Hi,

Thanks for your answer!

I combined your code with my gateway setup:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * REVISION HISTORY
 * Version 1.0 - Henrik EKblad
 * Contribution by a-lurker and Anticimex,
 * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
 * Contribution by Tomas Hozza <thozza@gmail.com>
 *
 *
 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

}

I had to enable client mode (it just restarted after every loop without it). However it still does nor register as a sensor in Domoticz.
In Domoticz log there is:

2016-10-18 13:10:17.041 MySensors: connected to: 192.168.1.122:5003

In Devices i have

MySensors Gateway with LAN interface
Version: ?

Serial monitor gives:

0;255;3;0;9;Starting gateway (1
Seconds since start: 1
Seconds since start: 1
Seconds since start: 1
0;255;3;0;9;Starting gateway (R-NGA-, 2.0.0)
IP: 192.168.1.122
0;255;3;0;9;No registration required
0;255;3;0;9;Init complete, id=0, parent=0, distance=0, registration=1
Seconds since start: 1
Seconds since start: 1
Seconds since start: 1
Seconds since start: 1
Seconds since start: 1
Seconds since start: 1
Seconds since start: 1
Seconds since start: 1

I added

seconds ++

to your code and it now counts correctly but still does not register as a sensor.

Regarding a need for a "Dummy" example.

In my case here the problem is in using libraries or understanding how they work. For now it's like:

MyMessage msg(CHILD_ID, V_TEXT);

CHILD_ID - OK, it's defined allright
V_TEXT - it's not edfined in this sketch and I don't know where it comes from

It's the same with

present(CHILD_ID, S_INFO);

After finishing some basic projects I would try to define S_INFO and send sensor data there...

However after seeing a dummy sensor actually register and "work" in Domoticz I should be able to play with it for a bit, change its value and then connect a real sensor. And that should give me enough knowledge to try other sensor types.

I asked especially for a dummy temp sensor because temp sensors are easy to use, they are a basic example in many Arduino courses.

Hi,

I need some help in understanding the basics of MySensors library.

To make the long story short I'm a beginner in both programming and Arduino. In most cases I'm able to understand how things work by looking at a working example and then modyfing it to do what I want it to. However after a lot of searching and reading I still can't get what goes where in MySensors.

I want to make a thermostate based on Domoticz + Ethernet Gateway with locally attached sensors and one relay. For now I installed an example of 2.0 Ethernet Gateway that connects to Domoticz but obviously has nothing to present.

Is it possible to present a simple static value as a fake reading of a temp sensor so I can see how the message is formatted, what goes into presentation() etc. ?

I know it's all written in API section but I just don't get it.

Thanks in advance
