[n00b]]Ethernet GW - without NF24

hek

Currently no documentation for this branch but all the examples has been updated.

You should be able to use any one of the examples and add:

#define MY_GATEWAY_SERIAL

and remove

#define MY_RADIO_NRF24

before the MySensors.h-include.

Hello Hek, Hello Everyone,

I've actually one arduino uno and an ethernet shield Wizenet W5100 and for exemple a temp sensor DS18B20 directly connected to it.
I can send to a serial terminal the temperature value. It's working properly :-).
I would to know how I could simplify the code of the "Ethernet GW" Sketch for send the value of a sensor directly from the GW to Domoticz. (Without using an urduino dedicated to the sensor acquisition and without an RF module).

Could you give me an exemple of the code or the command to send to domoticz?
Or do you have a documentation link?
Because the link you posted before is dead https://github.com/mysensors/Arduino/tree/gateway-refactoring.

I've made many rescearch, and i don't find the protocol documentation to discuss with domoticz!

I appreciate if you could help me to the right way :-).

Awayting your answer, thanks very much in advance.

PS: Sorry for my bad english...

hek

The code has been merged into development-branch now:

https://github.com/mysensors/Arduino

brix7be

Thanks for your quickly answer.

I'm sorry but I didn't found the code or information regarde my question into the repository you noticed.

Could you please give me the complete link?

Thanks you again.

hek

We can't have all permutations of examples ready available...

So you'll have to put it together by combining:

https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/GatewayW5100/GatewayW5100.ino

and

https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/DallasTemperatureSensor/DallasTemperatureSensor.ino

You'd basically only have to copy the #defines from the gateway to the DallasTemp-sketch.

brix7be

Hi Hek,

Sure, you can't realise every solutions or exemple for everyone :-).
So it's a good advice for me to begin my tests.

When i merge the both codes, i receive an error "sendSketchInfo was not declared in this scope"!
I've checked and normally all the librairies are available for the code.
(When i'm building the GatewayW5100 only it works) but not for the dallas.

Do you have an idea?

Thanks :-).

Gwen.

hek

Just did a quick test calling sendSketchInfo in the gateway and it compiles fine for me.

brix7be

hum, strange.
I continue to search a solution.
I'll give you a feed back ;-).

Thanks

brix7be

It doesn't work.
But i found the code of Bram81 http://forum.mysensors.org/topic/1591/how-to-add-a-sensor-to-the-serial-gateway/22
and I can compile it well.
And it calls the gw.sendSketchInfo("Soil_Moist_Sensor_grb", "1.15");

Do you have another tip?

hek

remove "gw." from the call.

brix7be

You are right, it blocks when i call sendSketchInfo directly (without to be an attribute of gw) !?!

Looks like you added your own stuff..

@brix7be said:

IPAddress myIp (192, 168, 1, 100); // Configure your static ip-address here COMPILE ERROR HERE? Use Arduino IDE 1.5.7 or later!

Should simply be
#define MY_IP_ADDRESS 192, 168, 1, 100 // If this is disabled, DHCP is used to retrieve address

And what the following doing here?

// a R/W server on the port
EthernetServer server = EthernetServer(IP_PORT);
// handle to open connection
EthernetClient client = EthernetClient();

And you include <SPI.h> and <MySensor.h> twice.

brix7be

to be honnest, i don't know ...

brix7be

With the #define MY_IP_ADDRESS i can't compile the projet.
With the arduino command it works now, i can ping it on 192.168.1.100.
But still nothing in domoticz.
Am I on the right way?
thanks again :-)

I don't understand.. why do you declare ip and mac like that? It most surely isn't picked up by the library. You're probably just getting an ip from your DHCP server.

What compile error do you get when using the defines?

brix7be

i've changed as before and it won't compile.
The error is:
no matching function for call to 'EthernetClass::begin(int, int, int, int, int, int, int, int, int, int)'
No it takes the ip I put on the code before, cause the ping respond at this one.

The final goal for me is the build ethernet sensor(s) (2 or 3 one each arduino board) connected to domoticz by lan gw.

brix7be

Is there anyone who have done a sketch to connect sensor directly on an ethernet gateway ?
Iam searching a working exemple or a working draft to see the process to build my own code.
Thank everyone for your advices.

brix7be

Hi Hek, Everyone,

I've clean the approximative sketch I've made before to simply try to see the value of a DS18b20 sensor trough a serial gw in domoticz.
So i've placed the merged code below to have your advices.
In domoticz's log i can see the declaration of the gw but neither the dallas sensor!?

Does someone could check my sketch please?
To be sure that the arduino see the dallas, i've tested a sketch wich send the value to the serial terminal (it works properly :-).

Thank you in advance for your help.
Have a nice sunday all. (clouday in belgium today ;-)).
