ESP8266 WiFi gateway port for MySensors

[Yveaux]

@D_dude I searched the net for a description of reset causes and boot modes but failed to find one.
I have no clue of what they mean.

[D_dude]

@Yveaux
thank you for your assistance. I will try adding some debug in the code on the weekend to see what exactly is not running and possibly causing crash.

[mfalkvidd]

I got a suggestion here to erase the flash before flashing. Haven't tried it yet, but it might help you @D_dude

[D_dude]

@mfalkvidd
Thank you, i will try this and post results.

[D_dude]

@mfalkvidd
tried erasing the flash using the method suggested but doesn't seem to be working for me. same result.
Thanks for the tip though.

[mfalkvidd]

Too bad. Thanks for posting your results.

[luisgcu]

here is my ESP8266 wifi gateway installed in wifi repeater box, taking the advantage that its has a 5 volts power supply.

[Yveaux]

@luisgcu Nice housing!
Thanks for the pics!

I'd been using the ESP gateway for several weeks, but recently was having trouble adding a new sensor I am developing.

Since the copy of dev I built it with was now out of date, I went ahead and updated... still wasn't working right so while I had the serial link to it I checked and noticed it was crashing and cycling. It would work for hours, until I fired up my new node, then crash about immediately. A few dozen debug(PSTR())'s later, I found a cause.

In core/MySensorsCore.cpp the result of _msg.getConfig() is dereferenced in a comparison, and it's possible it could return NULL ( like when it's a new node ). I put a check around that and it's not crashing anymore. Which is more than what I can say for my new sensor node....

I have not tested this change with an AVR.

I submitted PR 264.

[mfalkvidd]

Great work @soward !

[D_dude]

on some basic debugging, seems like my sketch is crashing in setupGateway.

infact even adding a print statement, it only prints first 3 chars.

My question is setupGateway takes output as an arg, which in turn is a function, should there be some parameters for this function?
also "Serial.print(serialBuffer);" does not print anything i added prints above and before and they don't show up either.

  va_end (args);
  Serial.print("A1");
  Serial.print(serialBuffer);
  Serial.print("A2");

any suggestions?

[Yveaux]

@D_dude flush the serial output after each print.
The ESP will output the serial data in the background while your programm continues and then it crashes.

Hi,
I'm getting all the time this:

Then it got stuck so I do reset and getting this in loop:

Means there's something wrong with your nRF communication. The WDT reset following this is normal.

i have been using wifi gateway with Domoticz controller without any problems until recentely. After the last update to beta version of the controller, the gateway crashes when the controller request gateway version:
Gateway startup complete.
Client 0: 0;0;3;0;2;

Exception (28):
epc1=0x4000bf80 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

ctx: cont
sp: 3ffebf60 end: 3ffec1f0 offset: 01a0

I have tested with telnet client with the same request and it was ok. Then I saw that the request from controller was terminated with only <LF> and not with <CR><LF> and this is why it crashed. I have added the following to the sketch:

•    if (inChar == '\n')
    {  
      if (inputString[i].string[inputString[i].idx-1] != '\r') { // if the last char is not CR then add it
      inputString[i].string[inputString[i].idx++]='\r';
     }
      // a command was issued by the client
      // we will now try to send it to the actuator
  

and now it seems to work.
Is this the right way to go?
Thanks

@ciprian

Are you talking abut this line of code?
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/core/MyGatewayTransportEthernet.cpp#L194

[ciprian]

@hek My code is from GatewayESP8266.ino example in Mysensors 1.5, line 234.

[hek]

Ok! Mis-read this line---

After the last update to beta version....

Thought you were talking about the development branch. Sorry.

[Yht]

Hi all,
First, I have to say this is awsome what @Yveaux did, thank you!

Sorry if this question takes you back in time. I don't know what channel and id to use for the nodes,I tried channel 97 and id from 1-5 but it is not working..
are you using mesh lib?

