I am having some zwave device issues after the 2026 update.

I want to make sure my zwave is the latest?

No, that’s not the latest, but that is the wrong question. It depends on how you’ve installed Z-Wave JS, because unless you are building your own you don’t control the version. Also, HA releases are unrelated to Z-Wave JS versions. The only relation is when HA requires a minimum version. Otherwise, they are independent.

See here for the most common options, as it depends on how you’ve installed Z-Wave JS (add-on, container, self-installed, etc.):

Given:

I would make a guess you are using the Z-Wave JS UI add-on. That is the latest version provided by that add-on.
