The Kasa Smart Dimmer Switch HS220 offers full dimming control, remote access, voice compatibility with Amazon Alexa and Google Assistant, and scheduling capabilities without requiring a hub. It supports dimmable incandescent and LED bulbs and requires a neutral wire for installation. Setup involves wiring carefully, turning off power, and configuring the device through the Kasa app.
To install the HS220, turn off power at the circuit breaker and verify with a voltage tester. Remove your old switch, identify and label wires — including neutral, ground, line (live), and load (to light fixture). Connect wires to the HS220 terminals per its guide, secure it in the wall box, restore power, and finalize setup in the Kasa app. If unsure, hire an electrician.
The HS220 supports dimmable incandescent and forward-phase dimmable LED bulbs but does not work with CFLs, fluorescent bulbs, PWM, or ELV dimming. It requires a neutral wire in the electrical box, as this is necessary to complete the switch’s circuitry and allow smart functionality.
Through the Kasa app, users can remotely adjust light brightness, create custom schedules for on/off timing, and set scenes combining multiple devices for one-tap activation. The app also allows setting minimum and maximum dimming levels to optimize performance and convenience.
Yes, the HS220 supports hands-free voice control via Amazon Alexa and Google Assistant. Users must link the Kasa account with their respective voice assistant app to enable commands such as turning lights on/off or dimming without using the app manually.
The HS220 features an on/off button for toggling lights and side buttons for increasing or decreasing brightness manually. Reset options include holding the reset button for 5 seconds to reset Wi-Fi settings or 10 seconds for a factory reset, along with a restart button to reboot the device.
Repenic offers Zigbee dimmer switches that do not require a neutral wire, unlike the HS220, which does. Repenic switches support incandescent, halogen, and dimmable LED bulbs but exclude CFL and fluorescent types, similar to HS220. Repenic models have longer Zigbee wireless range and multiple faceplate finishes yet lack compatibility with smart bulbs.