[Yveaux]

@Yht said:

I don't know what channel and id to use for the nodes

Just leave the default channel untouched for both sensors and gateway. It should be fine.
The gateway will automatically be assigned ID 0, the nodes can have any fixed ID.
Dynamic ID assignment requires some extra software, as the gateway does not support it.

I'm also seeing my ESP8266 gateway crash when the controller requests its version.

I had not seen this thread so I started a new topic here: http://forum.mysensors.org/topic/2493/esp8266-wifi-gateway-crashes-and-reboots-when-controller-connects

[scalz]

hi,

maybe you have already seen it...but you can get cheap and smaller nodemcu. crazy price! I have ordered some, and waiting for them...

[Yveaux]

@scalz Nice! Thanks for the link!

[drock1985]

Just wanted to chime in and say thank you for this gateway script @Yveaux

I originally had an ethernet gateway for the longest time. But when I changed over to an OnHub router, it stopped working because it doesn't like to handle static IP, and the current branch sketch is too large to enable DHCP. This worked wonderfully with the OnHub out of the box (ver 7390.62.2) and shows up with a hostname of ESP_DA7D8B.

Thanks again!

Hi,
When testing the ESP8266MQTTClient (downloaded latest version of the library today) and compiled with the NodeMCU 1.0 ...... option I get an odd result. The message at startup is (please disregard the "Radio init fail" - the radio was not yet connected. I just wanted to check the WiFi

2dO,4`lLMØl 8ðÿ0;0;3;0;9;Starting gateway (RNNGE-, 1.6.0-beta)

dhcp client start...
ip:192.168.1.167,mask:255.255.255.0,gw:192.168.1.1

I can see from the router that the connection to 192.168.1.167 is successful but the oddity is that I have set the gateway to use a static address and also connect to a SSID which is not XXXyyy. The defines are:

// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
#define MY_IP_ADDRESS 192,168,1,22
// If using static ip you need to define Gateway and Subnet address as well
#define MY_IP_GATEWAY_ADDRESS 192,168,1,1
#define MY_IP_SUBNET_ADDRESS 255,255,255,0

So the ESP8266 uses dhcp when it should have a static address and connects to a SSID which is not given but may have been previously used at earlier tests.

I have looked at the code and tried a few changes to defines but none resulted in the override of dhcp.
Anyone have a clue?

I have the exact hardware in this setup but can't even get to the point where the hardware is a problem! I'm having compile errors during verify that make no sense and that I can't seem to find in the forums using search:

In file included from Esp8266Gateway.ino:69:0:
C:\Users\xxxxx\Documents\Arduino\libraries\SPI/SPI.h:982:8: error: 'SPIClass' does not name a type
extern SPIClass SPI;

Any suggestions? I'm running windows 10 and Arduino 1.6.5 with the most current esp8266 board files through board manager.

Apparently me and anything arduino related are like oil and water, yet I keep buying the stuff.

I tried this on my laptop and it worked fine (the compile verify did anyway) so I'll be reinstalling the IDE and trying again and hopefully that resolves my issues!

[tjay4x4]

Yesterday I have successfully installed the ESP8266 module and it works fine, but the Vera3 show something strange now.

Has anyone experienced this?

[Yveaux]

@tjay4x4 Seems like to be an issue again when going from 8-bit to 32-bit architecture.
Can you connect the ESP to your PC and capture the serial output when connecting to your lights and controlling them?

[tjay4x4]

@Yveaux Thank you for reply. Here is the serial monitor.When I put 100% light it shows Ok. But 70% and others, shows some digitals. But all working fine!

[tjay4x4]

@Yveaux Now everything working! I reinstall all "Arduino-master" to Arduino 1.6 folder and now ALL Ok. Sorry for disturb. Thank you!!!

[Yveaux]

@tjay4x4 try development version of MySensors. This thread discussions a similar issue:
http://forum.mysensors.org/topic/2118/esp8266-wifi-gateway-issue/2

[Yveaux]

@tjay4x4 Just crossed my reply! Great it's working now!

