Buying Guide: Key Purchase Considerations
- Neutral wire requirement: All five options in this guide state neutral wiring. Confirm your wall box has a neutral conductor before purchasing.
- Wi‑Fi frequency: All products specify 2.4GHz; ensure your router supports a stable 2.4GHz network for best compatibility.
- Voice control ecosystem: Each product lists Alexa and/or Google Assistant support. If you use HomeKit, verify which models provide native support or plan for a workaround.
- 3‑way vs. single‑pole use: Some models can function as both single‑pole and 3‑way. Choose based on your current wiring and desired control points.
- Compatibility with hubs and platforms: Matter certification (TP‑Link model) expands compatibility, but confirm your preferred platform integration and any device limitations (bulbs, fans, etc.).
- Dimming capability: If you need dimming, prefer the KS230 dimmer kit or similar options; not all 3‑way switches include dimming.
- Installation and safety: App‑guided setup helps, but electrical work can be hazardous. If unsure, consult a qualified electrician for wiring tasks especially for 3‑way configurations.
