Installation guide for the Satco Starfish In-Wall Wi-Fi Switch (Model S11267) — a 2.4GHz Wi-Fi smart switch, no hub required.
Installation guide for the Satco Starfish™ In-Wall Wi-Fi Switch (Model S11267) — a 2.4GHz Wi-Fi smart switch requiring no hub, rated for incandescent, CFL, LED, resistive, and motor loads.
Determine which wire is "LINE" and which is "LOAD." Your old switch may have a screw terminal of a different color (usually black) — this is either the LINE or LOAD connection. Tag this wire with electrical tape. Disconnect all wires from the old switch, ensure no wires are touching, then turn the power back on at the circuit breaker. Use a handheld voltage tester on the tagged wire: if it's "live," it's the LINE wire/box; if not, it's the LOAD wire/box (and box, in 3-way applications).
Note: Ensure power is off before performing this step. Use #12-14 AWG solid copper or copper-clad wire, stripped to 2 cm (0.8 in). Insert wires into terminal holes and secure connections by tightening terminal screws to 16 lbf-in (1.8 N·m).
A single pole or 3-way switch can be used alongside the smart switch. Important: the (existing) switch must be installed in the "LINE" wall box, and the smart switch must be installed in the "LOAD" wall box.
At the existing switch: LINE wire to one terminal, traveler wire to the other terminal, ground wire to the GND terminal.
At the smart switch: LINE wire to the AC-L terminal, LOAD wire to the LOAD terminal, traveler wire to the YL/RD terminal, neutral wire to the AC-N terminal, ground wire to the GND terminal.
| Symptom | Likely Cause |
|---|---|
| Lights are flickering | Lamp has a bad connection, or switch wire connections are not firmly secured. |
| Light does not turn ON | Circuit breaker or fuse has tripped; bulb or lamp is burned out. |
| Power indicator light does not turn ON | Neutral is not connected to switch (white wire); confirm switch is supplied from a 120V AC, 60Hz source only. |
| Intermittent switch operation | Confirm the load being controlled does not exceed 6A (720W) INC/CFL/LED/resistive, 3.6A motor. |
This device complies with Part 15 of the FCC Rules and Industry Canada license-exempt RSS standard(s). Operation is subject to two conditions: (1) this device may not cause interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, providing reasonable protection against harmful interference in a residential installation. If interference occurs, try reorienting/relocating the receiving antenna, increasing separation between equipment and receiver, connecting to an outlet on a different circuit, or consulting a dealer/technician for help.