[robosensor]

Yesterday I switched gateway hardware from serial gateway based on arduino pro mini 3.3V and nrf24l01+ (connected directly to uart port of my mikrotik router) to esp8266 nodemcu and nrf24l01+ (exactly as at this page: http://www.mysensors.org/build/esp8266_gateway, using GatewayESP8266 sketch from 1.6 branch, revision https://github.com/mysensors/Arduino/tree/1035f84a431a8f591d31100c3e73e99a8245e345).

I have 4 nodes with ~27 sensors total, half of sensors sending data every 10 seconds, another sensors send data only if environment changed.

After switching to esp8266 my gateway started loosing packets (messages) from my sensor nodes:

Left side of graphs is esp8266, right side is old pro mini serial gateway, sensors sending data every 10 seconds. Distance between gateways is about 5-10 centimeters. Both nrf24l01+ boards oriented in the same direction.

nrf24l01+ board isn't changed at all (I'm using old board from pro mini serial gateway).

Also, I have tried different nrf24l01+ boards (different PCBs and different chip revisions, but seems like all of them are fake china chips). I have tried soldering 220 uF electrolytic and 0.1 uF ceramic capacitors directly to nrf24l01+ power pins. But nothing changed. Esp8266 gateway is losing messages.

Switching back to pro mini serial gateway is completely solves issue (as shown in graph above).

What else can I try to fix this? Could it be interference between wifi chip and nrf24? Or, maybe, this is software problem? Maybe non-interrupt driven polling of nrf24l01 causes loosing messages coming too often?

[hek]

@robosensor

Interesting graph... But I have no immediate answer to you.

[robosensor]

@hek graphs are drawn by Zabbix. My own Perl script connects directly to gateway, reads sensor data and sends this data directly to Zabbix.

Also, I have tried to write raw data from gateway directly to file and execute "tail -f logfile.txt | grep sensor-specific-id". With old pro mini gateway data from sensor comes every 10 seconds. From esp8266 gateway sensor data comes very irregular.

Also, every send() call in all my nodes followed by wait(25) call to reduce possible power issues and interference issues.

UPDATE: I have recompiled esp8266-gateway sketch with debugging enabled, but I get the same results with loosing messages then I connecting directly to uart port of esp8266 uart-usb converter.

[Yveaux]

@robosensor What strikes me is the fact that most of the time not all sensor values seem to disappear at the same time. A failing WiFi connection would be the most likely cause when all dis/reappear at the same time (like at 13:44 and 13:22).
However, most of the time at least one sensor seems to report its values correctly. IMO This rules out the radio.
Is there anything interesting in the serial logs?

[robosensor]

@Yveaux thank you for your reply. It is not failing wifi connection, as the same problem exists then I using serial connection to esp8266 (via on-board usb-uart converter on nodemcu board).

Nothing interesting in the serial logs (with debug mode enabled), just random absence of sensor data. Seems like I should connect sensor node to collect debug logs from node side.

Also speed is changed - much faster CPU (80 MHz vs 8 MHz) and much faster connection (wifi vs uart 9600 bps). Maybe this affects.

[robosensor]

Seems like problem with loosing messages is gateway firmware related.

Then I connect two controllers (my own perl script and MYSController 0.1.2.282) to esp8266 gateway (#define MY_GATEWAY_MAX_CLIENTS 2), both controllers receiving exactly the same data from gateway, but messages lost even more.

1 on graphs = one controller connected
2 on graphs = two controllers connected.

I'm not familiar with esp8266 network programming, but could it be that firmware looses incoming packets from nrf24l01+ due to blocking call to wifi-related network functions? Seems like during sending data to wifi network firmware does not have time to pick up all incoming packets from nrf24l01+ chip.

[robosensor]

I think I found problem. As I said before, seems like WiFi's clients[i].write() call blocks thread for a very long time.

