How to go from sketch to api

[wadesready]

Greg...first I want to say thanks for the GREAT plugin. Opened up my homeseer world to a whole new level. I do have some trouble however going from a sketch found on the web to implementing into an api sketch. It would be great if there was a "how to" tutorial to take a sketch off the web and cut/paste the parts into the api and "at least get close" to making it work. maybe what I am wanting is not possible?

What do you want to do?

The problem is you might need different bits depending on what you want to do. I am not sure how to write this up. If you post what you want I am sure we can point you in the correct direction.

Here is an example that I am planning on soon. This is an example sketch for a flame sensor and I want to have one for each stove top burner. I would prefer nodemcu. If I had to use a Uno then I would hope to get all three flame sensors into the arduino. so which parts to I cut and paste into the api Greg?

int flamePin = A0; // flame sensor sensor input

int ledPin = 13; // select the pin for the LED

int flameValue = 0; // variable to store the value coming from the photocell val

//unsigned long interval=1000; // the time we need to wait

//unsigned long previousMillis=0; // millis() returns an unsigned long.

void setup() {

Serial.begin(9600);

pinMode(ledPin, OUTPUT);

digitalWrite(ledPin, LOW);

}

void loop() {

// read the value from the flame sensor:

flameValue = analogRead(flamePin);

flameValue = constrain(flameValue, 0, 1023); //adjust depending on environment.

Serial.println(flameValue); //print our value

//prevents entire program from slowing down /w a ' delay() '

//allows continous readings consistent speed even with conditions

//if ((unsigned long)(millis() - previousMillis) >= interval) {

//previousMillis = millis();

if(flameValue > 700){ // if the flame reading is greater than 300,alert with buzzer and LED

digitalWrite(ledPin, !digitalRead(ledPin)); //turn led on

}

else if (flameValue < 700){

digitalWrite(ledPin, LOW);//turn led off

}

// }

}

This is quite an easy one to start with.
1. You need all the variables set up and placed where it says "Declare your variables here"
2. In the void HSSetup you need to set up the led pin (I guess you still want the LED?) We do not need the Serial data as we are sending the data to HS now.
3. in void HSloop under /*Execute regardless of connection status*/ we put the code to control the LED so there is always indication even if not connected to HS.
4. In void HSloop under /*Execute ONLY when HomeSeer is connected*/ we send the data to HS using the SendToHS function. There is also the code for a delay in there so the data is not sent to HS on every loop.

so you should end up with something like this:

//**************Declare your variables here*******************

int flamePin = A0; // flame sensor sensor input
int ledPin = 13; // select the pin for the LED
int flameValue = 0; // variable to store the value coming from the photocell val
unsigned long interval=10000; // the time we need to wait
unsigned long previousMillis=0; // millis() returns an unsigned long.


//****************************************************************

void HSSetup() {

pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);

}


void HSloop() {



  //************************
  //Add YOUR CODE HERE;
  //************************
  /*Execute regardless of connection status*/
flameValue = analogRead(flamePin);
flameValue = constrain(flameValue, 0, 1023); //adjust depending on environment.

if(flameValue > 700){ // if the flame reading is greater than 300,alert with buzzer and LED
digitalWrite(ledPin, !digitalRead(ledPin)); //turn led on
}
else if (flameValue < 700){
digitalWrite(ledPin, LOW);//turn led off
}


    /*Execute ONLY when HomeSeer is connected*/
  if (IsConnected == true) {


//prevents entire program from slowing down with a ' delay() '
//allows continous readings consistent speed even with conditions
if ((unsigned long)(millis() - previousMillis) >= interval) {
previousMillis = millis();

SendToHS(1,flameValue);

  }

}
}

Thanks Greg! I have so much to learn about arduino, but the possibilities are endless.,..

[wadesready]

what about one like this Greg? do I delete the Serial.print and Serial.printin?



// defines pins numbers
const int trigPin = 2; //D4
const int echoPin = 0; //D3

// defines variables
long duration;
int distance;

void setup() {
pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
Serial.begin(9600); // Starts the serial communication
}

void loop() {
// Clears the trigPin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);

// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);

// Reads the echoPin, returns the sound wave travel time in microseconds
duration = pulseIn(echoPin, HIGH);

// Calculating the distance
distance= duration*0.034/2;
// Prints the distance on the Serial Monitor
Serial.print("Distance: ");
Serial.println(distance);
delay(2000);
}

Yes, you need to remove the Serial.print and add a SendToHS(1,distance). as this is the value you want to see in HS. The only problem with this one is it uses Delay and this will stop the Arduino communicating. You need to replace all the Delays with something like what you had in the first sketch. See https://www.makeuseof.com/tag/arduin...-shouldnt-use/

Thank you Greg for your help!

[wadesready]

I need some help Greg...yet again... Not too sure about which/what serial.prints I should be deleting and what to be sending to hs. Does it do any harm to leave them?

I'm connected to hs. I have pin2 as an input in the plugin. opening a screen in the arduino IDE I can see which pin is touched, but I am getting nothing to change in the plugin on hs.

HI Mate

You probably should read the documentation and read the comments in the plugin. That will give you lots of guidance.....The serial prints send data out the arduino serial port, great for debugging however simply not needed as we are not using the serial port on the arduino.

SendToHS(1,distance) this is where all the magic happens, its the routine that sends the value to Homeseer.....Have you defined this in your homeseer plugin as a device ?
