Kasa dimmer switch HS220
Product description
Technical details
For a room with a compatible single-pole light circuit, the Kasa HS220 combines LED dimming with app and voice control. Its brightness range runs from 0% to 100%, with adjustments available at the switch or in the Kasa app. You can also set schedules or control the lights remotely through the app.
It requires a neutral wire, a 2.4 GHz Wi-Fi connection and a standard lighting wall box at least 2 inches deep. The listing also states that the switch is UL certified and includes a 2-year warranty and free 24/7 technical support.
What it works with
The HS220 is designed for single-pole setups, not 3-way circuits. If one light is controlled from two locations, this model isn’t the right fit, the product information points to TP-Link’s HS210 KIT for that setup. It works with LED lights and supports voice control through amazon Alexa or Google Assistant. The Kasa app adds control when you’re away from home, as well as scheduling.
That mix is useful if you want more than a basic wall dimmer: for instance, set a softer light to come on in the morning, or dim a child’s room from the switch or app at bedtime. A conventional dimmer may be a simpler choice if you don’t need Wi-Fi, schedules or voice commands.
Usage tips
The app’s guided instructions walk through installation step by step, which may help if switch wiring feels unfamiliar. Still, the existing wiring and wall box have to meet the requirements, app guidance doesn’t make a single-pole switch suitable for a different circuit. If you’re unsure what wiring is present, get qualified help before starting.
Once installed, use the switch button or app to choose brightness. The product description also notes a one-click fade-on and double-click fade-off function, which can be handy when you want a gentler change in a room. Scheduling and remote control depend on the required Wi-Fi connection being available.
Buying questions
Can I use the HS220 in a 3-way setup?
No. It’s for single-pole setups only. The product information names the HS210 KIT as the option for a 3-way arrangement.
What should I check in the wall box?
The circuit needs a neutral wire, and the standard lighting box must be at least 2 inches deep. The switch also requires 2.4 GHz Wi-Fi to work.
Can I dim the lights without using the app?
Yes. Brightness can be adjusted with the switch button as well as in the Kasa app. Voice control is also supported through Alexa and Google Assistant.
Before you buy
It may suit you if you have a single-pole LED lighting circuit and want dimming alongside app scheduling or voice control. It may not be the best choice if your light is wired as a 3-way setup, your box lacks the required depth, or there’s no neutral wire. Those installation details matter more than the smart features: confirm the circuit type and wiring first, then decide whether remote access and schedules are worth adding over a basic dimmer.
