Can Smart Plugs Dim Lights?

Smart plugs have become increasingly popular in home automation, allowing users to control their appliances remotely using a smartphone or voice assistant. One question that often arises is whether smart plugs can be used to dim lights. In this article, we will explore the various perspectives and information provided on this topic to provide a comprehensive answer.

Yes, Smart Plugs Can Dim Lights

According to multiple sources, including Good Home Automation and The Verge, smart plugs with dimming capabilities do exist. These specialized, dimmable smart plugs can alter the supply voltage to control the brightness of compatible lights.

The Z-Wave Plus Smart Light Dimmer Plug is widely regarded as one of the best dimmable smart plugs available. It supports different types of bulbs, including incandescent/halogen, light-emitting diodes (LED), and some compact fluorescent lights (CFL). However, it is important to ensure that the bulb being dimmed is also capable of being dimmed, preferably not a compact fluorescent light bulb.

The Leviton Decora Smart Dimmer Plug mentioned in The Verge article is another example of a smart plug with dimming capabilities. It is specifically designed to reliably dim LED-outfitted lamps without noticeable flickering at low light levels.

No, Smart Plugs Cannot Dim Lights

On the other hand, sources such as Smart Home Point and Home Rook argue that most smart plugs do not have the ability to dim lights. They emphasize that dimming lights requires fluctuations in voltage, which smart plugs are not designed to do.

However, it is worth noting that even these sources acknowledge the existence of specialized dimmable smart plugs that can dim lights. They mention products like Insteon or Lutron smart switches as alternatives to achieve dimming control.

Special Considerations

When considering the dimming capabilities of smart plugs, it is essential to take into account a few important factors:

  • Compatibility: Not all light bulbs are dimmable. It is crucial to ensure that the bulb being dimmed is capable of being dimmed. Compact fluorescent light bulbs, in particular, are often not recommended for dimming.
  • Smart Hub Requirement: Some dimmable smart plugs require a smart hub to function properly. This is an important aspect to consider when choosing a smart plug for dimming purposes.
  • Plug Compatibility: Different smart plug models may have specific requirements in terms of plug compatibility. Some support three-pronged plugs, while others support two-pronged plugs. It is essential to check whether your lamp’s plug is compatible with the smart plug dimmer you choose.


Based on the information provided, it is clear that the answer to the question, “Can smart plugs dim lights?” is not straightforward. While most smart plugs do not have the ability to dim lights, there are specialized, dimmable smart plugs available that can achieve this functionality. The Z-Wave Plus Smart Light Dimmer Plug and the Leviton Decora Smart Dimmer Plug are examples of such products.

It is important to consider compatibility, smart hub requirements, and plug compatibility when selecting a smart plug for dimming purposes. Ensuring that the light bulb being dimmed is capable of being dimmed is also crucial.
