[n00b]]Ethernet GW - without NF24

brix7be

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.

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 ;-)).

No idea?

Sensors attached to gateway (node id=0) is a new feature.
Might be Domoticz filtering these type of messages perhaps?

@GizMoCuz might know if this is the case.

Hello,
I have created ethernet gateway :) with 2 sensors :) (DHT11, and door/windows sensor) all data are send to domoticz without problem.But when i adds "przekaznik" - one channel relay - i can't send/receive data about this relay. Can anyone check why ?

sorry for mess in code

Just did some verification of message receiving in gateway on the ESP8266 sent from my shell (using netcat). Messages is showing up in receive() just fine here.

Are you sending to node 0 from Domoticz? What does the log say in the gateway?

Nothing special

I'm receiving only this kind of information.

How can i send "0" from domoticz to GW ?

hek

Your have messed up the presentation of your S_LIGHT devices in the loop. They start with id 1 in the loop. But that id has already been used by CHILD_ID_TEMP.

afick

Even if i change CHILD_ID_RELAY (to 5 or 6 ) sill the same.

zaphodus

I had the same problem as you and I have found a possible solution. The arduino has default auto reset on serial connection. So when you connect gateway to controller trough USB, the gateway is rebooting immediately and processing presentation(). In case of wireless gateway (esp8266) this does not happen. The presentation() runs only on startup of the gateway. I made little change in MyGatewayTransportEthernet.cpp and now the gateway processes presentation() when the controller is connecting to it.

You can find here my solution:
