Z-Wave Issues with Firmware Update 30.3

Jody, can you or @Kianoosh_Karami enlighten us to what the ultimate solution was?

Hi guys,

I’ve been patiently waiting for an auto firmware update of my hub to 30.4 / 30.5 as the majority of my 135 devices (mostly Fibaro) are currently inoperable.

I thought I read that this would happen 12th May but so far nothing. When can I expect an update and things to spring back into life ?


Today’s announcement:

Hub Firmware Release Notes - 0.30.5

Release Date: 12 May 2020 ~ 14 May 2020
Note that this release may be spread over a few days, so you may not see your Hub update the first day of the release period. We will post on this thread once all users should have received the update.

Many thanks @JDRoberts :slight_smile:

I can confirm that the fibaro-z-wave-fgk-101 temperature reading is working again with firmware 0.30.5!

My version of the fgk-101 is: zw:S type:2001 mfr:010F prod:0700 model:1000 ver:2.05 zwv:3.67

Thanks Jody, and all the SmartThings development team, for finally listening to our complaints.
I hope this episode has solidified enough the “Z-Wave 100% upward compatible” principle, as detailed with all its fine points by @JDRoberts, so that we will never have to fight this battle again :smiley:.

My Hub now has the new Firmware, but my Fibaro Single Switch 2 still has the same issue as above. Please send out a v0.30.6 update to fix this too :slight_smile:

I’m still having the same exact issue with my hub now on 30.5 firmware.

My Fibaro devices are humming along now without issue. Thanks for the fix.

Z-Wave Issues and Resolutions

Over the past two weeks we have experienced some issues with multi-channel Z-Wave devices that surfaced after making upgrades to the hub firmware. These issues were the result of working towards full compliance with the most current Z-Wave Alliance specification. Here is a brief summary and timeline of events.

0.30.3 Release

We released an update to comply with the current Z-Wave specification. The SmartThings hub is a single channel device. To comply, the hub must only process messages from devices that are sent to Destinatination Endpoint 0.

In accordance with the specification, after this firmware release the hub started ignoring all incoming messages from devices addressed to a non-zero destination endpoint.

0.30.4 Release

After the release, we identified a large group of multi-channel devices (e.g., Fibaro Dimmer 2) that lost compatibility as a result of 0.30.3 These devices were sending messages to Destination Endpoint 1.

To accommodate these devices, we made a change to also allow incoming messages to Destination Endpoint of 1. During the beta of 0.30.4, some devices sending messages with a Destination Endpoint of 1 were able to be patched by modifications to the DTHs and have their functionality restored.

0.30.5 Release

We learned that additional, popular Z-Wave Alliance Certified devices were not complying the latest Z-Wave specifications. The previous solution of using DTH modification would not work for these devices because they were sending messages to a Destination Endpoint that was neither 0 or 1.

Therefore, we decided to revert this change and allow all endpoints as a destination.

Looking Ahead

We have engaged with the Z-Wave Alliance and other industry stakeholders regarding this complication. We will provide updates as these discussions continue.

In the meantime, if your DTH is breaking with the specification, we urge you to change your implementation so that the device only sends updates to Destination Endpoint 0. We know many of our customers have legacy products that are not currently compatible; this is something we’re actively working to solve with industry stakeholders in order to ensure a smoother transition in the future.


Just asking out of curiosity… Were there any other low level Z-wave changes besides the multi-channel destination stuff made for this certification compliance?

We are running the newest z-wave stack with S2 support now.


@jody.albritton or @Kianoosh_Karami is S2 pairing now enabled for all V2/V3 hub users using the new app?

Should we expect a period of instability in the ZW mesh because of this? I’m having HUGE problems with random (line powered) things dropping off and needing to be re-added and/or running Repairs to get things back online… I mean if it’s just temporary instability because of something rebuilding due to the new stack, I’ll power through - but if it’s unexpected, I’ll open tickets.

I haven’t seen anything that would make me think there “should” be instability after the update. I have a mostly z-wave household and through all the versions I never had any major instability. So yes, if you are seeing major instability, open tickets.

Just ran another repair - and got my bathroom light back. If it keeps recurring, will do.

Since firmware 3.03 i have been getting these issues. Even after the 3.05 update.

So this a video of what is happening to my smartthings setup with my fibaro single switch 2 devices

@Andremain this looks like an issue with your DTH. Which DTH are you using for this? And the 3.03 firmware is the firmware of the device itself.
