One of my Leviton DZ6HDs started acting wonky this morning (not responding to poll, it has been working fine since late 2017!) and in the course of researching the problem I discovered Leviton has indeed released firmware updates for many of its funky switches, and HomeSeer provides a firmware update tool AND has access to the Leviton firmware updates.
I really want to apply this firmware update as MANY of the problems I reported to Leviton back in November 2017 seem to be fixed by it, and other problems I’ve seen on my network MAY be a result of the Leviton switches not relaying instructions for other devices properly (also fixed!). Does Vera plan on providing firmware update tools in UI8, and equally important providing manufacturer firmware for OTA flashes? Most manufacturers will NOT release firmware updates to consumers (even though they sell their devices directly to consumers!).
For additional discussion see this thread, especially towards the bottom. One fellow got Leviton to ship him a z-stick with the new firmware and software to apply it, and another got a “loaner” from Leviton.
