Opinions on Arduino based cable connection

[febalci]

Hi all,

Planning a Domoticz installation on Raspberry Pi. For sensors, i have cabled reed switches and cabled PIRs. What i am planning is to collect all sensor cables to an Arduino Mega IO, and send all switch status from the Arduino to Rpi from ethernet shield. I have no intention of using wireless in any sensors or Domoticz connections. So;

May i get your suggestions on the protocol for the Arduino Mega+ Ethernet Shield to Raspberry Pi connection? Should i use direct JSON calls from arduino to domoticz, or should i use MQTT or anything else? Which would be the more efficient way? As i understand from mysensors, it is mainly for wireless sensors. What would be the way to go for wired sensors?

EASY ESP ?

Exactly as you wanted only not an ethernetshield but Wifi instead and no programming skills required.

I have several ones and one with 4 sensors connected to my domotics.

Thanks frejin,

i checked it out; looks great. However, any wireless protocol is not wanted specifically. The cables for the sensors in the house are already laid out and it is specifically wanted that these cables are to be used. As i understand from Easy ESP it is wifi connected with ESP8266. So, unfortunately it won't be of use for me in this project, but it is great for my own usage in other projects, i will try it. Thanks again...

aha,

understand your goal..

Perhaps.. as the sources are available you can use that to rewrite from wifi to serial communication ?

I have several Arduino's with Ethernet connected to Domoticz.
One reads my electricity meter, one my boiler, one another controller and there are 3 others used for sensors/actuators.

All of them work with JSON GET requests, but I am am going to reprogram one of them for MQTT to test the difference.
The problem I have with JSON is that although sending data from the Arduino to Domoticz works fine every time, sending a command back to the Arduino from Domoticz is not fail safe in my case.

In my opinion MQTT is not really superior to JSON.
MQTT does have more overhead than a simple GET request with JSON.
The major benefit of MQTT is that it is not specific to Domoticz.
So if you create a MQTT device it can interact with many systems, whereas the JSON type is fixed to Domoticz.

My advice would also be to stick with the Wiznet ethernet shields, these have the best compatibility with Arduino.

Hi bbqkees, is it possible if you can send sample arduino sketches with the JSON calls? Thanks...

There is a plugin available for the Nodo-Mega V3.7, with nodo shield and Ethernet shield, I use it for many years.

http://www.nodo-domotica.nl/forum/viewt ... 120#p15109

The forum is dutch, not sure how google translate will solve it, and they stopped working on it.

In the end i managed to do it. Connected a total of 24 reed and PIR sensors to an arduino mega. The arduino reads on/off status of the sensors with GPIO ports and sends to domoticz with json calls. Since some of the sensor cables are long, the they required an optocoupler before connecting to the GPIO ports; because of the length related noise on the cables. The sensors were sending nanosecond on/off signals before the optocouplers.

For the lights, another arduino mega is used (a total of 20 lights, cable connection again). This time i used mysensors, stripping out the wireless parts in the .ino. Works perfectly so far. Anyone needing the .ino files and details, just ask for it...

Hello febalci,

I'am interested and need some help. I want to start simple. What do I want to achieve first?

Code: Select all

                      <---> Arduino nano <-> ethernet (ENC28J60) <-----------------------> Domoticz
relay        <<<<<<

I'am interested in your ino (s). What else is necessary on the side of Domoticz?


Thanks in advance.

Hello Jen,

First you need to make hardware connection of doorcontacts to arduino. Prefer digital pins and don't forget to put resistors. You can find info on this on the internet.
Then you have to create Dummy Switch devices in Domoticz, one per doorcontact.

On Arduino i used this .ino (For 24 door contacts and PIR sensors):

Of course, this .ino assumes all the sensor connections are of wired type. There's no wireless connections in this .ino.

Btw i didn't get the usage of relay in your assumption. Door contacts are only one side status devices. And this .ino is working like a Security Alarm. The status is sent only one way to Domoticz. Good Luck.

You don't need an arduino for reed switches, it can be done very easily with just a Raspberry Pi.

See: viewtopic.php?f=65&t=24991&p=192239#p192239

I've got a Pi 3 B+ which only monitors a reed switch working very nicely.

Thanks for the answers.

@febalci: I will try. At the moment I do not need it immediately because I use a few pifaces. I just want to learn how to connect an arduino with connected sensors and actuators via Ethernet to Domoticz. I think I'am a step further.

Hi Febalci,

just used your code for Arduino, I have edited the file to suit my needs i.e. IP address, ports etc.
I have commented out nearly all the inputs apart from the 1st one
#define PIN_MUTFAK_SU 4
int MUTFAK_SUStatus = UNKNOWN;
int IDX_MUTFAK_SU = 44;

Anything related to MUTFAK_SU I have left in every other device I have commented out.
I created a dummy switch in Domoticz and in SETUP/HARDWARE it has an IDX of 44 however in setup devices
517 MUTFAK_SU 00014255 1 MUTFAK_SU Light/Switch Switch Off

I have swapped between 517 and 44 no difference.
I have wired the switch as per the diagram attached but to pin 4
if I run serial monitor I can see the switch turning on and off although it switches on/off /on/off when switched
but I still see nothing in Domoticz nothing in the log, although my Domoticz does require a password i'm not even getting a failed to connect or similar.
Any ideas will be greatly appreciated as this is exactly what I am looking for.
I have a hardwired alarm system and can use the existing devices to control scenes.
cheers

Dear alarmguy,

the IDX you should be using in the .ino is in the Setup/Devices Page. So, you should use 517, not 44... In case there might be some typo or something i post you here the 1 input code. Please use this .ino:

Code: Select all

// SPI and Ethernet is needed for Ethernet shield

#include <SPI.h>

#define PIN_MUTFAK_SU               517

// Last Status of the Sensors
int MUTFAK_SUStatus	=               UNKNOWN;

// IDX numbers of PIR and Reed Contacts on Domoticz-Devices Page

int IDX_MUTFAK_SU =             31;

  
// Arduino MAC ve IP addresses

  int currentStatus;
  const char* msg = NULL;

  currentStatus = contactState(PIN_MUTFAK_SU);
  if (MUTFAK_SUStatus != currentStatus)
  {
    MUTFAK_SUStatus = currentStatus;
    if(MUTFAK_SUStatus == CLOSED) msg = "Off";
    else                     msg = "On";
    httpRequestswitch(IDX_MUTFAK_SU, msg);
    return; // only one message per loop
  }

}


void setup() {
  pinMode(PIN_MUTFAK_SU , INPUT);
  
#if DEBUG

Also, which Arduino and ethernet shield you are using?

[alarm_guy1]

Thankyou for the quick response.
I shall give it a go now I have arrived home.
Im running an Uno with an Ethernet Shield 2 on it

I'll let you know how I get on

Cheers

Attached is the modified Code for my system with IP address and port

Code: Select all

#define PIN_MUTFAK_SU               1 

// Last Status of the Sensors
int MUTFAK_SUStatus  =               UNKNOWN;

// IDX numbers of PIR and Reed Contacts on Domoticz-Devices Page

int IDX_MUTFAK_SU =             517;

  
// Arduino MAC ve IP addresses

byte mac[] = {
  0xDE, 0xAD, 0xBE, 0x30, 0x39, 0x01};//Random address

IPAddress domoticz(192,168,2,137); // Domoticz IP Address
int port = 8081; // Domoticz Port No
EthernetClient client;


//httprequest functions, sends status info to Domoticz

// /json.htm?type=command&param=switchlight&idx=XX&switchcmd=On
void httpRequestswitch(int IDX, String status) {
  // When the connection is successful:

    client.println( "Connection: close");
    client.println();

    client.println();
    client.stop();
    delay(150);
  } 
  else {
    client.stop();
  }
}


int contactState(int pin)
{
  // LOW  -> CLOSED
  // HIGH -> OPEN
  return (digitalRead(pin) == HIGH)?OPEN:CLOSED;
}

void updateContactStatus()
{
  int currentStatus;
  const char* msg = NULL;

  currentStatus = contactState(PIN_MUTFAK_SU);
  if (MUTFAK_SUStatus != currentStatus)
  {
    MUTFAK_SUStatus = currentStatus;
    if(MUTFAK_SUStatus == CLOSED) msg = "Off";
    else                     msg = "On";
    httpRequestswitch(IDX_MUTFAK_SU, msg);
    return; // only one message per loop
  }

}


void setup() {
  pinMode(PIN_MUTFAK_SU , INPUT);
  
#if DEBUG  
  Serial.begin(9600);
  Serial.println("Arduino Alarm - Domoticz Connection");
#endif 

  Ethernet.begin(mac, ip);

#if DEBUG
  Serial.print("Arduino IP addresss: ");
  delay(1000);
  Serial.println(ip);
#endif  

}


void loop()
{
  updateContactStatus();
}

When I run serial monitor and I close my switch nothing happens, when I open my switch then I get the switchcmd=on
but I get no off, the the switch wont follow the status.
However in Domoticz my dummy switch does not change state, I can ping the arduino no problem, so now I am stuck.

Hope you can help cheers

[alarm_guy1]

this is how my contact is wired too

As i see; in your .ino file you are missing the #define OPEN 1:

Code: Select all

#define CLOSED                  0     // LOW
#define UNKNOWN                 2     // --- reset / force update

#define OPEN		1  // ADD THIS LINE

Please try this on firefox or chrome internet client on any pc on your network: Write the following to address and press Enter:

Code: Select all

http://192.168.2.137:8081/json.htm?type=command&param=switchlight&idx=517&switchcmd=On

and:

Code: Select all

http://192.168.2.137:8081/json.htm?type=command&param=switchlight&idx=517&switchcmd=Off

Check your domoticz device 517 after these commands, one turns switch on and the other off. Are they working this way?

Right sorry my code did not upload correctly last time Define open is in there.

These lines work fine in Chrome
http://192.168.2.137:8081/json.htm?type ... tchcmd=Off
http://192.168.2.137:8081/json.htm?type ... itchcmd=On

when you start up your serial monitor does yours look the same as mine?

cheers for continued help, I am assuming for some reason the Uno and shield are not talking to Domoticz, this area is all completely new to me sorry
