Hi
I have a ESP8266 up and running on my WLAN and I want to send an analog to a RedMatic mysensors Node.
Has anybody such a config in place ?
https://www.npmjs.com/package/node-red-contrib-mysensors

cheers and thanks in advance

Hey Folks
Thank's a lot, the issue is solved. nodeMCU as a gateway measures the temperature, pass it over to an iobroker / mysensors instance. There with a JavaScript, I set a Homematic System Variable which is displayed in the iPad.
So now, I know, when the coffee machine has the right temp.

cheers

ok, looks better, I included the library from Paul Stoffregen and commented out #define MY_RADIO_RFM69.
So far no exception. I still can join my home WLAN, but sensor data can not be read.
All I Need is a temp sensor and send the data do a iobroker instance.

The question is whether I'm on the right track with a nodeMCU ?

yes, but i'm not shure whether this is correct
All I Need is a sensor that sends the temperature via WLAN to UDP Port 5003 of the iobroker (acting as Controller)

Could also be an Arduino Nano with a Radio, e.g. NRF24L01

Hi, yes, the Hardware is ok. running a Dallas example script shows the temperature from the sensor.
The Gateway is on the Network, I see a DHCP request and get Messages on the iobroker.

ok, i'll try, hmmmm how to import / use this lib ?

Yes I use one DS18B20.

ok, yes lokks like this. A soon as I try to get temp values then I run into an exception again.

void loop() {
  // Send locally attached sensors data here
  Serial.print("Requesting temperatures...");
  sensors.requestTemperatures(); // Send the command to get temperatures
  Serial.println("DONE");
  delay(1000);
}

Hey great, I started with a new sketch and did what You recommended. I get the number of sensors now without exception and stack trace. On a good way now I guess. Many thank's and best regards from Switzerland

ok, I'll give it another try. Learning by doing :-)
Starting with the ESP8266 example and adding the Dallas Temp parts ?

Ok, thank You. So how I declare MySensor gw; in mysensors Version 2 ?

Hi since I am new to mysensors, I starting with examples, don't have much experience right now.
Here is my sketch.

#include <ESP8266WiFi.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <EEPROM.h>
#include <SPI.h>

// Enable debug prints to serial monitor
#define MY_DEBUG

// Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
#define MY_BAUD_RATE 115200

// Enables and select radio type (if attached)
#define MY_RADIO_RFM69
#define MY_GATEWAY_ESP8266

// Enable UDP communication
#define MY_USE_UDP
#define MY_PORT 5003 

// Set the hostname for the WiFi Client. This is the hostname
// it will pass to the DHCP server if not static.
#define MY_ESP8266_HOSTNAME "nodeMCUTemperatureECM"   

// How many clients should be able to connect to this gateway (default 1)
#define MY_GATEWAY_MAX_CLIENTS 2

// 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. 
#define MY_CONTROLLER_IP_ADDRESS 192, 168, 1, 152

// Enable inclusion mode
#define MY_INCLUSION_MODE_FEATURE

// Enable Inclusion mode button on gateway
// #define MY_INCLUSION_BUTTON_FEATURE
// Set inclusion mode duration (in seconds)
#define MY_INCLUSION_MODE_DURATION 60 
// Digital pin used for inclusion mode button
#define MY_INCLUSION_MODE_BUTTON_PIN  3 

// Flash leds on rx/tx/err
// #define MY_LEDS_BLINKING_FEATURE
// Set blinking period
// #define MY_DEFAULT_LED_BLINK_PERIOD 300

// Led pins used if blinking feature is enabled above
#define MY_DEFAULT_ERR_LED_PIN 16  // Error led pin
#define MY_DEFAULT_RX_LED_PIN  16  // Receive led pin
#define MY_DEFAULT_TX_LED_PIN  16  // the PCB, on board LED

#include <WiFiUdp.h>
#include <MyConfig.h>
#include <MySensors.h>

#define ONE_WIRE_BUS 2
#define MAX_ATTACHED_DS18B20 4
int numSensors=0;
OneWire oneWire(ONE_WIRE_BUS); // Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
DallasTemperature sensors(&oneWire); // Pass the oneWire reference to Dallas Temperature.

void setup() {
  //sensors.begin();
}

void presentation() {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("nodeMCUTemperatureECM", "1.0");
  // Fetch the number of attached temperature sensors  
  numSensors = sensors.getDeviceCount();
  
  Serial.print("----------------- # of Sensors found >>> ");
  Serial.println(numSensors);
  
  // Present all sensors to controller
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i, S_TEMP);
  }
}

void loop() {
  // Send locally attached sensors data here
  Serial.print("Requesting temperatures...");
  sensors.requestTemperatures(); // Send the command to get temperatures
  Serial.println("DONE");
  delay(1000);
}

Yes I have the same Situation. nodeMCU with mysensors 2.0 and ESP8266 board version 2.3.0.
See Article https://forum.mysensors.org/topic/4983/nodemcu-my_gateway_esp8266-and-temp-sensor

Using mysensors 2.0 on a nodeMCU, I can deploy the DS18B20 to read temp values. Secondly using the mysensors Gateway works to join the WLAN and sending Messages to iobroker mysensors instance.

I found another script where MySensor gw; is declared, but this gives me an error. And in the same example #include MySensor.h is declared. But I have to use #include MySensors.h. Is this a matter of mysensors Version ?

This is the code, errormessage and stack info follows, many thanks.

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
float prevTemp = 0;
int sent = 0;
int numSensors=0;

void setup(void)
{
// start serial port
Serial.begin(115200);
Serial.println("Dallas Temperature IC Control Library Demo");

// Start up the library
sensors.begin();
}

void presentation() {
// Send the sketch version information to the gateway and Controller
sendSketchInfo("Temperature Sensor", "1.1");
// Fetch the number of attached temperature sensors
numSensors = sensors.getDeviceCount();
// Present all sensors to controller
for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
present(i, S_TEMP);
}
}

void loop(void)
{
// call sensors.requestTemperatures() to issue a global temperature
// request to all devices on the bus
Serial.print(" Requesting temperatures...");
//sensors.requestTemperatures(); // Send the command to get temperatures
Serial.println("DONE");

Serial.print("Temperature for Device 1 is: ");
//Serial.print(sensors.getTempCByIndex(0)); // Why "byIndex"?
// You can have more than one IC on the same bus.
// 0 refers to the first IC on the wire

delay(1000);

}

Have this up and running on a nodeMCU. WLAN ist ok, get data on iobroker/mysensors instance.
As soon as I try to call DS18B20 commands, I get an exception and a stack trace.

DS18B20.requestTemperatures();

What causes this ?

Hmm, as soon as I omit including <MySensors.h> it works. I use mysensors 2.0 in Arduino IDE

Hi, I have iobroker running on a rasPi3 and an instance of mysensors configured. This is working so far. On a nodeMCU, mysensors 2.0 is used. I can pass data between.

cheers
