Adapt your existing under cabinet kitchen lights into modern, smart kitchen cabinet lighting through Google or Alexa.
Another straggler in my smart home environment, the LED accent lighting under the cabinets in my kitchen. When the lights were first installed there was simply a switch, on and off, that’s it. The stock configuration lasted about six months. I decided to step-it-up with manual dimming functionality using a floor lamp dimming receptacle. (something like this ) Manual dimming control satisfied me for a couple of years, then I got into smart home integration and I was hooked.I looked around and surprisingly could not find solutions anywhere on the Internet, so I came up with my own way to create smart kitchen cabinet lighting. Let’s get to it!

It’s not complicated, I promise. I have implemented this in a few friends homes, and each of them had a similar configuration. Smart kitchen cabinet lighting is easy to implement!
The most expensive part you need to purchase is the dimmer (thought still relatively inexpensive on Amazon): LINK Once you buy the dimmer the rest of the parts wont cost much more. Note: If you’re just getting into smart home components I strongly recommend looking into Z-Wave hub such as smart things and use Z-Wave Dimmers . The last thing you want to do is clog up your router with 50 Wi-Fi devices causing instability. If you have more questions about this just ask in the comments… Sorry, I’ll get back on topic now.. 😀

The beauty of my proposed configuration is that it works with any type of dimmable lighting. The procedure is the same for incandescent bulbs or LEDs. On the other hand the design of this circuit also keeps the original manual switching functionality working as a backup. Your old on-off switch will continue to function in conjunction (that rhymes) with the upgrade.

The concept is to control what is typically 120 V coming from the wall into the AC to DC transformer using a smart dimmer. Here’s a brief summary on how it works:
LEDs require DC voltage, however, they are powered by your wall outlets which supply 120V AC. In-between the LEDs under your cabinets and the wall receptacle there is a transformer. The function of the transformer is to reduce the voltage from 120 VAC to the lower DC voltage required by your lights. If we reduce the voltage to the input of the transformer (using a smart dimmer) it will in-turn reduce the DC output to the lights. Reduced DC power to the lights translates to less light output. The lights are now Dimmable. Bingo!

Now that we understand the concept all we need to do is install our smart dimmer in between the wall power supply in the transformer. Once installed you can give Google or Alexa voice commands like “set the kitchen cabinet lights to 10%” or “turn the kitchen cabinet lights on/off”. It will work just like any other Google or Alexa smart light in your home.

Rather than attempt to get into more detail here, I have created a YouTube video to show you how to do it step-by-step. There is even a parts list and a description if you decide to undertake a similar project in your home.
