Support of OTA firmware updates for Z-Wave / Z-Wave Plus devices

There’s actually a Jasco employee somewhere on this forum, I forgot his name…

I got a response from Leviton regarding firmware updates:

We can send you a Z-Sticker Loaner to update your devices.

We will also provide you a return label, once your devices are updated please return the Z-Sticker Loaner.

Pretty quick response.


I haven’t gotten the Leviton update Z-stick yet but I did get the HomeSeer Z-Flash firmware update kit. It was a pain trying to set it up as a secondary controller for Smartthings, but I finally managed it (HomeSeer support was NO help).

In the ST Classic app I clicked the Plus to add devices and then clicked “Add to / Remove from Existing System” in the HomeSeer program and the Z-wave controller device was added (see 2nd image).

I updated the firmware in 6 Leviton devices to version 1.20, did a Z-Wave network repair and reset the Hub using the reset button on the back and also by disconnecting the power (and removing the batteries).

However, even though the HomeSeer flash program says the devices are ver 1.20, when I check them in the Groovy IDE, they still show the older (original) version in the raw description
e.g. zw:L type:1101 mfr:001D prod:3501 model:0001 ver:1.13 zwv:4.33 lib:03 cc:5E,85,59,86,72,70,5A,73,26,20,27,2C,2B,7A ccOut:82 role:05 ff:8600 ui:8600

Has anyone else experienced the same scenario?

Once a device is joined, the IDE won’t ever update any of the info. I experienced this when doing a Z-Wave replace of a bunch of devices to newer Z-Wave plus counterparts. You can use Z-Wave tweaker to verify the firmware from ST if you like. Whether this is just a display bug, or if there are any actual repercussions for not having the most recent device info, I have no idea and ST is silent on the issue.


But, what is a Z-wave tweaker?


Thanks again!
BTW - I just figured out how to quote a post in my reply :thinking:

I excluded a Leviton plug-in relay and the added it back in and, sure enough, now it shows ver 1.20.
Don’t really want to do that for the others because all my Smart Lighting and Alexa routines would have to be fixed.
Oh well…

You don’t need to do anything. The firmware sounds like it got updated.


Does anyone know what is the cheapest the HomeSeer zflash kit got to? Right now it’s $39.99, seems rather expensive for just a stick used to upgrade the firmware.

In November 2018 I paid $34.98 plus $4.50 shipping for a total of $39.48.

Did the replacement devices fix the LED issues you had? Was that the only issue remaining on your network?

I updated all my dz6hd to 1.2. It fixed a lot of issues, but created a new one. Very infrequent, but very annoying. Maybe once every 2 months, I have 1 switch that becomes “stuck”. And by stuck I mean, impossible to control it, whether physically or remotely (z-wave).
on/off/dimmer up/dimmer down, nothing works. The only way to bring it back to normal is a “reset”, ie power off/on. Can be done either throught the air gap or toggling the breaker.
So far 3 switches showed this issue.

I haven’t heard of anyone else encountering this however

I also get those lockups infrequently on the Leviton devices. Very annoying. I also have one switch that has stopped communicating with the hub. It’s been happening for a couple of weeks and I’ve not yet tried to resolve that issue.

i finally updated the firmware on my Leviton Z-wave switches.
Leviton loaned me a USB stick.
And sent me a link to download OTA-V12.
I wonder, is there a way to subscribe to notifications once even newer firmware gets released?


I’ll ask leviton, i contacted them via their website and we’re emailing back and forth. I’m hoping they leave me the stick as well.


Are we any closer to getting ota firmware updates?

We have the new z-wave stack now, which was a prerequisite for ota firmware updates, so we are a step closer.


As an update, a got the usbsick/hub in the mail and udated the leviton dimmers and haven’t had one disconnect in a few months now.

this is why we need zwave ota updates… bump for OTA updates…


The new Inovelli switches support OTA updates. They are planning to release firmware updates twice a year. I wouldn’t be surprised to see them more often right now since they were just released. They seem really willing to work with Smartthings to get things working.

their switches support it, but the hub they are connected to (smartthings) do not. so there is not way to update them OTA unless you get a separate z-wave controller/hub.
