FAQs
Do I need a neutral wire for a smart light switch?
Most modern smart switches require a neutral wire to function properly. Some models offer no-neutral options, but they are less common.
Are smart switches better than smart bulbs?
Smart switches control entire circuits, meaning any bulb becomes smart. They’re ideal if you want full control without replacing multiple bulbs.
Can I install a smart switch myself?
Yes, if you're comfortable replacing standard light switches and following electrical safety guidelines. Otherwise, professional installation is recommended.
What happens if Wi-Fi goes down?
Many smart switches continue functioning manually even if the Wi-Fi is down. However, remote control and app features may be unavailable until reconnection.
Is Matter important for smart switches?
Matter compatibility future-proofs your smart home by allowing devices from different brands to work together easily. It’s a good bonus but not essential for basic control.
