disabled MY_USE_UDP and it's connecting now... Thanks, feel pretty stupid.. Attaching the humidity sensor does cause de gateway to a reboot loop. Could that be a power issue since it's connected to my laptop's usb right now?

Because further down is stated:

// Controller ip address. Enables client mode (default is "server" mode).
// Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere.

My assumption was that I want it both to be a client and have it's data send to my domoticz controller, but obviously this isn't the way to go..?

I tried it the other way around, but still no improvement.

the number 65535 keeps being printed like every second, which seems strange to me.

gateway address must be my internet gateway right? In that case 192.168.2.254 is correct.
#define MY_CONTROLLER_IP_ADDRESS 192, 168, 2, 1 is my Domoticz server. Is that the way to go or am I doing something wrong?

Hi,

I'm trying to use a esp8266 gateway as a standalone node and let it connect to Domoticz. After some hick ups I managed to compile my sketch. The gateway boots, but I'm not sure if it gets connected the right way. Serial log shows:

0‚~?–$û!ƒ{ƒOAaû0;255;3;0;9;Starting gateway (R-NGE-, 2.0.0-beta)

In Domoticz I've added a Mysensors Lan Gateway in Hardware, with remote address 192.168.2.242 and port 5003. Which is opened in my router for 192.168.2.242. Domoticz log keeps showing:

2016-02-22 12:48:16.489 Error: MySensors: Error: Connection refused
2016-02-22 12:48:16.490 Error: TCP: Error: Connection refused

The inclusion button in the sketch is disabled, but inclusion time is set to 60 seconds. Could this be part of the problem?
Hope someone can help..

My sketchbook location is set to E:\documenten\Arduino and it contains the MySensors library. I think I was using 1.5 before so I removed all libraries and extracted everything from the 2.0 zip to that folder, Now compiling gives me this:

Manualy include the eps8266wifi library on top of the sketch did the trick. Despite the fact that these libraries where included later on in the sketch. @hek, thanks for puting me on the right track!

I've removed all libraries and reinstalled the board manager.. Have you seen this before?

Thanks very much for your quick reply! Now suddenly I get compiling errors saying there is no such file as espwifi8266.h, which is weird because it was compiling other sketches just fine. Reinstalling libraries and the board manager now....

I'll let you know whether this works. Thanks again!

Hi,

I'm trying to use a nodemcu 0.9 as a standalone node using wifi and not the radio to connect to my Domoticz. Using the ESP8266 gateway i'm facing a problem. I've added the setup and loop part to it from a sketch I used earlier on a node with a traditional radio on it.
My guess is that trying to use the wifi connection to send data the commands in a sketch must be slightly different, but I have no idea how and can't find useful examples. Using this code gives me an error compiling in the line MySensor gw; , saying 'MySensor' does not name a type.

Can anyone help me out?

@ericvdb
Hi, yeah sorry for that. I only realised that when I took a closer look at your sketch because it gave me the check wires message..
Thanks a lot, I've now put the radio on a seperate pin too powering it down and let the radio reinitialize by using gw.begin(); in the void loop section.

This is the final code now and it is working well!

#include <SPI.h>
#include <MySensor.h>

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 1
#define MIN 300  // Liquid
#define MAX 700 // Air

int sensorPin = A0; // select the input pin for the potentiometer
int sensorValue = 0; // variable to store the value coming from the sensor
int power =4;
int radio =5; 
MySensor gw;
MyMessage msg(CHILD_ID_LIGHT, V_HUM);
int lastLightLevel;

void setup(){
pinMode(power, OUTPUT);
digitalWrite(power, HIGH);
pinMode(radio, OUTPUT);
digitalWrite(radio, HIGH);
delay (5000);
Serial.begin(9600);
gw.begin();

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Mobile Sensor 1", "Kruiden");

