ActiveDecora Smart WiFi Switch 15A
Leviton Decora Smart WiFi switch — no hub required.
Common Applications
Smart wall switch that replaces your existing dumb toggle or Decora switch. WiFi connected — no hub needed. Works with Alexa, Google, HomeKit. The physical paddle still works as a normal switch when WiFi is down. Requires neutral wire. The standard smart switch for North American homes.
Openness & Hackability
WiFi with cloud connectivity. Cannot flash custom firmware. But has local control — the physical switch always works even without internet. My Leviton app and cloud API are proprietary.

Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Troubleshooting
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
