ESP8266 WiFi gateway port for MySensors

How do you plan to connect the wired ethernet to the NodeMCU board?
You could probably connect a W5100 module through SPI, but why bother?

[A R]

@Yveaux I am using W5100. Its a system requirement. I want wifi connectivity with sensors through ESPs but the final data is to be routed through ethernet for security.

[Yveaux]

@A-R But do you use any MySensors parts then?

[A R]

@Yveaux No. I asked a simple question: can the GatewayESP8266.ino be used to send data from NodeMCU to Ethernet? If you have an answer then do reply.

[Yveaux]

@A-R No need to get all grumpy! I'm just trying to understand what you want to achieve, and help you out.
You are posting to a MySensors forum, so I assumed you are using MySensors software in your project.
Answer to your question: No.

[scalz]

@A-R : it depends of what you are connecting to esp8266, you didn't give details. esp8266 lacks of io, so it depends...I think you have not googled?? esp8266 w5100 for instance, you will find things...then if it is to use radio+w5100 with esp8266, sure it's possible but depends of available io...software spi you would have to double io, hardware spi, need manage your cs lines...some work. If it's just esp8266+w5100 there are already things on google...

Hi,

I have added som support, where the gateway can upload data to emoncms, transparant to other functions (not fully testet):

in gatewayutil add this in top of file, after the ARDUINO check:

#define EMONCMS

#ifdef EMONCMS
static WiFiClient emon_client;
const char* emon_host = "emoncms.org";  
const int emon_httpPort = 80; 
const int emon_addr_offset = 10;
#endif

---

Change this function to:

void incomingMessage(const MyMessage &message) {
//  if (mGetCommand(message) == C_PRESENTATION && inclusionMode) {
//	gw.rxBlink(3);
//   } else {
//	gw.rxBlink(1);
//   }
   // Pass along the message from sensors to serial line
   serial(PSTR("%d;%d;%d;%d;%d;%s\n"),message.sender, message.sensor, mGetCommand(message), mGetAck(message), message.type, message.getString(convBuf));
#ifdef EMONCMS
     if (!emon_client.connect(emon_host, emon_httpPort)) {
      Serial.println("emoncms connection failed");
      }

      emon_client.print(String("GET /emoncms/input/post.json?&node="+ String(message.sender+emon_addr_offset)+"&json={"+String(message.sensor)+":"+message.getString(convBuf)+"}&apikey=XXXXXXXXXXXXXXXXXXXXXXXXXXXX\r\n"));
      Serial.println(String("GET /emoncms/input/post.json?&node="+ String(message.sender+emon_addr_offset)+"&json={"+String(message.sensor)+":"+message.getString(convBuf)+"}&apikey=XXXXXXXXXXXXXXXXXXXXXXXXXXXX\r\n"));
#endif
} 

It will upload data with NODE ID and Sensor ID from the network, with an offset of emon_addr_offset...

Are there any one that can help me implement this in the dev version? Have a nodemcu 1-0 and got errors uploading the 1.5 version so i cant use that. Tried to fix it but ended up with the dev version.

Can anyone provide the correct wiring for NodeMCU (ESP-12E) to RFM69HW? I have seen several different guides that show connections for RFM69, but there are several different patterns and none have worked so far. Perhaps I didn't get it right, but this is what I've seen and tried:

someburner/esp-rfm69

RFM69->	ESP-12E
MISO	GPIO12
MOSI	GPIO13
SCK		GPIO14
CS/SS	GPIO15
DIO0	GPIO5
VCC		3V3
GND		GND
ANA		<antenna>

halburd/NodeMCU-Gateway

RFM69->	NodeMCU
NSS		GPIO2 (J2P5)
SCK		SCK (J1P9)
MISO	MISO (J1P8)
MOSI	MOSI (J1P6)
DIO0	SS (J1P7)
VCC		3V3
GND		GND
ANA		<antenna>

I've also determined that the following should also be correct, though again, they all don't match.

RFM69	ESP-12E	WEMOS D1	NodeMCUv3
MISO	GPIO12	D6/D12		D6
MOSI	GPIO13	D7/D11		D7
SCK		GPIO14	D5/D13		D5
CS/SS	GPIO15	D10			D8
DIO0	GPIO5	D3/D15		D1

I've also tried to figure out how to use the nRF24L0+ wiring, but that doesn't quite match either. If someone could simply post a working config, I could get some traction on my project.

[bkenobi]

Looking at the different charts, I've located some errors (I think).

Looking at someburner's setup, it looks like he is opting to use software SPI rather than hardware as the ESP pins for SPI are not on GPIO12-15.

Looking at halburd's code, it appears that he's opted to use GPIO2 for slave select and connect the actual SS to DIO0. I'm not clear why this is done, but it seems odd.

I lost the reference to the last chart. It also uses GPIO's for SPI rather than the built-in hardware SPI. The guide in this sketch is only documented for nRF24L01+, so it doesn't match exactly. But, it also uses GPIO 4, 12, 13, 14, 15. It seems odd to use those rather than the SPI pins.

I tried to get the ESP8266 gateway working for 2 weeks but kept getting st=fail at various times. Switching to a serial gateway fixed it straight away? Is this a known issue? Is it perhaps related to having the ESP8266 and the nRF24L01's so close together? BTW, I tied both the normal gateway and the MQTT gateway without much success. The who time I thought it was a radio issue :-/

This was all running on a NodeMCU v1.0.

@Mark-Swift Did you follow the connection in the ESP build guide?
Did you make any changes to the sketch? Which MySensors version did you use and which ESP Arduino version?
Just asking all these questions so we can be of better help.

[Mark Swift]

@Yveaux I believe so, the nNF24L01 is connected to a NodeMCU (I've tried feeding the radio off both the onboard 3.3v and via VIN and a 1117 3.3v regulator (I have caps across the radio GND / VCC).

No changes were made to the sketch - I'm using the latest development build (also on the nodes). I've tried with all of the ESP Arduino board versions, doesn't seem to change anything?

@Mark-Swift said:

Now I read over your post again I get the impression that it sometimes works, and sometimes you get st=fail. Is this correct?

[Mark Swift]

Example - I'm sat here right now with one of my nodes and the gateway connected to my Macbook via USB.

When using the serial gateway I get =ok after each item no problem; in fact I can't make it fail.

When using the ESP8266 MQTT gateway I get:

@Mark-Swift It does work sometimes, so that rules out a lot of possible problems!
How do you power the NodeMCU & rest of the hardware?
Both NodeMCU & nRF are very sensitive to low/noisy supplies.

[Mark Swift]

@Yveaux I power the NodeMCU from either my Macbook Retina, or from a decent USB wall plug, tbh, it seems to make little difference which I use. I presume everyone else is powering them via the USB also?

I've also tried a spare NodeMCU and a bunch of radios. In fact, I've been trying to get this working for 3 weeks, it's literally going to cause a divorce soon :-/

[Yveaux]

@Mark-Swift The log mentions Moisture Sensor, Rain Sensor, LUX, Distance.
Are these real sensor connected (and yes, how) or virtual?

[Mark Swift]

@Yveaux real sensors connected to my robot mower garage node...

[Mark Swift]

@Yveaux Node code is here for reference:

[Yveaux]

@Mark-Swift To be frank: I don't know.
I'm quite sure it has nothing to do with the ESP port, or software in general.
You could try different orientation of the nRF, or move it closer to the sensor(s).

Are you using an amplified nRF24 btw?
