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

Ah. Guess I’ve never seen this issue because I’ve always set the parameters on the dimmer that control ramp rates.

I do not think the newer 14294 plus dimmer has this behavior.

Are you sure?

Yeah, I really need to keep track of the threads/links I had that detail all of this and the “explanation” from Jasco about all this. It does affect them but they have an additional parameter that allows you change to change the behaviour, the last of the 12724’s have this behaviour but in their infinite wisdom, they didn’t think it was an issue and so didn’t even give you the parameter to change that behaviour…

Sometimes I really wish I was on the firmware QA teams for everyone so I could say “no, that’s stupid, put it back the way it was”.

@Kianoosh_Karami Please add firmware update for Fibaro dimmer 2. The official DTH requires the latest firmware version. Other firmware will fail the config sync because they dont have all the parameters that the new firmware has

I am on the phone with Leviton support (only 30 minutes holding to get through). They are telling me that they are working closely with Samsung on OTA updates. They told me that update will be released in about 14 days.

I was told the the issue of device going unresponsive will be resolved once rolled out.

I was further told they they would escalate my info to tier 2 that would keep me informed as the roll out got closer. Waiting hopeful this will fix the issue I had with both ST and HE and Leviton


After waiting more than a year for something to move on this I bit the bullet and bought this HomeSeer Z-Flash Z-Wave Firmware Update Kit for $35. I was able to update the Dimmers from v1.13 and Switches from v1.15 both to v1.20.

Although the process of updating 17 devices took a few hours it was very simple to do. You do not need to exclude / include or any of that. The device is added as a secondary controller and it discovers all of your devices that it has firmware available for. It sends each one the update and then the device installs it. It’s really very transparent to SmartThings.

One thing to note is that some devices take longer than other based on the connection rate of each. Some only took 5 minutes while a few took as long as 25 minutes to update.

After the update I rebooted the hub and ran a z-wave repair as maintenance.

So far everything is working great. The remotes now report properly and so far nothing has dropped off of the network.

I wish I hadn’t waited so long to get this. I’ve only had this about 24 hours but so far I’m impressed and highly recommend it.

I hope that SmartThings does finally provide this feature for all Z-Wave devices, but I was tired of waiting to get this problem fixed. Even if they do address the problem you may still need this for any device that they don’t support. I’m planning to update my Inovelli devices next.




Hmmm, I would take the time line with a grain of salt. If they are working on it, that would require a hub firmware update, which presumably means there would be a hub firmware beta.


Yeah, there has been zero word of a firmware update that would allow Z-Wave OTA updates in the first place.

Would be great and maybe they’ll surprise us but I don’t think it’s their priority right now, unless there’s something else that requires it that might drive up priority.

I wish I had found this sooner! And right now it is on sale! Best $15 ever spent!

Once I found it I couldn’t wait, I bought the software only package, and pulled the Z-Wave stick from my Hubitat. After downloading some drivers from somewhere, rebooting windows to allow non digitally signed drivers, and installing them it worked! I recommend getting the kit and making life easier on yourself, but if your like me and have been dealing with this for months and have family coming in less then two weeks, it was worth the extra effort.


Are there available updates for Ge zwave switches?


GE are not listed, in fact the list is small,

but if you can get the HEX or HEC files you can.


I can’t seem to figure out how to do a firmware update. I connect to the smartthings hub and I see nodes that it finds in the log but nothing shows up in step 2. How do you get step 2 to populate with devices for you to update?
I appreciate any help.

What devices are you wanting to update? It may be that there is no firmware available for them.

Any news?


news for on what?

About Leviton and ST OTA FW Update.


No, but now that I have the Z-flash, I check all my device with it when I install them.

OK, Thanks :slight_smile:

Any news about OTA for Z-Wave? I would hate to buy something else to do something the hardware I have is able to do.