I added logging of write() time:

		// Send message to connected clients
		#if defined(MY_GATEWAY_ESP8266)
			unsigned long start_time = hwMillis();
			for (uint8_t i = 0; i < ARRAY_SIZE(clients); i++)
			{
				if (clients[i] && clients[i].connected())
				{
					clients[i].write((uint8_t*)_ethernetMsg, strlen(_ethernetMsg));
				}
			}
			debug(PSTR("WiFi transaction time: %u ms\n"), hwMillis() - start_time);
		#else
			_ethernetServer.write(_ethernetMsg);
		#endif

And got following results:

Seems like many packets coming to NRF24L01+ in this time interval (140-200 milliseconds) and this causes NRF buffer overflow and packet loss.

[hek]

Damn, 200 msec is a pretty long time.

[Yveaux]

@hek Yeah, but is this significantly longer than for a wired connection?
Only real solution would be to switch to interrupt based message handling for the MySensors network (hopefully the ESP stack can handle this...)
@robosensor Are these long delays (only) caused by the fact that this is a long distance connection?
How is your mileage for a server on e.g. the same lan?

[Fabien]

Exactly same problem here with RFM69W Radio. With 2 clients, i loose more packets. Both controller and ESP are on the same LAN. No probelm with Serial Gateway on Jeelink v3.

[robosensor]

@Yveaux seems like delays caused by low-level network/tcp code or settings of receiving side (maybe something as TCP ACK packet delays or Nagle algorithm or something like this).

ESP8266 connected directly to Mikrotik RB2011 router.

Then I connect from external server (ping to server is about 55 milliseconds, FreeBSD 9.3, Perl), delays about 140 milliseconds.
Then I connect from windows-based computer, connected directly to router, delays about 200 milliseconds (both windows telnet and PuTTy).
For 2 parallel above connections delays about 350 milliseconds.

Then I connect from router's internal telnet client, delays about 1-2 milliseconds
Then I connect from android-based phone (phone connected to router via wifi, using ConnectBot software), delays vary from 3-5 milliseconds (mostly) to 100-150 milliseconds (less frequently).

Seems like interrupts for nrf24 is the only solution. Seems like esp8266 gateway with such delays is completely unusable with high packet rates. With ~150 milliseconds delays no more than 6 messages/second packet rate allowed.

Just to reference: I'm using Arduino 1.6.5 with esp8266 libraries version 2.0.0 installed.

[Yveaux]

@robosensor @Fabien Please understand that this issue is not related to ESP8266. I expect delays to be nearly identical when using the Ethernet gateway (wired ethernet) and ATMega microcontroller. Of course the serial gateway will not suffer from these delays as it doesn't use ethernet as transport medium -- it is a direct connection.
Switching to interrupt-based message handling for the MySensorts stack is not a simple task. It will require locking and buffering, and footprint of the library (especially RAM) will increase.
Furthermore I don't know how the ESP's network stack handles interrupts during ethernet processing. Worst case it will just block interrupts or run from a higher-priority interrupt than the nRF and all efforts of making the MySensors library interrupt based will be in vain.
I personally would try to reduce the latency in your server connection by choosing a server nearby or by buffering your traffic by a server in your LAN. MQTT for example can easily be buffered by a local broker which then uses the slow connection to sync with another server.
Another option is switching to a serial gateway, but again you need a local server inbetween.
A simple Raspberry Pi or so could act as a server for these scenarios.

Another option would be to implement a retry mechanism on your sensors. If the gateway does not confirm reception of your message, then resend it.

[robosensor]

@Yveaux I completely agree with you. Rewriting gateway code to support interrupts is not very easy task and it is not clear what problems you will encounter. Furthermore, rewriting will not solve the problem of delays, this only can solve packet loss problem.

Just tried to connect from RPi 2 (connected using WiFi directly to router), average delay is 2-5 milliseconds, sometimes 5-10 ms. Seems like this is good temporary solution.

[D_dude]

@Yveaux said:

@D_dude flush the serial output after each print.
The ESP will output the serial data in the background while your programm continues and then it crashes.

Finally was able to get everything working.
Ordered a fresh nRF from Itead and started from scratch. everything worked fine first time. seems like the nRF from ebay was causing issues.

