"Deprecation: Window/door is open W/2026.4 Update

I’ve looked around and don’t see any mention of this deprecation notice for the 2026.4 update.

I’ve got a bunch of these notices

I got the same, but the notification makes it easy to fix.
Should have been mentioned thogh.

This just popped up on my instance. It appears to be a deprecation due to changes in Z-Wave JS, not in Home Assistant itself.

From the Z-Wave JS changelog entry for 15.22.0 (PR link added by me):

Add a new synthetic “Opening state” variable with 3 states to represent door/window state: Closed/Open/Tilt; deprecate all old ones (#8676)

It looks like there was also some work done in HA to support this change: Core PR.

I’m glad they’re cleaning up the duplicate “door state” sensors - one of my devices has 6!

What exactly is this asking? I’ve looked at the automation for this and the only items with those names are z-wave Entities.

Is it really asking me to change the name of all these z-wave door sensors?

It’s asking you to update your dashboards and automations to use the new non-deprecated door/window entity.
