Clone 2 skelets Relay and Button's

tomrask

I've tried to build together a relay and door sensor program from Hek one cloned program without success. I have a vera light. but I'm new about building sensors. Are there some who will look at the program and see where errors.

What I see in vera is only one door sensors and 2 relay, where there should have been 3 door sensor. I use a Nano with series connection to vera.

Hope some one can help me, last 3 weeks I have tried unsuccessfully various changes.

Hey Hek

Thanks for a really exciting home page , I really got interested in building a sensor myself just need some start help.

hek

First you present realys with id 1,2,3 and then you present switches with id 0,1,2. They overlap..

Hey Hek I changed the code, but it will not help. Now I get 3 door sensor and nothing else. hope you will help a little so that I understand the code. thank you

@tomrask
What Hek is trying to tell you is that you can't have 2 devices with the same number.

Change your first loop for:

  for (int sensor=0, 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);
  }

Change your second presentation loop for this

  for (int i = NUMBER_OF_RELAYS; i < (NUMBER_OF_RELAYS+NUMBER_OF_SWITCHES); i++)
  {
    gw.present(i, S_DOOR);
    delay(250);
  }

This way you are creating relays 0 and 1, and then switches 2, 3 and 4

Is there anyone out there who just want to give me a hand by getting this skeleton to work. I will be very happy just a little help. It could be great.

Vladut Grecu

Can you post the serial output of the Arduino?

@Vladut-Grecu

This is what I get from serial output

Vladut Grecu

There is something going on with you code. It tells your gateway that you only have 3 devices (0,1,2)

send: 1-1-0-0 s=0,c=0,t=0,pt=0,l=5,st=ok:1.4.1
send: 1-1-0-0 s=1,c=0,t=0,pt=0,l=5,st=ok:1.4.1
send: 1-1-0-0 s=2,c=0,t=0,pt=0,l=5,st=ok:1.4.1

I'll look into it when I get home, later this day.

From your serial output, I think that the problem is with vera.(config, etc.. I don`t use vera)
The node presents your devices and the gateway recognizes them correctly.

I guess you pressed the buttons to test them but when you press button nr 3 (child4) you got an error

send: 1-1-0-1 s=4,c=1,t=0,pt=2,l=2,st=fail:1
read: 1-0-1 s=4,c=1,t=0,pt=2,l=2:1

You either wrongly configured vera to use child 4 as something else rather than a button (and it doesn't expect for an update, even if you present it as a button and it says that is ok) or it's beyond my understanding.

I will kindly ask @hek to to take a look over what I said and verify the integrity of the code presented but before that, I'll try to do your setup and report back.

hek

I suggest you start simple. It is important you understand each step of the code.

Remove loops (present each sensor separately).
Remove debounce code (just read the digital inputs directly). They complicate things and you will better grasp what is happening without it.
Same goes for incoming messages. Look at the incoming message and try to understand what digital output (relay) you want to set,

I could probably write the code for you. But what is the point? If you manage it yourself you'll feel like superstar. Take it in small steps and ask more questions if you don't understand what the purpose a particular line has.

Hey Hek

Thank you for your good advice. I have a little vacation here in Easter. so I got it to work with 2 door sensors maybe it's not the best looking program . but it works .
Where can I learn more about these lines, I do not understand 100 % yet :

Bounce debouncer1 = Bounce();

debouncer1.attach(BUTTON_PIN1);

digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);

Thanks for the help .

@tomrask when you set the relays to the " last known state" the same value (1) is used for all the relays.
