/*
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.
* Pushbutton activation to RUN_ALL_ZONES, RUN_SINGLE_ZONE or halt the current program
* LED status indicator

PARTS LIST:
Available from the MySensors store - http://www.mysensors.org/store/
* Relays (8 channel)
* Female Pin Header Connector Strip
* Prototype Universal Printed Circuit Boards (PCB)
* NRF24L01 Radio
* Arduino (I used a Pro Mini)
* FTDI USB to TTL Serial Adapter
* Capacitors (10uf and .1uf)
* 3.3v voltage regulator
* Resistors (270, 1K & 10K)
* Female Dupont Cables
* 1602 LCD (with I2C Interface)
* LED
* Push button
* Shift Register (SN74HC595)
* 2 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 3 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 22-24 gauge wire or similar (I used Cat5/Cat6 cable)
* 18 gauge wire (for relay)
* Irrigation Power Supply (24-Volt/750 mA Transformer)


INSTRUCTIONS:

* A step-by-step setup video is available here: http://youtu.be/l4GPRTsuHkI
* After assembling your arduino, radio, decoupling capacitors, shift register(s), status LED, pushbutton LCD (I2C connected to
  A4 and A5) and relays, and load the sketch.
* 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

jkandasa

@emenike Thank you for the sketch, Yes, you should keep both MySensors and MyController(Gateway) on the same port. Regards baud rate, I want to see your gateway sketch. Can you share your gateway sketch?

Emenike

@jkandasa My Gateway is the no same as the tutorial on MySensors… I didn't change anything. Or should I?

/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*******************************
*
* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on serial which will be sent out on radio network.
*
* The GW code is designed for Arduino Nano 328p / 16MHz
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
* - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or receive crc error
*

@jkandasa Okay I have reverted to Com 5 for both MySensors Gateway and Com5 for Mycontroller. I restarted the controller and I was able to connect successfully. Phew!
0_1543683298126_Screen Shot 4.png

That's done, you still didn't say if the certificate error has a role to play. I have connected the sprinkler package to an external power and I am running Putty on the side to listen to Com5 No cheese...

jkandasa

@emenike Now your sketch configuration and MyController gateway configuration looks similar.
The only thing, you should not open COM5 in any service(putty, etc.,) when you enabled in MyController.

Follows these steps,

Disable Gateway in MyController
Close your putty and other services, which is listening to the serial port
Disconnect your hardware(MySensors gateway) from the computer
Reconnect your hardware again to the computer
make sure your MySensors gateway is available in COM5
Enable your gateway in MyController
Now you should see the nodes in your MyController, if not try to run discover on MyController's discover page.

you still didn't say if the certificate error has a role to play

Certificate error is completely different than this issue. Some tutorial, You may not worry about this.

Emenike

@jkandasa Wow! That really helped, I was able to not only connect to the MyController Gateway, but two Nodes discovered and Nine sensors discovered. Thanks @jkandasa you never know how hard I tried. all along, connecting and disconnecting Arduino and Putty intermittently without knowing that I was disturbing the line. see what it now looks like. 0_1543747146086_Screen Shot 5.png

So can I continue troubleshooting my problems with this tread or should I create a new one?

jkandasa

@emenike For me, it is ok to continue here. Up to your wish.

I see the name of the sensor shows some debug message, looks like we have some issue with MyController.
Can you disable debug in MySensors gateway sketch?

// #define MY_DEBUG

To update gateway sketch, you need to disable gateway in MyController and update your gateway sketch via Arduino IDE. After a successful update, you can enable gateway in MyController.

Emenike

@jkandasa Thanks.
I disabled the MyController Gateway, then commented out the debug line on the sketch via IDE. and uploaded the sketch the the MySensors gateway @ COM5. Closed the IDE and restarted enabled the MyController Gateway --- but now one node is down while the Gateway connected successfully. 0_1543792504887_Screen Shot 6.png

Emenike

This is what ot looks like now...

0_1543792608629_Screen Shot 7.png

jkandasa

@emenike Seems all ok in MyController side.
Can you check your sprinkler node powered up and in RF coverage?

Tag

Hi All,

Sorry was out for a couple of days...,

@Emenike
jkandasa is right, as an addition you can also add the debug stuff to you sketch and hook it up to your laptop to see the debugging stuff from the sensor perspective...

If the sensor is out of range of you gateway you have some options to fix it:

you can put a repeater node in the middle between the sensor and the gateway to extend the range of your network
check your radio, exchange it for another one to rule out any radio hardware issues. (some of the radios have issues... especially the Nrf24l01 radios with the round black blob instead of a chip... believe me, I have been there and the range was approx 1.5 meters.....)
If you use the Nrf24l01, add the capacitor to the power line of the radio (tought this was a 47uf capacitor), this will also improve communication (make sure you add this on the sensor and the gateway radio!)

Emenike

@tag @jkandasa

My Sprinkler node is downstairs - just about 7 meters below the spot where the MySensors Gateway + MyController laptop is (with about 2 concrete walls separating them). Does this matter? For the records, I have capacitor on both MySensors Gateway, and the Water Sprinkler node.

Tag

Can be an issue, can you try if you see the node if it is basically next to your gateway?

Emenike

@tag Okay I will move them closer until I conclude with all the bugs, then I will move them apart and see if distance is the issue

by the way... is This project in this video a MySensors Gateway or something entirely new?

Tag

@emenike

Okay, great!,
Had a look at the link you send, it looks like mysensors, but it is something different...

skywatch

@Emenike

This bit is wrong in your gateway sketch.....

// Define a lower baud rate for Arduinos running on 8 MHz (Arduino Pro Mini 3.3V & SenseBender)
#if F_CPU == 8000000L

//#define MY_BAUD_RATE 38400
#define MY_BAUD_RATE 115200
#endif

The baud rate in the if statement should be 38400 as it says in the line above it.

It won't matter if you are using a 5V arduino, but if you were to use a 3.3V one this would be a big problem.

Emenike

@skywatch Thanks @skywatch

Please note that I am using a Nano for my gate way...
I thought the baud rate should be the same for Arduino and the Putty sniffer, I will revert to "38400"...

Tag

@emenike

Make sure that the same baudrate is used in the gateway sketch and mycontroller.....

Emenike

@tag
but that was exactly how it was until you said to change 38400 …. but it connected alright after | changed to 38400 and brought the node next to the laptop.

That part of the gateway sketch is an 'If' statement. It just tells the compilier that 'if' the board is a 3.3v 8MHz type, then reduce the baud rate to match. 8MHz boards are not reliable at 115200.
