Crestron CP3 Control System: Is It the Right Hub for Your Smart Home Electronics?

The Crestron CP3 3-Series Control System is a $60 used control component for shoppers building around Crestron gear and infrared-based smart-home control, including IFTTT and Amazon Alexa compatibility.

Last updated Aug 1, 2026

Choosing smart home electronics gets harder when the goal is not simply adding one connected device, but bringing audio, video, and automation controls into one setup. The Crestron CP3 3-Series Control System is aimed at that more focused role: a control component for a home entertainment arrangement with Crestron compatibility, HDMI output support, and infrared smart-home control.

Quick verdict

At USD 60.00, the Crestron CP3 makes the most sense for a shopper whose setup already centers on Crestron-compatible equipment and who wants to incorporate audio/video control with IFTTT or Amazon Alexa compatibility. Its appeal is specific rather than universal: it is built around system control, not a simple standalone smart-home accessory.

The central trade-off is condition. This Crestron CP3 is listed as used, so it suits shoppers comfortable considering a pre-owned control-system component rather than those seeking a new unit.

Who it suits

The CP3 is a natural fit for someone assembling a coordinated home entertainment environment where control of video players, cables, and adapters is part of the plan. The listed HDMI output support gives it a clear place in an audio/video-oriented setup, while its infrared protocol support points toward control of compatible equipment that uses IR commands.

It also fits shoppers who want smart-home routines to extend beyond a single remote-style control layer. IFTTT and Amazon Alexa are named as compatible smart-home platforms, which gives the CP3 a role in a voice- or automation-oriented arrangement.

It is less compelling for a buyer looking for an all-purpose smart-home device with a clearly stated plug-and-play use case. The listed details emphasize Crestron compatibility and control-system integration, so the strongest reason to choose it is a need that aligns with that ecosystem.

What stands out from the listed details

Rather than concentrating on one device category, the Crestron CP3 is described as a way to manage various audio and video devices within a home entertainment setup. That broader control focus is the key reason to consider it.

The combination of HDMI outputs and infrared protocol support is particularly relevant when a room includes both AV gear and IR-controlled components. Meanwhile, Amazon Alexa and IFTTT compatibility can matter to shoppers who want automation platforms included in the same control conversation.

Meaningful trade-offs

The CP3's strengths are tied to the kind of setup it is intended to join. Compatibility is specified for Crestron products, along with cable, adapter, and video-player use, so the appeal is clearest when those connections match the equipment already in use.

Condition is the other meaningful consideration: the unit is listed as used. For a buyer prioritizing a lower listed price for a control-system component, that may be an acceptable fit; for a buyer who specifically wants a new component, it is a practical limitation.

Choose the Crestron CP3 for a Crestron-compatible entertainment setup that can benefit from HDMI output support, infrared control, and smart-home compatibility with IFTTT and Amazon Alexa. The limitation is its listed used condition, which is an important part of the purchase decision.

Bottom line

The Crestron CP3 3-Series Control System is a focused choice for building control around compatible audio/video equipment and infrared-based smart-home functionality. Its USD 60.00 listed price and defined Crestron, HDMI, IFTTT, and Amazon Alexa positioning make it best suited to shoppers with that particular kind of setup in mind.
