Specifications are the manufacturer or retailer published figures, compiled by hand. We have not measured them, and where a figure is not published we write "Not published" rather than guess.
01
What you are actually paying for
Lutron Caseta costs more than most smart switches and asks you to buy a hub. That premium buys three specific things, and whether they are worth it depends on your house rather than on the brand's reputation.
- No neutral wire required. Many smart switches need a neutral wire in the switch box, which older homes frequently lack. Caseta is designed to work without one.
- No minimum load. Current comparisons note Caseta has no minimum wattage requirement, so it drives a couple of LED bulbs without the flicker or dead zone cheaper dimmers show - and without a bypass capacitor.
- Reliability, from a closed system. The hub talks only to Caseta devices, which is part of why the system is known for being dependable.
This page is a judgment based on those published characteristics and the system's architecture. This site does not test products.
| Lutron Caseta dimmer | Kasa KS220 | |
|---|---|---|
| Neutral wire | Not required | Required |
| Minimum load | None stated | Check against your bulbs |
| Hub | Smart Hub for app and voice | None |
| Open standard | No native Matter | Matter certified |
| Renter-friendly parts | Plug-in dimmer, Pico remote | None - wall switch only |
| Relative cost | Higher, plus the hub | Lower, no hub |
02
When it is worth it
Your switch boxes have no neutral. This is the clearest case. If the white neutral bundle is missing from the back of your switch boxes, most smart switches are simply unavailable to you, and the Caseta dimmer is the realistic option. The premium is the price of being able to have one at all.
You want dimming that behaves with LEDs. Flicker, buzzing and a dead zone at the bottom are the classic complaints when a dimmer meets a few LED bulbs. Caseta's lack of a minimum load is exactly what avoids them - the mechanism is in LED dimmer compatibility.
You want controls that stay put. The Pico remote mounts anywhere, drives up to ten devices and Lutron publishes a ten-year typical battery life. For multi-location control without rewiring, that is a genuine strength - see three-way and multi-location switching.
03
When it is not
You have neutrals and a budget. If a neutral is present, a Kasa KS220 gives Matter-certified dimming at the wall for much less and with no hub. Caseta's main advantage is neutralized - literally.
You want an open standard. The Caseta Smart Hub does not natively support Matter and has no Thread border router. If you want every device on one open standard, a Matter switch fits better - see Matter smart bulbs explained.
You rent. Caseta's wall dimmers replace a switch, which needs permission. But the ecosystem is not closed to you: the Caseta plug-in lamp dimmer and Pico remotes need no wiring at all. For a renter, that plug-in half of Caseta is the part worth buying.
The full system comparison, including where Caseta sits against Matter, Wi-Fi bulbs and plugs, is in best home lighting control systems.

01
Owners replacing a wall dimmer in an older home
Lutron Caseta Smart Dimmer Switch (no neutral required)
#ad No live price right now, so we show none. How we earn
Handles 150W of dimmable LED and, unusually, needs no neutral wire - which is the single thing that stops most smart dimmers going into an older house.
| Lumens | n/a - controls a circuit, does not light |
|---|---|
| Color temperature | n/a |
| CRI | n/a |
| Power source | Replaces a wall switch. Electrical work. |
| Dimmable | Yes - wall, app, or Pico remote |
| Renter-safe method | NOT renter-safe. Replacing a switch is an electrical alteration needing permission. |
What it gets right
- No neutral wire required, so it fits older homes where most smart dimmers will not
- 150W dimmable LED or 600W incandescent - far more than a domestic circuit needs
- The wall switch keeps working normally for anyone without the app
What it costs you
- Electrical work. In a rental this needs the landlord's agreement.
- Needs the Caseta bridge for app and voice control
- Stays with the property when you leave

