ESP8266 WiFi gateway port for MySensors

[Yveaux]

@vickey could the nrf24 be defective?
Did you obtain the gateway & MySensors code from my github repository or from MySensors repository?

[vickey]

Sorry When I investigate the wiring throughly, MOSI and MISO was interchanged. Now it has started working but error has changed

I obtained the code for gateway & MySensors from MySensors repository on github.
what would be the problem now?

I would like to use this tutorial for MySensors in the openHAB program:
http://forum.mysensors.org/topic/1194/tutorial-openhab-with-serial-gateway

I have the ESP8266 WiFi gateway working over a telnet session in Putty.

Is there a way to have openHAB communicate over telnet like a hardwired serial interface?

Has anyone used this yet?

@ridge sorry, can't help with that. Everything's MQTT over here :-)

[ridge]

Thanks! Are you using this gateway with a controller or is it a proof of concept?

It is fun to watch the states respond in a telnet session. I am having trouble finding any mention on how to use this with a controller.

[Yveaux]

@ridge its use should be no different then when using the Ethernet gateway (because it is an Ethernet gateway :-) )
I'm using it with OpenHab through MQTT and NodeRed through MQTT.

[ridge]

Is your setup using this gateway like:

MySensors network <=>Gateway <=> Format conversion program <=> MQTT broker <=> openHAB

For some reason, I had assumed that the results of the gateway could be used directly in openHAB.

@ridge

Tried this?

[ridge]

Thanks hek, OpenHAB 1.7.1 is stable for me. I will probably wait for openHAB 2.0 to get closer to production status before wading in.

I understand serial binding.
I understand MQTT binding.

I am missing something stupid easy in understanding ethernet binding.
Do I include the http binding in the addons folder?

A serial connected device is defined in an openHAB items file like:
Switch HardwareButton "Bell" (Entrance) { serial="/dev/ttyS0" }

I just cannot find an example of what an ethernet connected device would use in place of the "serial" definition.

Yes. Production gateway is currently (cabled) ethernet gateway, "Format conversion program" is this perl script and MQTT broker is Mosquitto.
Perl script, Mosquitto and OpenHab run on Ubuntu 12.04LTS server PC.

@ridge

You could always use ser2net to emulate a serial port connected to the ethernet gateway from you openhab box.

[ridge]

Thank you hek and Yveaux. I thought I had missed something obvious. For the present with openHAB 1.7.1, a small piece of the wireless sensor data super highway of the future is still under construction! In that case I will certainly study the MySensors gateway to MQTT broker examples closely.

Hello guys,

I am having issues with this installation. I got everything up and running but it simply doesn't connect to my WiFi Netgear router at home.

I just enabled my hotspot on my cell phone and the gateway did connect successfully and started the gateway master with IP, etc assigned.

When I try to connect to my home WiFi it just keeps on printing dot dot dot in the serial console.

My Netgear has two networks with 2.4Ghz and 5Ghz. I tried both and none of them worked. They are configured with WPA2-PSK [AES] encryption for the passphrase and the passphrase has one special character included. The SSID is 5 characters long and the passphrase is 22 characters long which shouldn't be an issue.

I don't get any error messages in the serial console and my router doesn't show anything in the logs either like the ESP gateway doesn't even try to connect. I don't know how to troubleshoot this from here.

Any help would be appreciated.

[hek]

I also have both 5/2.4Ghz on my router.

When ESP connects is seems to prefer 2,4 GHz / n / WPA2 if that helps.

[Pseudomizer]

This is what I have. 2,4 GHz / n / WPA2 (no TKIP but AES instead so I can go beyond 54Mbit) and it doesn't connect. Just dots coming up.

[Yveaux]

@Pseudomizer Esp8266 is 2.4ghz only.
You could try adding the following line just after hw_init() in the sketch:

Serial.setDebugOutput(true);

It will dump a lot of ESP WiFi related data, please post the output here. Maybe some will give a hint of what goes wrong.

[Pseudomizer]

Thanks a lot for this. This helped me troubleshoot the problem and I am surprised why it didn't connect. It couldn't find my SSID name because in the router it is all UPPER case but when I write it on any other machine Windows, Linux, etc to connect to, I always write it lower case with the exception of the first character.

In this case I modified the sketch to have the SSID name all in UPPER case and voila it connected.

Thanks again for the help here. Much appreciated.

[Pseudomizer]

I was very happy when it connected but now it is resetting itself constantly with this error message:

wdt reset
load 0x4010f000, len 1264, room 16
tail 0
chksum 0x42
csum 0x42
~ld

Any ideas why?

I missed one line of error code above:

ets Jan 8 2013,rst cause:4, boot mode:(3,6)

[Pseudomizer]

I tried my Home Wifi and my Cell Hotspot. The crashes occur on both wifi networks. :-(
