Some manufacturers provide new firmware versions for the public, e.g. Aeotec, but Fibaro doesn’t do this. Therefore, the firmware of Fibaro devices cannot be updated with other gateways.
Homey has no built-in function to update the firmware of Z-Wave devices (at the moment). However, Aeotec has found a way to update the firmware of Z-Wave devices with “open” firmware without having to exclude, update and re-include the devices. The problem with this would be that all flows and settings would have to be readjusted.
How it works and more info about updating the FW with a Homey can be found here:
I don’t know if a standard provision exists. It seems not really, because than Fibaro has to do it in the same way like other manufacturers.
Developer Tools can only used with a browser, more or less the same way like the WebApp and the Advanced Flows.
