Kasa Smart Dimmer Switch HS220P3, Single Pole, Needs Neutral Wire, 2.4GHz Wi-Fi Light Switch Works with Alexa and Google Home, UL…

The TP-Link Kasa HS220P3 has the most overwhelming retailer signal in this entire pool: a 4.6-star average across nearly 35,000 Amazon ratings, sold here as a three-pack that drives the per-switch price well below the Lutron options. Across those verified-purchase reviewers, the recurring praise is straightforward setup over 2.4GHz Wi-Fi with no hub required, dependable Alexa and Google Home control, and strong value when wiring multiple rooms at once.

The consistent limitation reviewers raise is that the Kasa requires a neutral wire, which rules it out for some older installations, and it lacks Apple Home support that the Lutron and newer Matter-based models offer. As a Wi-Fi device it also depends on a solid network rather than a dedicated low-power radio. No independent lab or specialist-community data appeared in the supplied signals, so this synthesis is built on the very large body of retailer reviews; that volume is a meaningful trust input, but Amazon ratings are gameable, so we weight it as strong corroboration rather than a verdict. For shoppers prioritizing price and no-hub simplicity, the consensus is clearly positive.
