Thanks - that's what I needed to point me in the right direction. Issue is resolved now

Ok, figured it out and got the gateway working. The issue is with the RFM69 and the Wiznet Ethernet shield you cannot use pin 10 for the cs on the RFM69. I used pin 7 since I don't use the LED's.
Add the following to your MyConfig.h
#define RF69_SPI_CS 7

and everything should work. Onwards to building the sensors now!

The Ethernet gateway was just too unstable for me and I couldn't get any inclusions. I switched it for a serial gateway and its all working great now. I have a single sensor that is sending data to my House Assistant install.

I have a sensor working - humidity/temp. Very basic. Trying to add a second of the exact same type.

In my sketch, I've tried to manually add:
#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define NODE_ADDRESS 2
and
gw.sendSketchInfo("SecondLvl", "2.0");

I already have a node 1 and it doesn't seem to be taking my node_address? I tried deleting the json file in Home Assistant, restart, add sensor 1. Everything works... try to add the second one and it gets named 1 as well?!

The Ethernet gateway was just too unstable for me and I couldn't get any inclusions. I switched it for a serial gateway and its all working great now. I have a single sensor that is sending data to my House Assistant install.

Ok, my newbie is showing. I have home assistant configured just didn't know I had to have it connected before it would work. Will try that.

Well... almost. Things are talking but not quite. The gateway never seems to send a ID to the sensor node?

On the sensor node:
ensor started, id=255, parent=0, distance=1
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
req id

On the Gateway Node:
0;0;3;0;5;1
0;0;3;0;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0,sg=0:
255;255;3;0;3;

255;255;3;0;3;

So it looks to be sending a request, but the gateway isn't returning an id. The sensor node is a humidity node, exactly as provided in the example, other then adding: MyTransportRFM69 transport;

Ok, figured it out and got the gateway working. The issue is with the RFM69 and the Wiznet Ethernet shield you cannot use pin 10 for the cs on the RFM69. I used pin 7 since I don't use the LED's.
Add the following to your MyConfig.h
#define RF69_SPI_CS 7

and everything should work. Onwards to building the sensors now!

I have partial success getting my RFM69 radios working. I had to make the following changes:
MySensor.h

Change: #include "MyTransportNRF24.h" to #include "MyTransportRFM69.h"
Change line 158 from
MySensor(MyTransport &radio =*new MyTransportNRF24(), MyHw &hw=*new MyHwDriver()
to
MySensor(MyTransport &radio =*new MyTransportRFM69(), MyHw &hw=*new MyHwDriver()

Sensor side I get:
sensor started, id=255, parent=0, distance=1
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
T: 28.00
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
H: 33.00
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
T: 29.00
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
T: 28.00
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
H: 32.00

While Gateway side I get:
0;0;3;0;9;gateway started, id=0, parent=0, distance=0
0;0;3;0;9;read and forward: 255-255-255 s=255,c=3,t=7,pt=0,l=0,sg=0:

0;0;3;0;9;send: 0-0-255-255 s=255,c=3,t=8,pt=1,l=1,sg=0,st=bc:0
0;0;3;0;5;1
0;0;3;0;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0,sg=0:
255;255;3;0;3;

I'm not sure what the st=fail means in the sensor debug?

Also I still do not have the gateway listening on port 5003. Still trying to decipher that. I wanted to try and isolate the fault and make sure the radio part was working.

My gateway sketch:
0_1466189155349_MyEthernetGateway.ino

I also make changes to the following files:

MyConfig.h:
#define DEBUG

/**********************************

• RFM69 Driver Defaults
  ***********************************/
  // Default network id. Use the same for all nodes that will talk to each other
  #define RFM69_NETWORKID 100

// Default frequency to use. This must match the hardware version of the RFM69 radio (uncomment one):
// #define RFM69_FREQUENCY RF69_433MHZ
//#define RFM69_FREQUENCY RF69_868MHZ
#define RFM69_FREQUENCY RF69_915MHZ

// Enable this for encryption of packets
//#define RFM69_ENABLE_ENCRYPTION
#define RFM69_ENCRYPTKEY "sampleEncryptKey" //exactly the same 16 characters/bytes on all nodes!

The line for the 915Mhz only called it FREQUENCY so changed it to match the entries above it, assuming it is correct.

MyTransportRFM69.h:
class MyTransportRFM69 : public MyTransport
{
public:
MyTransportRFM69(uint8_t freqBand=RFM69_FREQUENCY, uint8_t networkId=RFM69_NETWORKID, uint8_t slaveSelectPin=RF69_SPI_CS, uint8_t interruptPin=RF69_IRQ_PIN, bool isRFM69HW=true, uint8_t interruptNum=RF69_IRQ_NUM);

This change was to identify my radio as an RFM69HW.

Good suggestion but yes, I have. Pings stop after pulling out the cable.
I have grabbed one of my sensor nodes (temp/humidity) and put it on the mySensors sketch from the example. Question on that though, how does it know what radio to use? No where is it defined in those sample sketches.

I will post my sketch and the changes I've made to other files so you guys can get a complete picture.

Ok that web address for the wiring certainly helped (pin 10 was what I needed there). I'm getting output now saying gateway started but it doesn't seem to be listening on port 5003. I can ping the IP but not telnet to port 5003.
