ESP8266 WiFi gateway port for MySensors

[Yveaux]

@Daniel-Oliveira by downloading from the Arduino ide you will overwrite any firmware already in the flash. No manual steps are required. Just connect and download from Arduino ide.

Thank you for the quick response @Yveaux & @hek

I started working on the gateway today but I seem to be having a problem. I already had IDE version 1.6.5 installed with the board manager enabled. I've been creating some sensors on some ESP-01 for a few weeks without a problem. I replaced the MySensors folder I had in my library folder with the most recent one. My old sketches still compile but when I try to compile the ESP8266Gateway sketch I get the following error.

Esp8266Gateway.cpp.o: In function `incomingMessage(MyMessage const&)':

collect2: error: ld returned 1 exit status
Error compiling.

All I changed in the ESP8266Gateway example sketch was the SSID and Password.

Can you check the boardmanager which version of ESP Arduino you have installed?
Mine's like this:

I use the 'stable' version, located at http://arduino.esp8266.com/stable/package_esp8266com_index.json

Maybe your installation is inclomplete; you could try removing & reinstalling Arduino for ESP.

That was the problem, I was running an older version, I upgraded it and now it show's the same as your version.

Thanks again,

Mike

Just wanted to say thank you! It works great after hooking it up on my breadboard, now I can finally include MySensors in my sensor network 8-)

[Yveaux]

@jvandenbroek Great to hear it's working fine! Have fun!

[gmccarthy]

Great work. Just starting out with mysensors and looking forward to implementing this. Waiting for my hardware to arrive :)

Great work.

Your icon suggests differently :laughing:

I'm having problems compiling this - I must be missing something but can't figured out what.

Error:

Esp8266Gateway.ino:77:25: fatal error: ESP8266WiFi.h: No such file or directory

I've downloaded the mysensor library and unzipped it.

My sketchbook location is: C:\Users\xxxxx\Documents\Arduino

Under C:\Users\xxxxx\Documents\Arduino\libraries\MySensors\examples\Esp8266Gateway
Ads

The esp8266gateway.ino file is present.

Update: Pffft....try selecting the generic ESP8266 module :)

Built Mine :smiley: works great the only problem I had was uploading the code from a Mac OSX Mavericks so I opened a Win7 VM I keep for these type of problems and all is good. Thanks! @Yveaux :clap:

My Gateway has shrunk...

Great to hear you got things running!
@hek is also on Mac and he managed to download directly. Maybe you can discuss your issues with him so we can update the install instructions if something special is required for Mac.

My Gateway has shrunk...!

Sure did, and it's wireless now :laughing:

@DrJeff

I managed to upload on mac, but had to fiddle around before I got it working.

Added this text after my experience.
"This NodeMCU board normally can be flashed automatically and shouldn't need bootload/reset buttons to be pressed. If you see error, try changing baudrate from from 9600 to 57600. Still problems? Hold flash and press reset. Start upload in IDE while keeping flash-button pressed until upload starts."

[DrJeff]

@hek Yes I tried those but it's probably the driver install it was acting a little finicky so it was quicker to flip over to the VM. :)

@DrJeff
I remember that there was an error in the boardmanager-package for MacOS. You need to change the file-permissions to executable:

sudo chmod +x ~/Library/Arduino15/packages/esp8266/tools/esptool/0.4.4/esptool 

[rvendrame]

I followed the steps above, and I'm even able to upload sketches, however I only get this in serial monitor:

load 0x4010f000, len 1264, room 16 

Bad module maybe?

EDIT: After choosing the right board (v.1.0) and applying the fix above from @fleinze, it seems it is working now...

Hi,

I'm having problems running ESP8266 gateway. When I reset my nodes or trying send command from controller to node (dimmer, realy etc.) my gateway reset itself. I try using different ESP-s (I'm using ESP-12), power supplys and radio modules.

On serial monitor I get this error:

[Yveaux]

@krajcl What catches my eye is the client command echoed by the gateway: "Client 0: 44;255;3;0;6;"
The 0 at the end seems to be missing -- This could be a gateway issue (are you using the standard ESP gateway sketch, or did you make any modifications?) which causes e.g. the command parser to crash.

Could you give a more detailed description of your setup? Which controller are you using, what does the network look like (nr. of sensors, repeaters etc.).

[krajcl]

@Yveaux I'm using standard ESP gateway sketch (I reinstalled Arduino IDE, download latest mysensors library). At the moment I'm using MYSController as controler (for testing), I only have one node active (standard humidity sketch - only changed node id).

[Yveaux]

@krajcl The last command from the controller seems to be a response to the sensor to indicate metric or imperial units are used (internal command 6). The payload should be either 'M' or 'I'.
I'm not familiar with MYSController, but is there some setting influencing the unit system? Can you check if it has a valid value?
I can't replay the situation right now, so anything you can do yourself to track the problem would really help.

[krajcl]

@Yveaux This is result with Domoticz as controller and new node (relay), same result:
