Quick verdict
The KS220M is TP-Link's motion-sensing Kasa dimmer: a Wi-Fi slider dimmer with a built-in PIR sensor that turns lights on when a room is occupied. It works with Google Home and Alexa and integrates locally with Home Assistant via the tplink integration. Note it is Wi-Fi only - not Matter and not HomeKit (the Matter Kasa dimmer is the KS225). A sensible pick if you want hands-free dimming on a single-pole circuit.
Standout: Motion-activated Wi-Fi dimmer from a major brand with a built-in PIR occupancy sensor.

Local control facts
Home Assistant: tplink integration, Local Polling, Platinum on the quality scale (home-assistant.io, checked Sep 10, 2026)
Why it stands out
built-in PIR motion sensor and ambient light sensor for occupancy-based lighting
smooth full-range dimming with a physical slider
well-known brand with wide retail availability
Reasons to hesitate
requires neutral wire and is single-pole only (no 3-way support)
Wi-Fi only - no Matter, Thread, or Zigbee/Z-Wave mesh benefits
no native Apple Home / HomeKit support; relies on the Kasa cloud
Best for
adding motion-activated dimming to a single-pole switch box
Kasa/TP-Link households wanting a Wi-Fi dimmer with an occupancy sensor
Avoid if
your switch box lacks a neutral wire or needs 3-way wiring
you want Matter, Apple Home, or Zigbee/Z-Wave mesh networking
Privacy and local-control notes
Wi-Fi device that pairs through the Kasa app and TP-Link cloud. Home Assistant's local tplink integration controls it locally, but the Kasa app and voice assistants route through TP-Link's cloud.
Home Assistant support: supported · integration path: tplink.
Buying reality check
Price notes: Mid-range pricing for a Wi-Fi dimmer that bundles a motion sensor. Note: if you specifically want Matter, look at the Kasa KS225 instead.