// Register all sensors to gateway (they will be created as child devices) 
gw.present(CHILD_ID_LIGHT, S_HUM);

digitalWrite(power, LOW);
}

void loop(){
// Turn sensor On
digitalWrite(power, HIGH);
// Turn Radio on 
digitalWrite(radio, HIGH);
// read the value from the sensor:
delay (5000);
gw.begin();
sensorValue = analogRead(sensorPin);


int lastsensorValue = sensorValue;

Serial.println(sensorValue);
int sendValue =  map(sensorValue, 0, 842, 0, 100); 
gw.send( msg.set( sendValue ) );
// Turn sensor Off
digitalWrite(power, LOW);
// Turn radio off
digitalWrite(radio, LOW);
gw.sleep(3600000);  
}```

Cheers, when only powering down the sensor it is working now! Is there a way to reinitialize the radio after powering it down or do you know of other ways to reduce the power usage of the radio?

Hi, thanks for your reply. I was using delay so much because it seemed that the radio and sensor both needed some time to start up after they were powered on by puting pin 4 high.

Using your sketch wasn't working because both the radio and sensor are powered by the same pin. In the Void setup the pin was not set high so the node and radio were not started and it would not come to the loop part of thee sketch.

Also I've put the digitalWrite low at the end before puting it to sleep, because otherwise it would not sent anything because being powered off.

Making this small changes to your sketch still made it be presented to the gateway only once. Could there be a problem in puting pin 4 high both in the setup and the loop part? This is the code right now...

#include <SPI.h>
#include <MySensor.h>

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 1
#define MIN 300  // Liquid
#define MAX 700 // Air

int sensorPin = A0; // select the input pin for the potentiometer
int sensorValue = 0; // variable to store the value coming from the sensor
int power =4;
MySensor gw;
MyMessage msg(CHILD_ID_LIGHT, V_HUM);
int lastLightLevel;

void setup(){
pinMode(power, OUTPUT);
digitalWrite(power, HIGH);
Serial.begin(9600);
gw.begin();

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Mobile Sensor 1", "Kruiden");

// Register all sensors to gateway (they will be created as child devices) 
gw.present(CHILD_ID_LIGHT, S_HUM);

}

void loop(){
// Turn sensor On
digitalWrite(power, HIGH);
// read the value from the sensor:
delay (5000);
sensorValue = analogRead(sensorPin);


int lastsensorValue = sensorValue;

Serial.println(sensorValue);
int sendValue =  map(sensorValue, 0, 842, 0, 100); 
gw.send( msg.set( sendValue ) );
// Turn sensor Off
digitalWrite(power, LOW);
gw.sleep(60000);  
}

Hi there,

I'm having a sketch problem.. In order to try and save battery power on my moisture sensors I'm trying to use a IO pin as power by setting it high for some time, let the sensor take a measurement, send the results to the gateway, setting the IO pin low again, let the node go to sleep for some time .

This works only one time, the node presents itself to the gateway, sends data but after that it's not seen again after the expected sleep time.
My guess was that somehow after puting the IO pin low it doesn't come back up in a high state. The strange thing is that when I measure the current on the pins of my moisture sensor with a multimeter the current goes from 0 to aprox 4.27V in the given time, so actually that indicates the pin is going from high to low and back to high as needed, but somehow the radio doesn't come back up... This is my code:

#include <SPI.h>
#include <MySensor.h>

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 1
#define MIN 300  // Liquid
#define MAX 700 // Air

int sensorPin = A0; // select the input pin for the potentiometer
int sensorValue = 0; // variable to store the value coming from the sensor
int power =4;
MySensor gw;
MyMessage msg(CHILD_ID_LIGHT, V_HUM);
int lastLightLevel;



void setup(){
pinMode(power, OUTPUT);
digitalWrite(power, HIGH);
delay(3000);
Serial.begin(9600);

gw.begin();

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Mobile Sensor 1", "Kruiden");

