How to create a fake local sensor on Ethernet Gateway
-
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

@darkdude hi and welcome to the MySensors community.
Funny thing, @martim asked a similar question yesterday, which got me thinking.
Here is a simple example that will report the running time in seconds, once per second. So basically it will be a counter. Feedback is welcome.

Hi,
Thanks for your answer!
I combined your code with my gateway setup:

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: 192.168.1.122:5003In 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: 1I 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 fromIt'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.

@darkdude V_TEXT and S_INFO are described in the API documentation, https://www.mysensors.org/download/serial_api_20#presentation
Switch from
MyMessage msg(CHILD_ID, V_TEXT); present(CHILD_ID, S_INFO);to
MyMessage msg(CHILD_ID, V_TEMP); present(CHILD_ID, S_TEMP);to simulate a temperature sensor instead. This is shown in the temperature example.
I don't know why the sensor doesn't show up in Domoticz. I have no experience with ethernet gateway and I have never used V_TEXT/S_INFO, it could be that Domoticz handles them in a special way.
Having to add seconds++ is seriously strange. I don't have a clue why the millis function doesn't work on your device, and adding seconds++ should not work since the variable is re-initilaized each time the loop is run.

Hi,
I tried to create an ethernet gateway + one dummy sensor , like in above exemple. My controller is domoticz for windows.

Also, serial monitor gives:
Any ideas why my dummy sensor is not recognized ?
UPDATE: I managed to make above code run by removing
#define MY_CONTROLLER_IP_ADDRESS 192, 168, 0, 100Regards
