@Mark-Swift same issue here

@Mark-Swift check this for node-to-node communication http://forum.mysensors.org/topic/3467/basic-setup-network/2 as @hek said setup a database in nodered to save the values received from node-1 and you could request that from node-2

this is my node to node program:

// Enable debug prints
#define MY_DEBUG
#define SWITCH_PIN 2
// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69
boolean state=false;
#include <SPI.h>
#include <MySensor.h>  
#define MY_NODE_ID 10
#define CHILD_ID_SWITCH 1 

MyMessage switchMsg(CHILD_ID_SWITCH, V_LIGHT);

void setup()
{
  pinMode(SWITCH_PIN,INPUT_PULLUP);
}

void loop()
{
  if(digitalRead(SWITCH_PIN)==LOW)
  {
    delay(100);
    if(digitalRead(SWITCH_PIN)==HIGH);
    {
      state=!state;
      if(state)
      {
        send(switchMsg.setDestination(2).set(49));
      }
      else
      {
        send(switchMsg.setDestination(2).set(0));
      }
    }
  }
}

• destination node id is 2
• destination of type light variable

@hek Adafruit's MQTT libarary doesnt have wildcard subscriptions switching to https://github.com/256dpi/arduino-mqtt SSL seems to be working and library has callback support

@hek i am trying to do that in void loop{} will update once it gets working properly and will do a pull request, the problem is that i can subscribe to a main topic but not its subfeeds

@hek I somewhat succesfully integrated Adafruit MQTT library into MySensors, i am able to sent out data but not able to receive (subscribe). These are the changes i made:

Any help would be really appreciated???

@tomkxy there's an android app named wifi analyser and use that to check the crowded wifi channels and set the rf24 channel to the least crowded one.... wish i had an SDR for more hacking and learning

@Oitzu Thank for your replies, but i have already read that blog earlier and my other PA+LNA modules connected to the nodes just work fine.

@Oitzu I tried adding capacitors and the issue still persists, I will try another supply

@hek i tried even using #define MY_RF24_PA_LEVEL RF24_PA_MIN with the PA+LNA modules but still sending fails but receiving is ok, i think its an issue with NodeMCU and PA+LNA modules rather than power supply issues.

Same issue here, all data transmitted fails with st=fail , i thought it was a power issue and specific to me, @hek

@hek pubsubclient has issues with ssl connection, frequent disconnections. Adafruit's MQTT library works like charm, trying to integrate into MySensors

@hek I didnt know there was an optional method. Thanks

finally succeeded in implementing ssl for MQTT with esp8266!!!!!!! will post in Development...... http://forum.mysensors.org/topic/3385/ssl-support-for-mqtt-on-esp8266

@hek @Anticimex First install https://github.com/esp8266/arduino-esp8266fs-plugin and upload the crt file to the ESP8266 file system.

then issue these command from the folder in which MySensors is installed:
sed -i 's/WiFiClient/WiFiClientSecure/g' Arduino/libraries/MySensors/core/MyGatewayTransportEthernet.cpp

sed -i 's/WiFiClient/WiFiClientSecure/g' Arduino/libraries/MySensors/core/MyGatewayTransportMQTTClient.cpp

change your GatewayESP8266MQTTClient to this:

NB: i used https://github.com/owntracks/tools/raw/master/TLS/generate-CA.sh for generating the ca files

you just have to change WiFiClient client; to WiFiClientSecure client;

Already work in progress, esp8266 2.1.0 library added support for having ca certificates in SPIFFS memory, not enough documentation on using it....
https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/src/WiFiClientSecure.h#L52-L66

Thanks for the fast replies. This is the only forum i have seen with the fastest replies. @hek @Anticimex there really exist an mqtt library for esp8266 supporting SSL, any way to change to this: https://github.com/tuanpmt/esp_mqtt

Thanks for the reply but the controller already supports ssl, its the mysensors eso8266mqtt client that doesnt support ssl!!!

@hek @Anticimex is there any way to add SSL support for MQTT client on nodemcu(esp8266). I know that esp8266 supports SSL(from node-mcu custom builds http://nodemcu-build.com/). I am using domoticz as controller and it already has MQTT SSL support. I am planning to run domoticz on my VPS so SSL support for MQTT is required.

I had the same problem after updating to 2.1.0. I was getting wdt reset error, @Admin @hek could you please look into the issue???

Maybe the gateway does not seem to be recognized by the router is that because the MAC address is not a valid one of the static IP you defined in the program does not match your router's subnet

@Anticimex sorry for the interruption, i was using rsync to get eveything synced and i might have messed something uop, sha204 library was missing from my libraries folder, now everything works, thanks for the prompt and fast support.

@Anticimex no, I'm using the sketch from the examples.....
am i missing some libraries????

@Anticimex development branch

@Anticimex said:

@noelgeorgi AES encryption is already supported for both NRF24 and RFM69 radios. See MyConfig.h on the development branch for the flag to use. Doyxgen documentation I link to in this thread on the topic post also contain the personalization instructions for encryption on the development branch.

Thanks for the info.
I'm getting the following errors when compiling securitypersonalizer:

  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.

doesnt the ATSHA204 library has ATSHA204.h

@Anticimex @hek is it possible to encrypt the data sent over nrf modules using this https://github.com/DavyLandman/AESLib ???

@hek thanks for the reply, I will use node-red to convert mqtt messages to json for Domoticz, it does have authentication

@Admin @hek could you please take a look at this http://forum.arduino.cc/index.php?topic=101104.0, even though the sketch consumes a lot of program space, an arduino mega is sufficient for the task!!

I could not find any option for password authentication or any type of authentication on mysensors gateway on port 5003, anyone on the LAN could access or sent data to the gateway.... any help would be appreciated...
