Z-Wave SDK Version 8.0.0 - Release Notes (Jan 22, 2026)

Any chance this will finally fix the SDK “Jammed” issues? It’s been over 4 years now! About ready to drop Zwave completely if this doesn’t fix things. Silabs’ support is atrocious. Wondering how much pull the HASS/NabuCasa crew has over getting these bugs fixed now that they’re Zwave Alliance members. I would love to hear thoughts on this from them, especially since the ZWA-2 is greatly affected by the SDK bug, as well as any Zwave device (Shelly, Zooz, etc.), many of which have the “works with home assistant” moniker.

I would like proof that Zwave truly isn’t dead!

Sorry to hear your frustration.
I only can try to cheer you up with my experience. Zwave in my house is proven to be most reliable and I have no any kind of trouble with it.
On my second system ( a friends small business, where I manage his HA system ) the experience is the same.
So for me, Zwave is freaking alive :wink:

Do you really need Z-wave 7 or 8? I think those two versions are the main problem with jams.

Using a Z-wave 5 controller should not be an issue. It’s still the most stable version there is.
