Sending Variables to a arduino switch

mfalkvidd

What is the output on the serial port when you run it?
What type of led are you using?

Most leds cannot be controlled by voltage level (analogWrite), they need to be controlled by pwm.

patrick schaerer

The LED is not the problem. AnalogWrite works perfect.
Serial out is:

IncomingMessage routine is never executed

Im having this issue as well with domoticz... sometimes i get a reply but its like that ack doesnt work somewhere. Im trying to figure this out but no luck so far. Was just about to post in Domoticz forum yesterday but didnt...

Im trying to recieve a VAR1 for my rain sensor... sometimes it takes 10 tries and sometimes it never returns. I have the sensor just beside the gateway with no luck so my feeling is that there is an error in the code somewhere (Domoticz or Mysensors, dont know).

So far I have not debugge my gateway (no logs) but in MYSController i get the request in but never see any reply out with the VAR1 value.

@patrick-schaerer the problem in your code snipped is the delay(1000).

This is a blocking call which blocks also your radio module from communicating. You have to use gw.wait(1000); i.s.o. delay. Now your plugin will receive data.

ok Ill try that

sundberg84

I don't have any delay in my code. Still same problem with var1 and domoticz.

patrick schaerer

delay is not the problem ... i changed the code to gw.wait(1000)
Serial output is the same

sundberg84

I wrote a code that only fetch time and the V_VAR1 - works every time.
MySensors 2.0b, Ethernet GW, Domoticz latest version:

#NOTE THAT CODE IS FOR MySensors > 1.6.0b version
#define MY_DEBUG 

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

#define MY_NODE_ID 7

#include <SPI.h>
#include <MySensor.h>  
#include <Time.h>  

boolean timeReceived = false;
unsigned long lastUpdate=0, lastRequest=0;
#define CHILD_ID 1   

boolean pcReceived = false; 
unsigned long lastSend =0; 

void setup()  
{  
}

void presentation()  {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("Test to get V_VAR1", "1.0");
}

void loop()     
{     
  unsigned long now = millis();

  // If no time has been received yet, request it every 5 second from controller
  // When time has been received, request update every hour
  if ((!timeReceived && (now-lastRequest) > (5UL*1000UL))
    || (timeReceived && (now-lastRequest) > (60UL*1000UL*60UL))) {
    requestTime();  
    lastRequest = now;
  }

    //Request V_VAR1 every 5 sec if not recieved.
    if (!pcReceived && (now - lastSend > 5000)) {      
      request(CHILD_ID, V_VAR1);
      lastSend=now;
      return;
    }
    if (!pcReceived) {
      return;
    }
}

void receive(const MyMessage &message) {
  if (message.type==V_VAR1) {
  Serial.print("Received last pulse count from gw:");
  Serial.println(message.getULong());
  pcReceived = true;
  }
}

// This is called when a new time value was received
void receiveTime(unsigned long time) {
  // Ok, set incoming time 
  setTime(time);
  Serial.print("Got time, hour: ");
  Serial.println(hour());
  timeReceived = true;
}

Its not different from my Rain sensor code... where i have the same problem as above... so there must be something else blocking recieve function in that code or radiotraffic... Its nothing wrong with Domoticz and/or Gateway what i can see... its something wrong with the code in the sensor itself. To be continued...

sundberg84

What is similar in our sketches that does not work is that we use pin 3. I have seen some post with relays that it worked if you move to pin 4. Don't know why but I will try this tonight. Worth a shot...

@patrick-schaerer and @sundberg84

I've compiled your code and uploaded in my Arduino to debug your issue. What i noticed is that the sketch worked on my side, two remarks on the code snipped:

why switching back to 9600 baud and not just setting your terminal to 115200 baud.
line 83 contains an error i think the + should be removed so it becomes this line:

LED_Level = gwLEDLevel;

But this will not solve you original problem. What i also noticed is when you requesting data from a none exiting node you do not get any data but the following error in your Vera controller log file:

Open a terminal like putty -> new connection to your Vera's IP address login with username root and the WIFI password and give this command

tail -f /var/log/cmh/LuaUPnP.log

The error line you might see is this one (the second line is yellow marked)

50      01/17/16 15:07:28.915   luup_log:64: Arduino: Log: read: 50-50-0 s=255,c=3,t=12,pt=0,l=3,sg=0:0.2 <0x6011>
02      01/17/16 15:07:28.918   luup_log:64: Arduino: Incoming internal command '50;255;3;0;12;0.2' discarded for child: nil <0x6011>

So it might help to:

start MySensors inclusion mode
give a reset on your Arduino
wait to see MySensors does find new nodes
press stop inclusion
wait until Vera is ready again
press reload
wait until Vera is ready again
reset your Arduino again and make sure the MySensor node shows the corrent version information

sundberg84

Tried my hypothesis above but same error. What made some different now was to add a second cap of 10uF to the radio... still nog good, but at least after some tries I now receive the V_VAR1.

@sundberg84
Can your code be used on 1.5.1 ??
I need to get Temp Values from Vera. to my PID controller

sundberg84

No - code is > 1.6b
@clio75 I couldnt find out what my problem was... got tired of it and uploaded same sketch so complete new set of hardware... and now its working so my occlusion was bad hardware.

clio75

@sundberg84
Thanx for your reply,

Do you know where I can find one example for getting variables from Vera ?
I have tried searching, but can't seem to find any :(
Thanx

sundberg84

In the library you can use timeawaresensor to recieve time
https://github.com/mysensors/Arduino/tree/development/libraries/MySensors/examples/TimeAwareSensor

The raingauge, WaterMeterPulseSensor and Power meter to recieve V_VAR1

patrick schaerer

@BartE: Thank you for your corrections to the code. I changed that.

Now the sketch works. All I did is to add a new repeaternode between the gateway and the receiving node. It was definetly a hardware problem (or the problem was solved in 1.5.3 update).

The LED_Node_var sketch works!

Nuubi

Eh, how do you define or set a value for, let's say, V_VAR1 in Vera?

patrick schaerer

in the advanced tab all the way down at the bottom there are should be Variable1. Put a value in the field and save.
the next time your device requests the variable, the new value will be sent.

Thanks, though so, too.
So the next question is, is it possible to add variables to sensor types that don't have those to begin with? In my case I'd like to add few variables to window covers (S_COVER in http://www.mysensors.org/download/serial_api_15). Can't test now, but would this gw.present(CHILD_ID_OF_BLINDS, V_VAR1) work in adding this property to the blinds?

patrick schaerer

It should work. The variable1 appears in vera after the sensor had requested var1. (But Im not completely shure about that ... )
