I think we need to ask Fibaro to make their firmware available to all. They are normally very good products when they get the firmware fixed but often early modules have firmware bugs.
It is not just these but many of their products have been released with small bugs that require a new firmware but unless you have a HCL, HC2 or £600 alpha release HC3 there is no way to update.
They did at one time offer a return to base update service but that is not a lot of good even to those of us that live in Europe.