// Register all sensors to gateway (they will be created as child devices)
gw.present(CHILD_ID_LIGHT, S_HUM);

delay (2000);
}
void loop(){
// read the value from the sensor:


digitalWrite(power, HIGH);
delay (5000);
sensorValue = analogRead(sensorPin);
delay(1000);
int lastsensorValue = sensorValue;
 
Serial.println(sensorValue);
int sendValue =  map(sensorValue, 0, 842, 0, 100); 
  gw.send( msg.set( sendValue ) );
 delay(10000); 
digitalWrite(power, LOW);
delay (2000); 
gw.sleep(60000);  
} 

Does anyone have any clue..?

Hi there,

I'm having another sketch problem.. In order to try and save battery power on my moisture sensors I'm trying to use a IO pin as power by setting it high for some time, let the sensor take a measurement, send the results to the gateway, setting the IO pin low again, let the node go to sleep for some time .

This works only one time, the node presents itself to the gateway, sends data but after that it's not seen again after the expected sleep time.
My guess is that somehow after puting the IO pin low it doesn't come back up in a high state. The strange thing is that when I measure the current on the pins of my moisture sensor with a multimeter the current goes from 0 to aprox 4.27V in the given time, so actually that indicates the pin is going from high to low as needed, but somehow the radio doesn't come back up... This is my code:

#include <SPI.h>
#include <MySensor.h>

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 1
#define MIN 300  // Liquid
#define MAX 700 // Air

int sensorPin = A0; // select the input pin for the potentiometer
int sensorValue = 0; // variable to store the value coming from the sensor
int power =4;
MySensor gw;
MyMessage msg(CHILD_ID_LIGHT, V_HUM);
int lastLightLevel;



void setup(){
pinMode(power, OUTPUT);
digitalWrite(power, HIGH);
delay(3000);
Serial.begin(9600);

gw.begin();

// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Mobile Sensor 1", "Kruiden");

// Register all sensors to gateway (they will be created as child devices)
gw.present(CHILD_ID_LIGHT, S_HUM);

delay (2000);
}
void loop(){
// read the value from the sensor:


digitalWrite(power, HIGH);
delay (5000);
sensorValue = analogRead(sensorPin);
delay(1000);
int lastsensorValue = sensorValue;
 
Serial.println(sensorValue);
int sendValue =  map(sensorValue, 0, 842, 0, 100); 
  gw.send( msg.set( sendValue ) );
 delay(10000); 
digitalWrite(power, LOW);
delay (2000);
gw.sleep(60000);
}
 

Does anyone have any clue..?

Hi, like someone mentioned above no controller is perfect but I can only tell you what I'm using for the same purposes as you intend, Lightning, Curtains, Irrigation en a couple of sensors.

I've been running Domoticz on a Raspberry pi for over a year now with great pleasure. Together with a RFXCOM transeiver which is able to send 433mhz signals to wide range switches etc.

For Z-wave there are USB-dongles or shields that can be easily attached to the Rasberry Pi. Besides that I have an Arduino Uno attached to the pi to act as a Mysensors gateway.

As I said I'm not sure if this is the best way to go, but it fits my needs perfectly. Accept for the transeiver all the hardware is relatively cheap, easy to get and low on power consumption.

However it's not realy a specific Mysensors matter I thought it might be usefull for others suffering on the same problem. It turned out that the Rpi and Domoticz crashed after being presented more than 1 node due to some 1Wire issue. Strange thing is I wasn't even using 1wire.

Disabling it running sudo rmmod w1_gpio did the trick. Domoticz is running stable and taking as by now, four nodes without any problem.

Working like a charm now! Thank you very much for your help!!

When i set batteryPcnt back to int it shows: no matching function for call to 'MySensor::send(int&)'

Do i have to use a different command to send the battterypcnt to the gateway?

gw.send(batteryPcnt);

gives this error:

no matching function for call to 'MySensor::send(float&)'
