Things seem to be responding very quickly and the web interface is much better than using a phone/table to configure settings. So far I've had to change a ocuple of custom divers to support a Z-wave outlet with power management. So now I can get on with the rest of the whole house transfer.
The modified Smartthings driver also seems to work but it switches the dimmers to zero when they are switched rather than leaving them at the last l (on the dashboard). The devices are now responding quickly and updating the status within seconds.
You can set the software to update the same models sequentially and leave it running. (This is painfully slow - 10 minutes or more per device and it fails if the dimmer is switched during the process). The software found the devices I had transferred and correctly identified the firmware versions and allowed me to update the dimmers.
Using the links provided above I had to download the Z-flash utility from HomeSeer and connected this as a secondary controller to my Hubitat, after installing the driver on a windows 10 PC. Using the generic "non smart" driver I could get them to function but when I tried to modify the custom device handler from Smartthings community it wouldn't work either and I was hoping to be able to use this to set some of the parameters for fade time etc. They have always functioned flawlessly and I never saw the need to change the firmware. I have about 50 of these, which I installed last year using Smartthings generic device drivers.
I emailed support and got promptly referred to this topic referencing the updated z-wave firmware for these dimmers. Unfortunately this didn't work with the Dimmers which were not reporting a physical or digital change, although the device would switch on and off and dim.
This has solved my problem - the Leviton Z-wave plus dimmers (**Models DZD6HD and DZ1KD) were being recognized by Hubitat correctly and the Generic Smart Zwave Dimmer was being applied. HomeSeer Z-Flash Kit (Includes USB Adapter) Now this is probably not needed, but I did this for more of peace of mind, all the smartapps will still exist, you would just need to re-add the device. 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.
