Compared to other Logitech Harmony remotes that you set up yourself, the Harmony Pro and 2400 are a bit of an outlier in that they’re installed by certified professionals.
Between the two, the Harmony Pro 2400 is an upgrade over the Harmony Pro. In fact, it addresses the drawbacks and common issues of the latter. Basically, it has a more robust hub and more connectivity options, but that’s not all there is to it.

Design and Build
Same remote, different hub.
There’s no obvious way to tell apart the remotes of the Logitech Harmony Pro and 2400. Both have the same button layout and the same silver tips at the bottom, including the same 2.4-inch touchscreen near the top. It’s a different story when it comes to their hubs, however.
On that note, the Harmony Pro ships with the standard Harmony Hub, while the Harmony Pro 2400 comes with a beefier hub. Normally, these hubs have two 2.5mm IR ports, but the all-new hub boasts six 3.5mm IR ports. There’s even an Ethernet port in the mix, which we’ll get to in a minute.
The remotes are bundled with a charging station as standard, and by the same token, both have rechargeable lithium-ion batteries under the hood.
Performance and Connectivity
The Logitech Harmony Pro 2400 builds on the Harmony Pro in many ways.
In terms of functionality, the two are more or less similar, but needless to say, the Logitech Harmony Pro 2400 has a couple of advantages. That includes controlling up to 30 devices instead of 15 and a wider indoor radio frequency range of up to 100 ft. as opposed to 50 ft.
When it comes to connectivity, you’re limited to only Wi-Fi with the Harmony Pro, but as noted, the Harmony Pro 2400 doesn’t just have Wi-Fi but also an Ethernet port. Speaking of, the Pro 2400 Hub also features Power over Ethernet or PoE. For the uninitiated, this lets you power on the hub without an AC adapter when you connect it to a PoE router.
It doesn’t end there either. The Pro 2400 Hub also has an external antenna for better range, especially in closed-cabinet setups, and it’s detachable to boot, allowing you to reposition the antenna farther via an SMA connector. Last but not least, you can mount it on walls, and Logitech even throws in mounting screws with the package. If nothing else, all that makes it more flexible in complex setups.
Features and Usage
Both have staple features you’d expect from a Logitech Harmony remote.
The Logitech Harmony Pro and 2400 have voice control support for Amazon Alex and Google Assistant. This comes in handy whenever you need to change the channel on your TV or things like that whenever your hands are occupied. They also work with the Harmony mobile app that can convert your Android smartphone or iPhone into a remote.
Both feature Harmony Activities as well, which is arguably one of their main selling points. For the uninitiated, this lets you set a sequence of actions that can run at the tap of a button and designate a name for it. As a quick example, you can name an Activity “Watch Movies,” and when you click on it, the remote will turn on your smart TV, open Netflix, dim the lights, and lower your blinds.
Verdict
The Logitech Harmony Pro 2400 just does it better than the Harmony Pro.
Considering their features and connectivity, the Logitech Harmony Pro and 2400 are geared toward commercial clients. They’re a bit of an overkill for everyday residential installations, and they’re best left for those who own a huge house that has multiple rooms with home entertainment setups. However, if you’ve got the cash for them, they’re above and beyond the other typical do-it-yourself Harmony remotes.
Now if we had to choose here, we’d go with the Harmony Pro 2400. The price difference isn’t that big at this range, and it’s better to go all out at this point. On top of that, it remedies the shortcomings of the Harmony Pro, specifically its limited range and configurability issues.
