Combining relay and temperature sketch

[gohan]

try to put a wait(500) at end of loop function, or even wait(1000)

@gohan said in Combining relay and temperature sketch:

wait(1000)

Oh.. like I said : something stupid..

Thanks a lot. :-)

I also had "#define MY_NODE_ID 7", because I couldn't see the relay on my Vera.

[gohan]

DHT sensor doesn't like to work very quickly, it needs some resting time between measurements :D

[Tim76]

@gohan modfied my code..... still the same.... I get 16 children (relays) and no temp...... I have 4 ds18b20's connected.....
And I get the error switch command on the relays....😑😑

Ok, now I have another problem.

When I build the relay/dht node, I first made the thing work with the relay with button actuator sketch alone (the DHT was plugged, but it was an additional feature I wanted to add).

Now, it seems that my power source doesn't have enough power to make the relay to close. The led on my relay board blinks when the relay is on and off, but nothing.

That's weird.. I'll try running the relay sketch alone, just to see.

[gohan]

@Tim76 ok, let's go back to the beginning. Try with one sensors only, if everything works then add one relay, then add the second and keep adding the sensors until you see something wrong. You need to go step by step, otherwise with all that stuff you have it will be impossible to debug.

[Tim76]

@gohan ok

[Tim76]

@gohan both sketches work perfectly stand alone.... but I think the problem lies within the assingment of the child id's...
James Bruce talks about this "bug" in his video on how to combine sketches.....
They relay sketch assigns from 1 to 16
And the temp sketch assigns from 0 to 15
So they both try to use the same id's for their children when you try to combine them....
I need a way to get around that and have relays on 1-16 and temp on 17 to 32......
Or there might just be the same "bug" in the temperature sketch.....😬😬 wich might mean that they can't be combined for now......😒😒

[gohan]

if use something like this in presentation?

for (int i=1; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i+3, S_TEMP);

you get the idea, just shift the child id of the dallas sensors and leave the first 4-5 IDs for relays

[Tim76]

@gohan aha! Will be trying that later tonight..... I'll keep you posted! 😊 Thx man!

[Tim76]

@gohan soooooo...... I tried this:

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=1; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i+16, S_TEMP);
  }
  for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
    // Then set relay pins in output mode
    pinMode(pin, OUTPUT);
    // Set relay to last known state (using eeprom storage)
    digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF);
  }
}

now I get the temp sensors with child id's 1 to 16 and no relays at all

[gohan]

I probably used wrong sintax

[Tim76]

@gohan tried this again...... same result.....

  // Fetch the number of attached temperature sensors  
  numSensors = sensors.getDeviceCount();

  // Present all sensors to controller
  for (int i=17; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i, S_TEMP);
  }
  for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
    // Then set relay pins in output mode
    pinMode(pin, OUTPUT);
    // Set relay to last known state (using eeprom storage)
    digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF);
  }
}

@Tim76 you forgot to present the relays.... :sweat:

[Tim76]

@gohan no I didn't...

  // Present all sensors to controller
  for (int i=17; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i, S_TEMP);
  }
  for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
    // Then set relay pins in output mode
    pinMode(pin, OUTPUT);
    // Set relay to last known state (using eeprom storage)
    digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF);
  }
}```

[Tim76]

@gohan seems like it's early for both of us.....;-)

[gohan]

you only have present(i, S_TEMP) but you also need to add present(sensor, S_BINARY) in the relay section otherwise you will not present any relay at all.

[Tim76]

@gohan 😳😳😳 seems like it's only early for one of us...... I,ll change it later today.....
