Data Sheet Summary: In this Logitech Harmony 650 Specifications Sheet, I provide complete specifications for the product including hardware, technology, features, device compatibility, battery details, and more. Who am I and how I am qualified?  I have spent the past two years blogging about universal remotes with many of those posted focused trying to dispel the world of misinformation available online about  Harmony remotes.

Product Overview: The Logitech Harmony 650 is Logitech’s entry-level remote that lets you consolidate up to five of your remotes for other devices. It will also let you create activities and map them to buttons so that “Watch TV” will automatically turn on your TV, fire up your soundbar, turn on your cable or satellite service and even tune to your favorite station. Additional features include up to 25 programmable Favorite channels, multimedia control, and control over major video game consoles. It will not let you control smart home devices out of the box, however. It will also not work with Amazon Alexa. These require a Harmony Hub, sold separately or a Harmony Hub-based remote. However, you get a cool color LCD screen that will be envy of the other remotes on your coffee table. Oh, and the red backlit buttons also look pretty cool in the dark.

Harmony 650 Specifications: About This Chart

As part of the due diligence in preparing for our reviews on this product, we noticed that full, detailed specifications in a tabular format were not available online. While the vendor and even major review sites like CNET provide limited detail, no site provides a comprehensive level of specifications datasheet detail in a single page. Our aim is to remedy this with this new format.  Please leave us a comment below and let us know what you think. If you have thoughts for improving on this format, we would love to hear those as well.
