Hello,

I'm living in Belgium, so I will stay at home :(

Hello everybody.

I would like to know if it was possible to improve the resolution for the DS18B20 sensors.

The goal is to have a reading of XX.XX degrees instead of XX.X.

In the DallasTemperature.CPP, i have seen "DallasTemperature::setResolution", but i don't know how to use it in the sketch, certainly in the setup(), i think.

Thanks for answers

Hello, have you a message on the serial print ? Failed reading humidity from DHT or the value ?

If you want to send every 2 mns, you have to "sleep" 2601000 milllseconds - the processing time for your code (near 0 compared to 2 mns)

@klim Nice integration.

Do you have a schematic of your board ?
especially for the pins with the jumper.

As I can see, the blue jumper is for open/closed current loop, but for the other pins ?

Thanks

@pjeterinfo Hello, maybe here [remove debug]](http://www.mysensors.org/build/debug)

Hello,

I saw on the freedomotic page, it was possible to use the serial gateway with freedomotic, but also a MQTT Broker.

Has anybody used this framework with the MQTT gateway with success ?

Thanks

@tekka Ah OK, it's better to know it, thanks; ;)

And I found the error this morning and it works great......

To create the configuration file for openHAB, I made a copy/paste of the Mysensors example., and I haven't seen it was a space character at the beginning of each lines.

I removed it, and it's working fine.now

So be carefull with the spaces, it was a stupid mistake and boring to find.

I have done this test 5 times, so I'm sure that it's the problem.

Thank you everybody....

And tonight, the weird is back

C:\Users\Totche>netstat -an|find "1883"
  TCP    0.0.0.0:1883           0.0.0.0:0              LISTENING

In openHAB.fx, I can see the msgs from the node, so I suppose that the ethernet connection is working

With MYSController, nothing displayed, no node network

With the serial, I can see the exchanges between node and the MQTTgateway

So what's wrong ? The Gateway, a port redirection ????

@GuyP Now I can see that

C:\Users\Totche>netstat -an|find "1883"
  TCP    192.168.1.13:25638     192.168.1.134:1883     ESTABLISHED
  UDP    0.0.0.0:61883          *:*

The last Ip 192.168.1.234 was out of range with the router definitions

But no more values in openHAB, pfff

@Xander I have that

C:\Users\Totche>netstat -an|find "1883"
  TCP    0.0.0.0:1883           0.0.0
  UDP    10.10.10.170:61883    

:

@GuyP Thanks for reply

I'm using windows 7, so I can't use your command, and see if connection is made

The IP in openHAB is set since the beginning, and I never changed.

@Xander Thanks ;)

Very great link, now I can see what is sent.

1)-

2- The ip in MQTT.fx is the same as in openhab.cfg

mqtt:mysensor.url=tcp://192.168.1.234:1883
 mqtt:mysensor.clientId=MQTT

3- test.items

Group all
Group meteo //(all)
Group noeud_1  (meteo)
Group noeud_2  (meteo)
//Group sketch (all)

Number noeud1_temperature  "Temperature [%.1f °C]"    (noeud_1, all)  {mqtt="<[mysensor:MyMQTT/21/0/V_TEMP:state:default]"}

Number noeud1_humidite     "Humidite [%.0f Rh]"     (noeud_1, all)  {mqtt="<[mysensor:MyMQTT/21/2/V_HUM:state:default]"}

4- openHAB runtime

And finally...........................

nothing :(

PS : i don't see the repeater with the barometer, I need to dissociate them so one nano more :(

Re,

I tried to use MYSController without success

The IP is 192.168.1.234:1883 for the MQTT controller , but I can't read any values with the browser and MYSController.
And as you can see in the serial monitors, the nodes seem to discuss together.

I don't know how to check the communication with the MQTT gateway, apparently the problem comes from him
Any tips, ?

Thanks

@Gutz2001 Instructables maybe it can help

@Xander Thanks for the answer

For now, I have a MQTT controller, one repeater node with a BMP180 sensor (to do the forecast on a long time, as by definition the repeater never sleeps, with a modified sketch and a timer of 1 seconde), and an another node with temperature, luminance and hymidity sensors.

After some readings , i think that the gateway doesn't provide the Id, it's the role of the controller

=> in this discussion, you can read that, it's for Vera controller

Your going to want a controller in the long term. For testing you can either hard code the node ID in the sketch (you will want to flash the EEPROM clear sketch when you get a controller)

The reason your not seeing the temp on the gateway is because it doesn't get sent if there is no node ID.

Basically the node is asking the gateway/controller who am I and the controller isn't responding so it just keeps asking.

=> I use openHAb instead of Vera, and there is XXX.items file where you define the Ids for node and child

Number node1_temp  "Temp [%.1f °C]"     (node1,all)  {mqtt="<[mysensor:MyMQTT/20/10/V_TEMP:state:default]"}
Number node1_humid "Humid [%.1f %%Rh]" (node1,all)  {mqtt="<[mysensor:MyMQTT/20/11/V_HUM:state:default]"}

So I think that in this case, if the Ids are "constants" in openhab, they can't be randomly dealed by the gateway, and have to be fixed in each node

I just tested by giving Id to the nodes, and all seems correct

MQTT gateway

I use this one => Adafruit

#include <DHT.h>

#define HYGRO_PIN 4         // Pin DHT11

DHT dht(HYGRO_PIN, HYGRO_TYPE);

float hygrometrie_mem; 
float hygro_temp_mem;  

// hygrometrie
MyMessage msg_hygro(HYGROMETRIE_CHILD, V_HUM);

 float hygro_temp = dht.readTemperature();
 float hygrometrie = dht.readHumidity();
 // isnan => Is Not A Number
 if (isnan(hygro_temp) || isnan(hygrometrie))
 {
    Serial.println("Echec lecture du DHT");
 } 
 else if (hygro_temp != hygro_temp_mem) 
 {
   hygro_temp_mem = hygro_temp;
 }

  Serial.print("Temperature hygro : ");
  Serial.print(hygro_temp);
  Serial.println('C');
  if (hygrometrie != hygrometrie_mem) 
  {
    hygrometrie_mem = hygrometrie;
    gw.send(msg_hygro.set(hygrometrie, 1));
    Serial.print("Hygrometrie : ");
    Serial.print(hygrometrie);
    Serial.println('%');
  }

So back to serial gateway.

Are you sure that the gateway gives the Id ?
Ethernet, MQTT and serial gateways never send back ids to the nodes in my case.

When I force the Id, it's working and the gateway "shows" the values

@Xander Thanks for the answer.

For the auto-dealing with Ids, who did it ? Openhab or the gateway ?, or are the Ids fixed with (mysensor:MyMQTT/20/10/) ?

Thanks
