Hallo to all the specialists!
I have a well running Moeller-Eaton Easy Relay home automation wit an OPC DA server.
I also use IOBroker as a controler for all my MySensors-nodes.
I looked for an software interface to connect both, but I didn't find one.
Now I decided to connect them via an Arduino Mega as an ethernet-gateaway.
So I need only a lot of outputs and inputs with two states.
I found the example-sketch "Relais Actuator", which is very helpful for such a lot of identical outputs.
But I found no way to add lines for the inputs as easy as the outputs.
I added:

#define BIN_1  31  // Arduino Digital I/O pin number for first switch (second on pin+1 etc)
#define NUMBER_OF_BIN 28 // Total number of attached switches
#define BIN_HIGH 1  // GPIO value to write to turn on attached switch
#define BIN_LOW 0 // GPIO value to write to turn off attached switch

In "void before" i added

for (int sensor=16, pin=BIN_1; sensor<=NUMBER_OF_BIN; sensor++, pin++) {
        // Then set relay pins in output mode
        pinMode(pin, INPUT);
        digitalWrite(pin, HIGH);
        // Set switch to last known state (using eeprom storage)
        digitalWrite(pin, loadState(sensor)?1 :0);
        }

in void presentation I addes

for (int sensor=16, pin=BIN_1; sensor<=NUMBER_OF_BIN; sensor++, pin++) {
        // Register all sensors to gw (they will be created as child devices)
        present(sensor, S_DOOR);
    }

The childs appear in "objects" without any state.
I have no idea, how to send the states to the controler for further use in IOBroker.
I don`t know how to create a message-container and send the states.
If anybody could help me to finish my projekt, I were very happy!

Oh, im very sorry Cant find, give me a hint please.
By the way: Very great work all about MySensors!
Thank you.

I did.
Error comes once, than for minutes no error. And now the error disappeared out of the log.
I don`t understand .
Thank you for the hint.

The MySensors Core messages (MCO) are described here = broken!?!

Here the log from debug:

From here only reading nodes.

Hallo,
I`m running this ethernet-gateway with w5100 shield on uno.
In the log of iobroker I always see this message again and again:
mysensors.0 2018-01-26 11:10:58.942 error Error for "192.168.178.133": Error: read ECONNRESET

mysensors.0 2018-01-26 11:10:54.897 error Error for "192.168.178.133": Error: read ECONNRESET
I cannot find a solution in the forum of iobroker and also nothing about it in this forum.
By the way: In the list of objects in iobroker there is always a child id 255 without any state or value.
Is it an issue ?
Perhaps of iobroker?
Any solution?

Thank You for Your quick answer.
Do I understand You correctly: I must index the BUTTOLD?
As BUTTOLD[pin) for example or how? Where?

This is a nice sketch and it is very universal for relays. Now m looking for a similar sketch for digital inputs such as buttons i.e.. I would like to join both. The problem: I want to use a mega for reading status of a lot of digital outputs (min.20) of another ISP. It is only High or Low. Only when the level changes, I want the mega send a message to the gateway. I tried this "for" loop, but it didnt help. There are too many informations sent to the gateway. I imagine a solution, where only a change at the pin will create an information, that is sent to the gateway.
Here my test, which didnt run:
void loop()
{

for (int sensor=16, pin=BIN_1; sensor<=NUMBER_OF_BIN; sensor++, pin++)
{
int BUTT;
int BUTTOLD;
BUTT =digitalRead(pin);
if (BUTT != BUTTOLD && BUTT !=0){
MyMessage msg(sensor, V_TRIPPED);
send(msg.set(BUTT ? "1" : "0"));
}
BUTTOLD = BUTT;
wait (900);
}
}
Has anybody an idea or a hint for me?

Thank You to all, who tried to help.
I think, I found the solution:
There was this line in the sketch: "const unsigned long tUpdate=60000; //update interval"
When I changed the time to 6000, it runs as when as the radio was connected.
So it was probably missing some kind of "interrupt", which usually comes from the radio , when it listens to the nodes or so?

I dont know, how to send my sketch as a file. Copy and past doesnt run.
I use an ethernet-shield and as I mentioned, when I connect and switch on the radio, everything is alrigth.

Here thr output of the seriel monitor:

0;255;3;0;9;Eth: 0;101;1;0;2;1
When I push the button in IoBroker-Vis, it takes often a lot of time until the LED is on; sometimes I have to push the button twice or more times; sometimes nothing happens at all.
When I define and connect the radio with the same sketch, it runs as expected.