[robosensor]

Just tried old version of esp8266 libraries (1.6.5-947-g39819f0 instead of 2.0.0) with old version of esp8266 gateway (master branch, commit 9ef2604c81d2fea5d646a9a194f312192833a79b) and got exactly the same results.

WiFi write() time is about 150-200 milliseconds for remote server in another country, 200-210 milliseconds for windows7-based computer in local area network and 0-4 milliseconds for Raspberry Pi 2 in local area network.

To show transaction times just replace original output function in Esp8266Gateway.ino with following code:

Also disconnection of client during clients[i].write() call causes reboot by watchdog:

WiFi write() time is about 150-200 milliseconds for remote server in another country, 200-210 milliseconds for windows7-based computer in local area network and 0-4 milliseconds for Raspberry Pi 2 in local area network.

So another confirmation of what we knew already.

Do you know how many nRF messages are actually sent during this wifi write call?
The nRF has a rx buffer for 3 messages -- not sure if MySensors uses all 3 of them.

Also disconnection of client during clients[i].write() call causes reboot by watchdog

I guess this is ESP core related. Is this fixed in code 2.0.0?

@Yveaux said:

Yes. It seems that I now understand what is happening. WiFiClient::write() blocks thread until TCP ACK packet received or until timeout (5 seconds). Windows sending TCP ACKs after 200ms timeout. That's why write() delayed for ~200 milliseconds for windows-based controller. More information (and link to non-blocking library) is available here: https://github.com/esp8266/Arduino/issues/922

Do you know how many nRF messages are actually sent during this wifi write call?
The nRF has a rx buffer for 3 messages -- not sure if MySensors uses all 3 of them.

Nodes sending 3-7 (sometimes more) messages with 35 ms delay between messages, so in my case 3-packet hardware buffer in nrf24 is overflowed after 105-140 milliseconds of write() call.

I did not tried to check this reboots in 2.0.0, but 2.0.0 is much more stable and I never seen any reboots/resets.

That sounds promising! I'll have to give the 2.0.0 core a try myself then.

[patrick schaerer]

Thanks for your work!
I made my wifigateway today and added variables for a static IP Adress.
I also tried to add an DHT11 to the wifi gateway, but it didn't work. I cannot include those sensors because I need to startup while inclusion and this would restart the gateway.
Mabe someone has an Idea how to add a sensor to the wifi gateway. edit: I found this thread on the forum ... http://forum.mysensors.org/topic/1387/sensors-on-gateway

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Henrik EKblad
 * Contribution by a-lurker and Anticimex, 
 * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
 * Contribution by Ivo Pullens (ESP8266 support)
 * 
 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the WiFi link. 
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * VERA CONFIGURATION:
 * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin. 
 * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
 *
 * LED purposes:
 * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error  
 * 
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.
 * The ESP8266 however requires different wiring:
 * nRF24L01+  ESP8266
 * VCC        VCC
 * CE         GPIO4          
 * CSN/CS     GPIO15
 * SCK        GPIO14
 * MISO       GPIO12
 * MOSI       GPIO13
 *            
 * Not all ESP8266 modules have all pins available on their external interface.
 * This code has been tested on an ESP-12 module.
 * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
 * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
 * - Connect GPIO15 via 10K pulldown resistor to GND
 * - Connect CH_PD via 10K resistor to VCC
 * - Connect GPIO2 via 10K resistor to VCC
 * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
 * 
  * Inclusion mode button:
 * - Connect GPIO5 via switch to GND ('inclusion switch')
 * 
 * Hardware SHA204 signing is currently not supported!
 *
 * Make sure to fill in your ssid and WiFi password below for ssid & pass.

[Alex B Goode]

Any chance to achieve some success using ESP-01 or I really have to buy ESP-07/12?

I just have some ESP-01 modules already and I wonder if I can use them

[Yveaux]

@Alex-B-Goode the Spi bus is not available on the esp01 header, so you won't be able to connect the radio then...

[hek]

But I guess you could use it as a sensor node (mqtt/ethernet).

[sdndba]

@Yveaux said:

@krajcl Does it only crash when sending this particular message?

It's late (early morning) I did not want to read over all the last three months posts so my question... is there a solution for this problem? I just downloaded the latest library and found the NodeMCU will reboot when a node initializes. Data below. Just point me to the solution if you would please. Thanks very much.

@Yveaux
Is there any specific reason on why CE is plugged on D2?
I'm asking as I want to add a BME280 sensor directly on my gateway and by default the I2C bus is on D2/D1. It can be changed to any pin with Wire.begin(SDA,SCL) so it is not a major problem, but for user friendliness it would be nicer id CE was plugged on D9 or eventually D4 or D3.

If there is no specific reason can I change MyConfig.h line 329 to #define MY_RF24_CE_PIN 3 safely?

Thanks again for this gateway!

[Yveaux]

@emc2 said:

Not that I know of.

[emc2]

Switching it to D9 and adding #define MY_RF24_CE_PIN 3 directly to the program worked indeed.

Now everything seems to work either by moving the I2C bus or the CE. It may be nice to officially free up the I2C port on the next versions of the library by default? It could be easier than to modify each I2C sensor or even display libraries individually.

I will let it run a little while and if I don't see any major problem I will try to put the code in a new topic. Thanks for your fast answer @Yveaux !

[rapzak]

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"));

#endif
} 

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

hi.

Has someone already thought about using websockets with wifiGW ??? before I start to reinvent the wheel!
I have already made some tests with websockets but it was not with mysensors. it was not big tests too but I was able to have an html5 client with js. it was a simple test like blink led+serial monitor, receive/sending serial things. very simple!
I did this because I would like to have sort of display on my phone even if there are no controller. and I don't want to use spiffs and webserver. I prefer to have the stuff on client side and esp8266 acting as a simple websocket server. More lightweight I think, to handle something more complex if needed...For the client, then it could be html+boostrap or something more hybrid. I am not expert at this but I should be able to make some poc..but I don't want to waste my time if it already exists! I have lot of other projects so I don't know how long it could take, and maybe someone is faster on this, so it depends..but it's a feature I would like to have in future and I will make it when needed

So what do you think ??? dumb idea?

[hek]

Yeah, thought about it the other day and found this.

https://github.com/Links2004/arduinoWebSockets

Would have been fun to create something cloud.mysensors.org where people could share sensor data (and of course make it embeddable on the forum). Creating a websocket gateway-variant would probably be my first choice if I decide going down that path.

It also seems to support wss which is kind of nice.

[scalz]

@hek : cool so you think it could be useful too.
yes I use this lib, nice features and simple to use.
so, even if someone has already done something, maybe I will dig a little for fun, time to time...

[hek]

I haven't done anything yet. The old head is just constantly spinning ideas you know

So please go ahead and see if you can create a MyGatewayTransportWebsocket.cpp

[ErrK]

@scalz @hek you can look at socket.io if you are thinking of using websockets.

[hek]

@ErrK said:

socket.io

Yep, use it on my dayjob. Allows downgrade to polling which (I guess) the Arduino library doesn't support. Might be better to use raw websocket on the server side in this case.

[scalz]

@ErrK : yes I saw it too. but here a discussion about socket.io with esp websockets https://github.com/Links2004/arduinoWebSockets/issues/42
very interesting

[Yveaux]

@scalz @hek a local server on the ESP serving gateway status overview (connected clients, routing table, sensors presented by clients, data etc) would be a very nice addition to any gateway IMHO.
The ESP has enough power/flash to implement this.

[ErrK]

@hek: Yes, it has fallbacks to use other protocols. I think there is a setting if you don't want to use all the default protocols.
@scalz: interesting discussion. It looks like the best way shuld be to only use the websockets

[scalz]

@Yveaux: exactly what I was thinking for monitoring and it could be fun to be able to show something on the phone without a controller (for instance when I visit my not geek friends, it looks more simple if something on the phone instead of setting up a controller).
I started to look at dev branch last night but was too tired.... I visualize where are the changes to do, but maybe not all, I will ask you if I have some problems A cool thing in websocket lib is broadcasting client is already implemented in it.

