Story is straight but out of context. We can only do it upon device manufacturer request, and why not, even of users request, if coincides with a case where this is a known issue already discussed with the manufacturer of the particular device.
This is done through the cloud, (the file is pulled by Vera from the manufacturer server or our own server), and passed to the z-wave device on nightly heal.
Why this ?
1.probably because the device manufacturers also offer an option to do this, either paid through an additional "Z-wave dongle", or free through the proprietary gateways, or even direct replacement.
2. Liability reasons, in case something goes wrong with that device.
