What to know before buying
Listing details to confirm
Installation requires neutral wiring, 2.4 GHz Wi-Fi and a standard lighting wall box at least 2 inches deep. For 3-way or 4-way wiring, the description says to install one S515 at the LINE/HOT/LIVE location and keep the other traditional switches. Consult a qualified electrician if unfamiliar with electrical wiring. Listing details are inconsistent or unconfirmed: the product description specifies a 100–120V AC input, 15A general-use maximum and separate 600W incandescent or 150W LED limits, while the technical details list 120 volts and 600 watts without those distinctions. Customer feedback also describes mixed 4-way functionality despite the listing's 4-way compatibility claim. Confirm circuit, load and ecosystem requirements before installation.

Customer feedback reports responsive remote control and positive impressions of automation, but compatibility, app and switch functionality are mixed. Some customers report Wi-Fi connection trouble, disagreement about 4-way operation, and lights flickering after circuit energization. These concerns matter most when relying on network control or installing in a multiway circuit. The listing claims Matter and multiway support, but those claims do not resolve the reported setup and functionality differences.

- Automation and value are noted positively in the supplied feedback.
Negative themes
- Some customers report Wi-Fi connection problems and lights flickering after energizing the circuit.
