Prime Day discounts are not limited to stand-alone products. There are also bundle offers, especially on smart home devices that work together. [For example, Amazon is offering an Echo Dot and Lifx WiFi smart bulb package for $18. The Echo Dot is usually $49.99 and the Lifx bulbs can cost $25 or more depending on the color profile. In other words, you can get both a reliable smart speaker and a great smart bulb for less than the price of just one.

This pack makes it simple and easy to start using smart home devices; Lifx makes some of the best smart bulbs that can be integrated with virtually any smart home system. We also appreciate that the Lifx app offers a wealth of scheduling options.

However, Lifx bulbs can be controlled using Alexa instead of the Lifx app; if an Echo Dot is within range, you can have the speaker's built-in voice assistant turn the lights on and off whenever you want.

The Amazon Echo Dot (3rd generation) is being displaced by the newer Amazon Echo Dot, but there are no major differences other than appearance. The existing Echo Dot remains a very good speaker for its size, and its fabric-covered exterior is easy on the eyes.
