really can’t find a link between Wunderground and what my OS is reporting.

I even created an xlsx file so I can test the Zimmerman Adjustment (even with the 2.1.5 update included).
But still every number is different than what OS is showing. (even the Current % Watering is not the same)
Can someone please tell me what I do wrong?

Attached is the xlsx file that contains the formulas and the info shown in OS and on Wunderground (screenshots are taken on the same moment and on the moment OS has just updated the weather info.

New version of my config is:
