Problem with sensors on arduino and domoticz

[hyperflemme]

Hi everyone,
to begin I want to apologize for my level of English, I am French.

I have a problem, i have an arduino mega 2560 and i want associate him with a rasberry pi 3 using an USB cable. into my arduino i have plugged lot of sensors (Motion sensor PIR sensor V1.0; DHT11 sensor; O2 sensor, CO2 censor and light sensor). I have use this gateway for associate him:

* 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

juste after i have connected my arduino card into my rasberry pi3
and she recognized the arduino card. so i put an motionsensor example like this:

my rasberry card does not recognize my sensor, can you help me?

[Nca78]

Hello,

can you please :

• tell us what controller you are using, and if your gateway was successfully added to it, with gateway responding to the controller ?
• enable debug mode in your sensor sketch (remove // before "#define MY_DEBUG" line) and tell us what you see in the log ?

[bjacobse]

Domoticzs guide, do you have the mysensors gateway defined in Domoticz?

https://www.domoticz.com/wiki/MySensors

[bjacobse]

in a shell try to type "dmesg |grep tty"
then there should be something that shows that a ttyUSB0 or ttyUSB1 devices is attached

[kimot]

Do you connect your sensor to the same mega2560 which works like serial gateway or are you using different mega2560 connected through radio to serial gateway mega2560?

[hyperflemme]

@nca78 Hi,
I use an arduino mega 2560, the gateway was successfully added on arduino.
for MYDEBUG i will test this today

[hyperflemme]

@kimot I have only 1 arduino, i have put the gateway into this card.

[hyperflemme]

@nca78 Hi,

Look this and help me please. sketch for motion sensor.

[Nca78]

@hyperflemme you can check the log using the log parser
https://www.mysensors.org/build/parser

Here it says it cannot connect to parent, is you gateway active, and on the same radio channel ?

[hyperflemme]

@nca78 what do you mean by log parser?
i just have put a gateway usb into arduino.

[hyperflemme]

@nca78

[Nca78]

@hyperflemme as you can read "no potential parents replied to find parent request". It means no gateway replied to the radio calls.

Please describe your full mysensors installation if you want help :

• controller used ?
• board, radio used for gateway ?
• board, radio used for sensor ?

[kimot]

@hyperflemme
Than in your second sketch ( with sensors )
define MY_GATEWAY_SERIAL
is missing.
This sketch works like normal node without this, not as gateway with sensors connected.

[hyperflemme]

@nca78 Hi,
I just have an nrf24l01 plug into my arduino.

I miss something to make it work?
Thank's for helping me

[hyperflemme]

@kimot in my sketch for motion sensor you think i just have to had #define MY_GATEWAY_SERIAL on the top of the program?

Thank's for your help

[Nca78]

@hyperflemme said in Problem with sensors on arduino and domoticz:

@kimot in my sketch for motion sensor you think i just have to had #define MY_GATEWAY_SERIAL on the top of the program?

Thank's for your help

The arduino that is connected to computer with USB should have #define MY_GATEWAY_SERIAL yes, so it will behave as a gateway and send the data to the computer. You need to configure it in your controller (home automation software) also.

If you have 1 gateway (arduino + radio) connected to computer + 1 sensor (arduino + radio) separated then the sensor should not have this #define.

[hyperflemme]

@nca78 all my sensor are connected on the arduino card with nRF24L01, and the arduino card is connected by usb on my computer. I want tu connect the arduino card at an raspberry pi 3 but she don't recognise arduino card and sensor, however i have put the gateway and sketch of sensor into the arduino card....

[Nca78]

@hyperflemme what controller software are you using on the raspberry pi ?

[hyperflemme]

@nca78 Linux on raspberry pi 3 with domoticz

[Nca78]

@hyperflemme did rebuild the gateway script with #define MY_GATEWAY_SERIAL ?
Then did you add the gateway in the hardware tab of domoticz ?

[hyperflemme]

@nca78 domoticz recognize the arduino card, his version of gateway, but into hardware tab if i change the card i have an children "Unknown" with id 3 and an other child unusable with a ID 255.
in the log of domoticz i have "Gateway ready"

[Nca78]

@hyperflemme so it's good news domoticz can see your gateway.

Can you post the script you are using now ?

[hyperflemme]

@nca78 the script of the gateway or the script of one of the sensors?
I give you both juste here:
for the gateway i just use this: https://www.mysensors.org/build/serial_gateway and i just added this before inclide mysensors.h:

#define MY_RF24_CE_PIN 49
#define MY_RF24_CS_PIN 53

the script of the sensors is:

for motion sensor i use a PIR Sensor V1.0

[kimot]

I think we still do not know the topology of your network and we use different terms.
For most of us a "sensor" is - temperature sensor, humidity sensor, pressure sensor, etc. These sensors are connected to Arduino, which we call the "node".
These node are connected through radio or RS485 to Arduino which works like gateway and send received messages from nodes to controller ( Rpi with Domoticz ).
Usually gateway have got no sensors and you can use pure gateway sketch from examples.
But you can connect sensors directly to gateway, but you must modify gateway sketch then.

• setup your sensors
• present your sensors
• send values form your sensors.

And of course NO SLEEP FUNCTION in sensor send code.

Places, where put it is marked by comments in gateway sketch:

void setup()
{
    // Setup locally attached sensors
}

void presentation()
{
    // Present locally attached sensors
}

void loop()
{
    // Send locally attached sensor data here
}

Usual topology:

I think your topology:

[hyperflemme]

@kimot Hi , tank's for your help,
my topology:

how can i do?

[kimot]

@hyperflemme
Use gateway sketch and add sensor presentation and sensor data sending like in node sketch.

example from this forum:

void presentation() {
  // Present locally attached sensors here
    // Send the sketch version information to the gateway and Controller
  sendSketchInfo("AWI_ESP 120", "1.0");

  // Register all sensors to gw (they will be created as child devices)
  present(CHILD_ID, S_DIMMER, "AWI_ESP 120" " dimmer");
  present(CHILD_ID2, S_INFO, "AWI_ESP 120" " text");

}


void loop() {
  // Send locally attached sensors data here
 	send(msg.set(messageCounter)); 										// Send message to gw 
	messageCounter = ++messageCounter % 100 ;							// wrap
	send(msg2.set("Hallo")); 											// Send message to gw 
	// Send update every SLEEP_TIME
	wait(SLEEP_TIME) ;
}

void receive(const MyMessage &message) {  								// messages from node or controller
	//char printBuf[40] ;
	//Serial.print(message.getInt());
		//sprintf(printBuf, "Message node: %d %d  OK\n", message.sender, message.getInt());
}
	//Serial.print(printBuf) ;
	//sprintf(printBuf, "Messages: %d Errors: %d\n", messageCounter, messageErrorCounter);
	//Serial.print(printBuf) ;

Search forum here, you are not alone with this solution.

@kimot THANKS !!!
for 1 sensor it's ok, but if i had a 2nd sensor he doesn't work...
