ESP8266 gateway - Connection refused

[Bram81]

Hi,

I'm trying to use a esp8266 gateway as a standalone node and let it connect to Domoticz. After some hick ups I managed to compile my sketch. The gateway boots, but I'm not sure if it gets connected the right way. Serial log shows:

0‚~?–$û!ƒ{ƒOAaû0;255;3;0;9;Starting gateway (R-NGE-, 2.0.0-beta)

In Domoticz I've added a Mysensors Lan Gateway in Hardware, with remote address 192.168.2.242 and port 5003. Which is opened in my router for 192.168.2.242. Domoticz log keeps showing:

2016-02-22 12:48:16.489 Error: MySensors: Error: Connection refused
2016-02-22 12:48:16.490 Error: TCP: Error: Connection refused

The inclusion button in the sketch is disabled, but inclusion time is set to 60 seconds. Could this be part of the problem?
Hope someone can help..

Is the gateway address really set correct? Looks a bit weird.

[Bram81]

gateway address must be my internet gateway right? In that case 192.168.2.254 is correct.
#define MY_CONTROLLER_IP_ADDRESS 192, 168, 2, 1 is my Domoticz server. Is that the way to go or am I doing something wrong?

I don't think Domoticz allows node to connect.

You should use it the other way around (let Domoticz connect to the gateway).

(and disable that define)

[Bram81]

I tried it the other way around, but still no improvement.

}

send( msg.set( sendValue ) ); 
sleep(9000);
}

Serial log of arduino shows:

the number 65535 keeps being printed like every second, which seems strange to me.

MY_USE_UDP

Why did you enable this?

[Bram81]

Because further down is stated:

// Controller ip address. Enables client mode (default is "server" mode).
// Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere.

My assumption was that I want it both to be a client and have it's data send to my domoticz controller, but obviously this isn't the way to go..?

[Bram81]

disabled MY_USE_UDP and it's connecting now... Thanks, feel pretty stupid.. Attaching the humidity sensor does cause de gateway to a reboot loop. Could that be a power issue since it's connected to my laptop's usb right now?

So.. I am VERY confused.. The 8266 wifi gateway doesn't have to have my zwave controller (vera UI7) ip address defined anywhere? I used to have this working, but just started over with the released version of the 2.x code, so I deleted EVERYTHING relating to arduino and MySensors, and started over.
With the generic GatewayESP8266 code, as soon as I enable the "#define MY_CONTROLLER_IP_ADDRESS 192, 168, 1, 185" which I thought was what was telling the code where to gind my Vera, it no longer compiles, but from what I think you're saying in this thread, I dont need to do that? Without my controller IP configured, it does compile and upload, and it connects to my WiFi, but then it just sits there doing "SANCHK:OK", because (I think) it doesn't know where to connect to the Vera... My Vera is configured with the IP of the gateway (192.168.1.106:5003) but it just keeps saying "Cannot Send command - Communications Error".. What am I missing?

I read that "client" mode is new.. maybe I am messing up my "MySensors" terminology, but shouldn't the 8266 need to know where to talk to Vera?

MY_CONTROLLER_IP_ADDRESS

The Vera plugin does not support client mode and must handle the connection to the ESP.8266.

So instead go to the Vera/mysensors-device/advanced tab and enter the ESPs ip number.
