ESP8266 WiFi gateway port for MySensors

[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

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:

[rvendrame]

I'm definitely not a expert at all on the topic, but could it be that a ftdi-usb adapter doesn't provide enough power to ESP, and it eventually hangs when wi-fi transmissions drawn too much power? (according to the specs, ~150mA when transmitting) .

Just trying to help with some (probably dumb) brainstorming. ;-)

[gmccarthy]

Do you need to the NodeMCU to implement this?
I have an arduino uno and ESP-01. How do I wire these up?

After doing some more reading looks like the esp-01 does not have enough pins. Dont think I can use it :(

[Yveaux]

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

[krajcl]

@Yveaux I tried function (clear routing table) in MYSConroller. This is result:

Client 0: 0;0;3;0;10;C
Client 0: 6;0;3;0;10;C

ctx: cont
sp: 3ffeabe0 end: 3ffeaf20 offset: 01b0

When I try this function for gateway, evrything works fine, but for other nodes - gateway resets

[Yveaux]

@krajcl When this message is addressed to the gateway (0;0;3;0;10;C) it does not get sent over the air by the radio.
When you send it to node 6 (6;0;3;0;10;C), it will send the message to the node, using the radio.

Can you please answer this: Will it crash with just any message sent to the nodes using the radio, or only when sending internal messages to nodes (internal messages to nodes have the first value unequal to 0 and the third value set to 3, like 6;x;3;x;x;x) ?

[krajcl]

@Yveaux it doesn't matter, what I send, resets every time
