It is possible to update the firmware in LHC5028 by means of "Over The Air" (OTA) device update. That means it is not required to connect these devices to a controller or a PC via cable. The firmware, in the device, can be updated directly over the Z-Wave wireless system.
The firmware files that can be downloaded from here has file extension .OTZ, in some controllers it is required that files must have file extension .HEX, in these cases, the file can just be renamed - the firmware file is a hexfile.
Firmware version 0.7 (Not Z-Wave Plus certified):
In firmware version 0.7 are the inputs able to control the outputs directly. The standard configuration is that the inputs control the outputs and the inputs are now edge triggered - so that each activation of an input will the toggle the on/off status of the input. This new default behaviour of the module means, that the module now - out of the box - will function as a stepping relay (danish: kip-relæ).
NB. When doing an update of the firmware in LHC5028 to version 0.7 it will loose its network information and will require re-inclusion!