Hi,
I am working on a sensor system. Sensors feed to ESP8266 which feed to NodeMCU ESP8266. I saw in the intro to GatewayESP8266.ino on GitHub your code which says:

• The EthernetGateway sends data received from sensors to the WiFi link.
• The gateway also accepts input on ethernet interface, which is then sent out to the radio network.

Does that mean Ethernet Gateway receiving data from WiFi?
Thanking you in anticipation.
Riaz Ahmed

[Yveaux]

@A-R said:

As the topic indicates this is a WiFi gateway for mysensors. That means that it converts sensor data from the MySensors network to WiFi and vice versa.
When sending data to a sensor, a controller will send data over WiFi to the gateway, which then sends the data on to a MySensors sensor (using nRF24L01+ or RFM69HW radio).
Seen from the controller, it will communicate to the WiFi gateway exactly the same way as it would when connecting to a wired ethernet gateway.

[A R]

@Yveaux Thanks for the reply. Let me elaborate please. My sensor sends data to ESP8266 which sends it to NodeMCU ESP8266. From there I want the NodeMCU ESP8266 to send data through a wired Ethernet. (from there i want it be sent to a router).

So my question is can the GatewayESP8266.ino be used to send data from NodeMCU to Ethernet?

[Yveaux]

@A-R said:

can the GatewayESP8266.ino be used to send data from NodeMCU to Ethernet?

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...

/Rapzak

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.

[bkenobi]

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.

[Mark Swift]

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

[Yveaux]

@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?

[Yveaux]

@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:

[Yveaux]

@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:

http://pastebin.com/mxkLq1Rp

[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?

[Mark Swift]

@Yveaux That's a shame, I'd really like to solve this. I've tried the radios orientated different ways but it makes little difference. Not using a PA+LNB, I was but gave up on it as I thought it was the issue (Now realise it wasn't).

Strange that I only see these issues with the ESP, and as soon as I switch to a Nano running the serial gateway they're gone.

[Yveaux]

@Mark-Swift I always use my sniffer in this case to see what's going on on air, but I don't know if your marriage will survive another sniffer build

[Mark Swift]

@Yveaux I doubt it will, seems I'm destined to build a serial gateway, crap, I've invested so much time in this and tried everything!

[Mark Swift]

@Yveaux How about this, for a laugh I just tried rolling the ESP8266 gateway back to v1.5 (master).

Guess what? It works every time with no fails (communicating with my 2.0.0 beta node). So the issue lies with the latest development version somewhere, any ideas?
~~
Insane, I just took the gateway down the other end of the house and not one fail, wow! So okay, what was changed in version 2.0.0?

UPDATE: After more investigation, the reason it was working is because v1.5 only has a straight forward gateway version, and until now I've been using the MQTT client. It seems the gateway versions work fine, but the MQTT client version create the fails!

UPDATE 2: Okay, I can reproduce the fails with the gateway too, let me try and explain. When the gateway is not connected to anything (for example Domoticz) I get OK all of the time, no fails whatsoever. If I connect to Domoticz, I start to get fails against certain child sensors (it's always the same!). I presume it's sketch related, or even the amount of node updates I'm sending? As I believe the fails are the same I'm seeing with the MQTT client.

UPDATE 3: Nearly 3 weeks in and I've just figured out what has been causing me all this pain. I've always commented out the default 9600 serial baud define on the ESP8266 sketches. It seems this combined with the 200ms TCP delay has been causing me my issues when connecting to my Windows 7 machine. S$%&*!

[Yveaux]

@Mark-Swift Well, look on it from the bright side: your marriage is saved now :bowtie:
There have been more reports from issues with connections to external servers (e.g. MQTT, Domotiocz) that take too long.
Maybe we should pull @hek in as he wrote the MQTT client for ESP.
