Strange value being sent from controller using mixed temp/relay node

Gambituk

Hello, I am getting strange values being sent from this controller sketch from @gadu (many thanks again) and this node sketch from @pgo

It almost works.. i am going via mosquitto install on the same raspberry as openhab, and it does turn on and off the relay while sending temp values from the same node. The problem i am having is that it is not reliable, it doesn't always turn on and off, and i have found that the following is being sent from the mqtt gateway sketch:

0;0;3;0;9;send: 0-0-21-21 s=0,c=1,t=0,pt=0,l=5,st=ok:19.7r

so.. node 21 is just sending temp values, node 24 is the mixed temp/relay..

As you may notice the 1 and zero code for the relay is getting mixed with the last received temp values, which seems to be ok if the last temp read is more than 10degrees resulting in a 1.xx value sent or a 0.xx value sent, which is accepted as a 1 or 0, but when it receives a value below 10 then it converts it to something like 047 or 147 which doesn't trigger the relay correctly! Please any help or guidance to understand where the 1 or 0 message is coming from?

I imagine its what is being sent from the gateway sketch that is mixing the payload, but i cannot see how to reformulate what is sent to send only a 1 or 0 when sending to the relay...... ??

I guess this probably should have been in troubleshooting :S

gadu

Just guessing here, have you different child id's on the temp and relay?

Gambituk

No it seems like they are given the same child id's. Ok, so maybe i'l look at how to force a different child id for each sensor/actuator

BulldogLowell

the combining of the extensible sketches make it harder than needs to be.

How many sensors are you connecting of each type?

Gambituk

Hi, i have 3 temp sensors and 2 relays, I am just looking at how to make this work but am not making much progress. Cant figure out how to assign the child id's. Any help would be appreciated.

Gambituk

was thinking of presenting the temps sensors first, and adding something like && i>NUMBER_OF_RELAYS to start assigining child id's above the range of relays? Will test and report back

Gambituk

I tried to modify the temp child presentation like this..... but it seemed to have no effect

int offsetforrelays=5;   //(at start of sketch)

// and this further down in the presentation for temp sensors


 for (int i=0; i<(numSensors+offsetforrelays) && i<(MAX_ATTACHED_DS18B20+offsetforrelays) && i>offsetforrelays; i++) {   
     gw.present(i, V_TEMP);
  }

but so far it hasn't assigned any different id's to the temp sensors. Anyone got any pointers?

BulldogLowell

@Gambituk said:

#include <OneWire.h>presen

#include <OneWire.h>presen

do you still have this typo in your code?

Gambituk

no, i took it out (without effect) about an hour ago

BulldogLowell

@Gambituk

try something like this:

#define NUMBER_OF_TEMP_SENSORS 3

void setup()  
{ 
  sensors.begin();
  gw.begin(incomingMessage, AUTO, true);
  gw.sendSketchInfo("Temp and Relays", "1.0");
  for (int i=0; i < NUMBER_OF_TEMP_SENSORS ; i++) 
  {   
    gw.present(i, V_TEMP); // creates 0, 1 and 2
  }
  for (int sensor=1, pin=RELAY_1 ; sensor <= NUMBER_OF_RELAYS ; sensor++ , pin++) 
  {
    gw.present(NUMBER_OF_TEMP_SENSORS + sensor, S_LIGHT); // should create 3 and 4
    pinMode(pin, OUTPUT);   
    digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF);
  }
}

you will also have to sort out the sensor numbers in the callback

So far it seems to create 0,1,2,4,5 but i think that's not going to be a problem, just working my way through to figure what else i need to change for the callback? (and what a callback is :D )

Thanks for the help so far!

BulldogLowell

@Gambituk said:

the call back function:

incomingMessage()

look to get this right:

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

so that the command matches the sensor numbers...

Gambituk

@BulldogLowell

for (int sensor=1, pin=RELAY_1 ; sensor <= NUMBER_OF_RELAYS ; sensor++ , pin++)
{
gw.present(NUMBER_OF_TEMP_SENSORS + sensor, S_LIGHT); // should create 3 and 4

For the earlier part, should this be "for (int sensor=0" to get 3 and 4?

I get 4 and 5 ... But either way, i dont suppose it matters that there is a gap of 1 in the sensor child id's.

I change the callback to this:

digitalWrite(message.sensor - 4 + RELAY_1, message.getBool() ? RELAY_ON : RELAY_OFF);

and that works.... i can send a message and it activates the relay.. :D

BUT.... :(

Here i am sending a message with 1 and then 0 to relay id4 and then the same to relay id5 -It works, but i still have the 1.3 and 0.3 values

    read: 0-0-25 s=5,c=1,t=2,pt=0,l=4:1.3r

    Incoming change for sensor:5
    
    Incoming change for sensor:5, New status: 0

And then it starts going even crazier, only seeing the status as 1 and received command is nothing like boolean so it see's 0's and 1's as only 1's

    read: 0-0-25 s=4,c=1,t=2,pt=0,l=4:113r
    Incoming change for sensor:4
    
    Incoming change for sensor:4, New status: 1
    
    read: 0-0-25 s=4,c=1,t=2,pt=0,l=4:013r
    Incoming change for sensor:4
    
    Incoming change for sensor:4, New status: 1

So i am thinking it is still a problem with what is sent from gateway somehow... :(

Any ideas

@BulldogLowell I just tried uploading a standard vanilla relay node, and i get the same garbled data instead of 1 and 0 (should have tried this at the start, but i am happy with what i have learned in the last 12 hours.) So it seems almost certain that it is an issue with the @gadu version of the mqtt gateway.. which is unaltered from the above post. #2 above

Interesting findings, if you find any solution for this in the MQTT gateway I would really appreciate if you post it. I'm about to start implementing relays as well.

(it's actually not my version, I think @ntruchsess is the one who created it) ;)
