hi @Dirk_H
Great project. I'm looking for a battery powered switch sketch like yours.
Do you have it updated to MySensors v2.x? I tried to convert it but did not manage to get it working.

* DESCRIPTION
* This Program will implement six child sensors, which present one Push Button each.
* The Program is meant to be used in conjunction with the Wall Remote Hardware
* See MySensors for more information
*
* Frequency is 3.6864 MHz to ensure operation at low Voltages

/*Setup PinChange Interrupt. Unfortunately you must ensure that the "MyGateway.cpp" will not be compiled for this,
i.e. look into your Arduino libraries\MySensors folder and
---> RENAME THE "MyGateway.cpp" to e.g. "MyGateway.cpp.nolib" <---.
Of cause you must undo the renameing when you want to compile a MySensors Gateway!
The reason for this renaming is that the compilter of Arduino compiles also the MyGateway where the PinChange interrupt
Vector is also defined, which will lead to an error because it is only allowed to have it one time in the program.
