Irrigation Controller
-
Hi and thanks to all contributors of this great project. I am fairly new to all this but a long term programmer and electronics nerd. I have recently built the Irrigation Contoller project and debugged it (I thought well until I mounted it on the wall and connected everything).
I have found a number of code issues with the example code and I am wondering the best way to update or request updates to the master. I have made a pull request for a simple update which was causing the initial setup to miss getting the VAR_1 data during the setup process - is this the right way to submit updates as I have done a lot of additional work on the code to fix a number of issues I have found. An example of this being the goGetValveTimes() routine has no delays and creates NACK requests due to bombarding the radio module with 3 requests in quick succession without then waiting for the reply. Should I post these as Github pulls or should I pop it in this forum system for update?
I have some more issues with the code and project but wanting to see the best way to provide my updates back to the community firstly.
Thanks David

Pull requests are a nice way to help programmers

Yes, PRs is the correct way of improving core library and/or examples. If you plan for big behavioral changes, it might be good to discuss it with the community first. Discussions could take place here or in a github issue.

@hek Great thanks - I am setting a pull request right now which fixes another issue with the goGetValveTimes function which causes NACKs due to 3 successive sends to the radio without any pause or delay. This is a simple bug in the code and should not really need a discussion to implement as careful analysis of the DEBUG results will always yield this error. I basically copied the setup code that reads the data - put it in the function and changed the setup to call this updated function.
There is another bug I am trying to stamp out right now which is causing the manual button start to NOT send the status updates to the controller via the radio - again this is a standard bug and may or may not get seen by many if you are not testing the manual button operation. Once this is resolved I will make a pull for it also.

OK so I have added several pull requests to Github for the irrigation controller. I thought I would now show you may take on the irrigation controller firstly a pic of my unit:
The button on the left that is glowing - turns on/off the LCD backlight as most of the time I do not want to see it and have it glowing at night - this box is mounted on a wall outside my house under the eves. The right button is the flashing led coupled with the manual operation function - I also slowed down the on time for this led again to not glow and flash as much.
As I live in Australia I regionalised the displays for none US dates and here is my final code which is setup for 6 zones. I also made a modification to always switch on Zone 8 as a master valve when any other zone is activated. My original system has a master valve which enables the water supply to the other valves and hence needed to switch this on. If you want to copy my code and remove this it is at line 500 - 501 - just remove the ' - 128' from both these lines. The rest of this code has all the fixes added to the github repo for the Irrigation Controller - enjoy.
/* MySprinkler for MySensors Arduino Multi-Zone Sprinkler Control May 31, 2015 *** Version 2.0 *** Upgraded to http://MySensors.org version 1.4.1 *** Expanded for up to 16 Valves *** Setup for active low relay board or comment out #define ACTIVE_LOW to switch to active high *** Switch to bitshift method vs byte arrays *** Changed RUN_ALL_ZONES Vera device to 0 (was highest valve) *** Added optional LCD display featuring remaining time, date last ran & current time *** Features 'raindrop' and 'clock' icons which indicate sensor is updating valve data and clock respectively *** Added single pushbutton menu to manually select which program to run (All Zones or a Single Zone) *** Added option of naming your Zones programmatically or with Vera (V_VAR3 used to store names) Utilizing your Vera home automation controller and the MySensors.org gateway you can control up to a sixteen zone irrigation system with only three digital pins. This sketch will create NUMBER_OF_VALVES + 1 devices on your Vera controller This sketch features the following: Allows you to cycle through All zones (RUN_ALL_ZONES) or individual zone (RUN_SINGLE_ZONE) control. Use the 0th controller to activate RUN_ALL_ZONES (each zone in numeric sequence 1 to n) using Variable1 as the "ON" time in minutes in each of the vera devices created. Use the individual zone controller to activate a single zone. This feature uses Variable2 as the "ON" time for each individual device/zone. Connect according to pinout below and uses Shift Registers as to allow the MySensors standard radio configuration and still leave available digital pins Turning on any zone will stop the current process and begin that particular process. Turning off any zone will stop the current process and turn off all zones. To push your new time intervals for your zones, simply change the variable on your Vera and your arduino will call to Vera once a minute and update accordingly. Variables will also be requested when the device is first powered on.

Following the instructions at https://MySensors.org include the device to your MySensors Gateway. Verify that each new device has a Variable1, Variable2 and Variable3. Populate data accordingly with whole minutes for the RUN_ALL_ZONES routine (Variable1) and the RUN_SINGLE_ZONE routines (Variable 2). The values entered for times may be zero and you may use the defaulet zone names by leaving Variable3 blank. Once you have entered values for each zone and each variable, save the settings by pressing the red save button on your Vera. Restart your arduino; verify the settings are loaded into your arduino with the serial monitor; the array will be printed on the serial monitor. Your arduino should slow-flash, indicating that it is in ready mode. There are multiple debug serial prints that can be monitored to assure that it is operating properly. * ***THIS SHOULD NO LONGER BE NEEDED*** The standard MySensors library now works. https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours Contributed by Jim (BulldogLowell@gmail.com) with much contribution from Pete (pete.will@mysensors.org) and is released to the public domain Modified David Martin.

Hi David,
I am starting with my irrigation controller and your code looks ideal.
To make sure I am using the latest, I would like to get it from GitHub. Unfortunately I really struggle with GitHub and the only reference to this code, I can find does not have any pull requests, so I'm not convinced it is correct.
Can you post a GitHub link to your updated code?
Thanks
Malcolm

@Woodside https://github.com/mysensors/MySensorsArduinoExamples/blob/master/examples/IrrigationController/IrrigationController.ino seems to be the most current version. It was last updated 4 days ago. But note that the sketch is still using MySensors 1.x so it won't work with a MySensors 2 gateway.
-
@Woodside the code in this post is the latest with one exception. I am not using the internal pullup on the waterbuttonPin any more as I have installed a cap/resistor mode to facilitate a hardware debouce. The details of this have been published in the Rain Gauge project (see troubleshooting). Apart from that the above code is fully made for AU dates and is running my system now.
The GitHub version is US date based and not AU converted but has my mods for the gateway comms and some updates - https://github.com/mysensors/MySensorsArduinoExamples/blob/master/examples/IrrigationController/IrrigationController.ino
If you run into any problems or issues let me know.

@itbeyond Hi David, thanks for the code. I have an issue with the transformer as it get very hot, and am trying to use the same arduino to control another relay to turn on the tranformer before irrigation and turn the relay off after finishing the irrigation. Please, will appreciate your help pointing out what changes to the code are needed. I was trying to use an analogic pin as digital but am having unexpected results...
pinout(A0, OUTPUT);
digitalWrite(A0, HIGH);
Thanks for any help.
