Step-by-Step Solution
Confirm hardware type
Identify whether the companion switch is dumb or auxiliary and set corresponding Zooz parameter.
Audit wiring
Check line/load/traveler/common against Zooz wiring docs for your model.
Re-test state sync
Toggle from both locations and confirm hub state updates correctly each time.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Use model-specific wiring diagrams instead of generic 3-way diagrams.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
