What kind of data? If you want to send light levels the Serial Protocol support V_LIGHT_LEVEL for raw values.
Otherwise... well you can send any number you want via a V_LEVEL as long as you know what to do with it on the controller side.
Arduino code on how to send data is part of most examples on this page.
@bjacobse Yes, wdt business can be quite confusing
Optiboot has a sophisticated wdt approach: wdt is only enabled if the MCU is reset externally (this is the case when you upload a new sketch from the IDE), in all other reset cases (i.e. watchdog-, brownout- and power-on reset), the wdt is disabled and optiboot directly hands over to the sketch.
See here for the conditions: https://github.com/Optiboot/optiboot/blob/master/optiboot/bootloaders/optiboot/optiboot.c#L484-L485
And here it gets disabled:
https://github.com/Optiboot/optiboot/blob/master/optiboot/bootloaders/optiboot/optiboot.c#L847
This also means that with optiboot, wdt is always disabled when the sketch starts (if WDON fuse is unset).
And to give a heads up for the MYSBootloader 1.3 release: wdt will be on by default (at the moment 4s), and the user has to either disable or reset it in the sketch. This is a safety mechanism and the only way to remotely recover from a bad/faulty FW.
@Joe13, I am new to DzVents too ... but it is a great opportunity to learn
Have a look into the Domoticz installation folder, can't remember now exactly where but there is a sub-folder with interesting examples, when you start reading these examples you may have a better overall understanding of how DzVents works.
Their wiki is also very usefull:

Have fun @Joe13 ...
I think I understand what is happening.
The compiler compiles all source files it finds in the folder. So when compiling the sketch itself everything goes fine I think. When the compiler comes across the MyTinySensors.cpp, it tries to compile that file also but can't find the define MY_NODE_ID.
So I think you should move these files to subfolders (like done in the MySensors structure), so they won't be compiled individually anymore. Sounds plausible right?
