Why This Happens in Real Homes

The Caseta Claro replaces a standard on-off switch with a refined paddle and Caseta compatibility. This guide wires the switch safely and pairs it to a Caseta Smart Hub. In day-to-day use, this usually looks like Caseta Smart Hub installed; Existing single-pole or 3-way switch; Neutral wire in box.

Most cases trace back to No neutral in older box; Wires mixed up during swap; Load and line reversed. The fix works best when you go step by step instead of changing multiple settings at once.

A practical order for this issue is: Kill Power -> Remove Old Switch -> Wire Claro -> Mount Switch. After each step, test the exact behavior that was failing so you can confirm what actually solved it.