02
Dimming a lamp from an app or a remote, with no wiring
Lutron Caseta Plug-In Lamp Dimmer (PD-3PCL)
#ad No live price right now, so we show none. How we earn
The smart version of the same idea: a plug-in dimmer that also answers to an app and a Pico remote, so a lamp gets scheduling and dimming without touching a wall.
| Lumens | n/a - controls a lamp, does not light |
|---|---|
| Color temperature | n/a |
| CRI | n/a |
| Power source | Plugs in between the lamp and the outlet |
| Dimmable | Yes - app, remote, or the buttons on the unit |
| Renter-safe method | Plugs in. Nothing wired, nothing fixed, fully portable. |
What it gets right
- Real dimming plus scheduling, which a plain smart plug cannot do
- Works with a Pico remote, so there is a physical control anyone can use
- Keeps whatever bulb you already chose
What it costs you
- Needs the Caseta bridge for app and voice control
- More expensive than a plain smart plug or a manual plug-in dimmer
- The bulb still has to be dimmable

03
A physical wall control that needs no wiring
Lutron Pico Remote, 3-button with raise and lower
#ad No live price right now, so we show none. How we earn
A battery remote that sticks beside the real switch and drives up to ten Caseta devices with no hub - the renter answer to smart lighting that everyone in the house can use.
| Lumens | n/a - a control, does not light |
|---|---|
| Color temperature | n/a |
| CRI | n/a |
| Power source | Battery. Lutron publishes a 10-year typical battery life. |
| Dimmable | Raise and lower on the 3-button version |
| Renter-safe method | Sits on a table or sticks to a wall with the supplied bracket. Nothing wired. |
What it gets right
- One remote controls up to ten Caseta dimmers and switches with no new wiring
- 10-year typical battery life published, so it is not a maintenance item
- Gives guests and housemates something physical to press
What it costs you
- Only controls Lutron Caseta devices - it is not a universal remote
- The wall bracket is adhesive or a screw, so it is a fixing decision
- Needs Caseta hardware on the other end to be worth anything

A neutral-wire home that wants smart switches cheaply
Kasa (TP-Link) KS220 Smart Dimmer Switch
#ad No live price right now, so we show none. How we earn
Matter-certified dimming at the wall for a fraction of the hub-based systems - the value pick, provided your switch boxes have a neutral wire.
| Lumens | n/a - controls a circuit, does not light |
|---|---|
| Color temperature | n/a |
| CRI | n/a |
| Power source | Replaces a wall switch. Requires a neutral wire. Electrical work. |
| Dimmable | Yes |
| Renter-safe method | NOT renter-safe. Replacing a switch is an electrical alteration. |
What it gets right
- Matter certified, so it is not locked to one app's future
- Dimming at the wall, which survives anybody flipping the switch
- The cheapest credible smart dimmer in current roundups
What it costs you
- Requires a neutral wire - older switch boxes frequently have none
- Hardwired, so it needs permission if you rent and generally an electrician
- Wi-Fi per switch, so a large install loads the network

FAQ
Questions people actually ask
+Is Lutron Caseta worth the money?
For owners with older wiring who want reliable dimming, generally yes - it works without a neutral wire and has no minimum load, which avoids the flicker that cheaper dimmers show with a few LEDs. For renters, or homes with neutral wires and a tight budget, cheaper options often do the job.
+Does Lutron Caseta need a neutral wire?
No, and that is its main advantage. Older switch boxes frequently have no neutral, which rules out many smart switches. Caseta is designed to work without one.
+Does Lutron Caseta work with Matter?
The Caseta Smart Hub does not natively support Matter and does not include a Thread border router. It connects to Lutron Caseta devices specifically and bridges them to Alexa, Apple Home, Google Home and others.
+Do you need the hub for Caseta?
For app control, schedules and voice assistants, yes. The switches and remotes work together locally without it, but the smart features need the Smart Hub.
+Is Caseta good for renters?
The wall dimmers are not - replacing a switch needs permission. But the Caseta plug-in lamp dimmer and Pico remotes need no wiring, so a renter can use the ecosystem for lamps.
