Just to eliminate any possible issues after updating I did go through each device and exclude them from HE, reset each device to factory defaults and re-included it. I would use a laptop and find a central location in the house to update them. Also I did find that two of my dimmers were not found the first time, but after I updated the rest those two showed up and I was able to successfully update them. It will take a while to flash the devices so be patient. You can also flash all Dimmers/Switches of the same model at one time.

The Z-Flash software comes with the Leviton firmware hex files, so you will not need to download these. The Z-Flash will basically poll for each device and give you a listing of all devices and the current FW version. Then run the Z-flash software and it should find the USB adapter. Otherwise you can buy Homeseer's kit that includes a Z-wave/Zigbee USB adapter and you would include this device to HE and then you can update the FW. I had to force it to install, because Windows did not detect it as the correct driver, but it does work fine. You will need to manually install the driver from device manager. I have also linked the Windows driver you will need in order to use Hubitat's USB adapter. I used a Windows 10 computer, so not sure if its possible with Linux/OSX.

If you choose to use Hubitat's USB adapter you will need to shutdown the hub and insert the USB adapter into a PC.

Hubitat's USB adapter actually stores all of the Z-wave information on it, so you will not need to exclude/include any of your devices. Either way you will need HomeSeer's Z-Flash software to update them. There are two ways you can perform the upgrade, either with Hubitat's USB adapter or HomeSeer's. Where do I get the Hex files - do I need to contact Leviton or is there a download I am unable to find with searches?ĭid the z-wave stick that came with Hubitat work? Or could I use the stick that comes with HE and just get the z-flash software?Ĭould you expand on how you eventually did this please.? I have many of these dimmers and they are not working correctly with the Generic Smart Z-Wave Dimmer driver.
