I have with succes used these:

http://www.aliexpress.com/item/Travel-Convenient-EU-Plug-Wall-USB-Charger-Adapter-For-Samsung-Galaxy-S5-S4-S3-Note-3/32220133044.html

They are really easy to dismatle, and the result is this - https://www.dropbox.com/s/ep43uyve5v0msv6/20141206_214210.jpg?dl=0

At $1.10 I didn't even think about making my own PSU

Hi,

I need some help.

I have a Node controlling my floorheating, but now I want to make a "local" override button, incl diode indicating lights.

My idea is to build it all in a clear plastic housing (so I can see the relay lights). I then thounght about using a tactile button as "override" and some 3mm leds as indicators. Green = Auto, Red = "Manuel" and Blue = Overridden.

This Is my working scetch on a Nano.

/**
 * 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.

Hi,

I'm having a hard time figuring out, why i'm getting the same value from 2 different DS18B20 from the same node. Both DS18 are on Pin 3.

I know for SURE, that the values/readings can never be the same, as they are placed 2 different places. It's ALWAYS the second DS that somehow get the first DS's value, and that is then transmitted. The node is monitoring a DIY solar water heating system. 1 DS18B20 (S=1) is placed in the collection tank (55 gal water), and the other is placed inside the waterhose to monitor the heat in the panel.

Sketch:

// Running DS temperature sensor(s) and relay(s) on one mysensor arduino node

Incoming change for sensor:2, New status: 1

As you can see, every once in a while S=1 reports the same value as S=0. I've tried to add a delay in the loop section, but without any luck. So now I'm stuck

Would this work with a 3,7V Li-Ion 18650 cell? Because I've got a S... load from old laptops

@hek said:

If you want to sleep the node, then using pin-interrrupt is a great way of waking the node when motion is detected.

You can use use the radio-irq pin for you sensors. It is currently not used by the mysensors library.

So, not need to wire the radio IRQ PIN at all?

Hausner

Ok, so basicly you are saying, that the PIR DOESN'T require an irq pin on the arduino?

Hausner

Hi,

I'm trying to make and sensor, as subject says. I've got temp (DS18B20) and actuator working, but not the PIR (HC-SR501).

PINs as follow:
RADIO IRQ = PIN2
Temp = PIN3
PIR data = PIN4
Actuator = PIN 5,6

My question is now, does a PIR require an Interrupt PIN on the arduino (PIN 2,3) , or can I use any PIN?

Hausner

No, serial monitor was just for testing. I would like to push it to mqtt.

I found the V_VOLTAGE and V_CURRENT, and the serial monotir showed up correctly as 38/39.

Hausner

Has anyone gotten a ASC712 to work with a actuator node?

I'm trying to monitor my diy solar panel, so that I can see what it is producing(if).

I've tried with the code below, but I can't get the node to send the readings to the gateway. I'm using a 30A ASC712 to do the readings. (Don't mind the motion sensor part).

My last code:

// Example sketch showing how to control physical relays. 
// This example will remember relay state even after power failure.

#include <MySensor.h>
#include <SPI.h>
const int analogIn = A0;
int mVperAmp = 66; // use 100 for 20A Module and 66 for 30A Module
int RawValue= 0;
int ACSoffset = 2500; 
double Voltage = 0;
double Amps = 0;
double Voltage_new = 0;
double Amps_new = 0;

#define RELAY_1 6  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
#define NUMBER_OF_RELAYS 2 // Total number of attached relays
#define RELAY_ON 1  // GPIO value to write to turn on attached relay
#define RELAY_OFF 0 // GPIO value to write to turn off attached relay

// Motion sensor defs
unsigned long SLEEP_TIME = 10000; // Sleep time between reports (in milliseconds)
#define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motionsensor.  (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
#define CHILD_ID 3   // Id of the sensor child
volatile int state = LOW;
boolean lockLow = true;
boolean lastTripped = 0;

MySensor gw;
MyMessage msgMotion(CHILD_ID, V_TRIPPED);
MyMessage msgvolt(4, V_VOLTAGE);
MyMessage msgcur(5, V_CURRENT);
MyMessage msg(CHILD_ID, V_LIGHT);

void setup()  
{   
  // Initialize library and add callback for incoming messages
  gw.begin(incomingMessage, AUTO, true);
  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Relay/Motion Sensor", "1.0");

  // Fetch relay status
  for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) {
    // Register all sensors to gw (they will be created as child devices)
    gw.present(sensor, S_LIGHT);
    // Then set relay pins in output mode
    pinMode(pin, OUTPUT);   
    // Set relay to last known state (using eeprom storage) 
    digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF);
  }
  
  pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as  input
  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID, S_MOTION);
  // attachInterrupt(DIGITAL_INPUT_SENSOR, ON, CHANGE);
  //delay(30000);
  gw.present(4, V_VOLTAGE);
  gw.present(5, V_CURRENT);
}


void loop() 
{
  // Alway process incoming messages whenever possible
  gw.process();

  //boolean tripped = (digitalRead(DIGITAL_INPUT_SENSOR) == HIGH);
  //  if (lastTripped != tripped ) {
//	gw.send(msgMotion.set(tripped?"1":"0")); // Send new state
//	lastTripped=tripped;
//   }
  
  //Serial.print("Raw Value = " ); // shows pre-scaled value 
  //Serial.print(RawValue);
  //gw.send(msgvolt);
  //Serial.print("\t mV = "); // shows the voltage measured 
  //Serial.print(Voltage,3); // the '3' after voltage allows you to display 3 digits after decimal point
  //Serial.print("\t Amps = "); // shows the voltage measured
  for ( int i=0; i<=20; i++ ){
    RawValue += analogRead(analogIn);
    delay(50);
  }
  Voltage = (RawValue / 1023.0) * 5000; // Gets you mV
  Amps = ((Voltage - ACSoffset) / mVperAmp);
  
  //gw.send(msgcur);
  Serial.print("mV = "); // shows the voltage measured
  Serial.println(Voltage);
  //Serial.println(Amps,3); // the '3' after voltage allows you to display 3 digits after             decimal point
  //delay(2500);
}
void incomingMessage(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
 if (message.type==V_LIGHT) {
 // Change relay state
 digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
 // Store state in eeprom
 gw.saveState(message.sensor, message.getBool());
 // Write some debug info
 Serial.print("Incoming change for sensor:");
 Serial.print(message.sensor);
 Serial.print(", New status: ");
 Serial.println(message.getBool());
 }
}

Any help would be appreciated

PS: Att HEK - why isn't there a "insert code" button, just like the "insert link" button?

Hausner

Turned out that the Nano was faulty.

I rebuilded the setup with a new Nano, and it's now working as designed
