HomeSeer Z-Flash Z-Wave OTA Firmware Update Software with openhab2

Hello together,

did anybody allready tested this software ( HomeSeer Z-Flash Z-Wave OTA Firmware Update Software) for example with in ZME-UZB1 usb controller as secondary controller or included device?

Would that be a workaround for doing ota-updates? Heatit now published firmware updates for their devices too.
