ePlus by AccuAir CONVENIENCE & CONTROL The ePlus app for your AccuAir e-LEVEL+ Air Management System provides convenience and control directly from your phone. While the ePlus app works in partnership with the hand-held remote, it also works independently, allowing you the freedom from having a secondary control source on-hand. Adjust ride height from inside or outside the car, thanks to Bluetooth® 5.0 connectivity. Plus, it’s on your phone, so it’s with you wherever you go. In a word, the ePlus app is CONVENIENT. The ePlus app gives you even greater control over existing air management system functions, as well as app-only features like, Valet Mode, System Diagnostics, and Service Routines, to name a few. System functions aside, ePlus provides three screen modes so you can choose the interface that’s right for you and your driving needs. In addition, ePlus is cross-functional with AccuAir systems that either run with or without height sensors. You want CONTROL? You’ve got it with ePlus. Have questions, concerns, or simply want more info? Contact us at support@AccuAirSystems.com or 877-247-3696. www.AccuAirSystems.com ePlus App Features: Real-Time Height Streaming Provides a live display of the percentage of suspension travel for each individual corner, along with the target height when in a preset position. This not only allows you to see exactly what your car is doing, but also provides a visual indication of RideMonitor at work. Over-the-Air Updates The ePlus app has the ability to provide over the air updates to both the e+ Connect and the Touchpad+. This capability allows AccuAir to add new features and updates to improve system performance. For example, the initial update includes patches to resolve memory corruption bugs that prevent users from saving new heights and settings. Valet Mode Setting With our new Valet Mode you now have the ability to limit the system functionality to only using position 2 and 3, with RideMonitor and Ride Height on Start forced on. This setting can only be switched on and off from the e+ mobile application. No Height Sensor Mode For those customers not running height sensors they can now turn on No Height Sensor Mode to replicate classic SwitchSpeed functionality. This setting will eliminate the height sensor error indicators on the Touchpad and default to the Manual screen on app launch. The ePlus mobile application uses a fixed time pulse for button holds to allow for a consistent pulse length when airing up. Recalibration “LITE” The Recalibration “LITE” procedure allows users to put the system back through a calibration process to improve accuracy, when making damper adjustments, or when switching pressure ranges without having to resave heights. Service Routines A new feature with the ePlus mobile application are the first two service routines to be integrated into the system, Service Mode and Compressor Force On. Service Mode disables the system entirely to allow for vehicle maintenance with ignition on while not having the air management system active. Compressor Force On will allow the user to manually turn on the compressor outputs, bypassing the pressure sensor to help in troubleshooting compressor wiring challenges. System Diagnostic To help with setting up height sensors and troubleshooting, this screen provides a live view of the system voltages (pressure sensor, height sensors, battery) while allowing manual adjustments. In addition, the system will display calibration status, the number of corners in use, as well as the state of the ignition and E-brake inputs. ECU Backlighting With the new e+ Connect featuring full RGB lighting you now have the ability to set any custom color and brightness level from your mobile device. Additionally, you can enable or disable lighting to suit your preference.

Take your vehicle’s setup to the next level with the Diode Dynamics D-Switch. This advanced 8-channel switch panel gives you full, customized control over any 12V accessory that you want to wire up. And as you might have guessed, our engineers have also tailored it specifically to be the most functional and effective controller when it comes to your lighting setup. The D-Switch features four 30A outputs and four 15A outputs, putting it solidly into the "serious" category for total power delivery, but it’s packed with all kinds of other features to customize your setup! While there are many 8-button controllers on the market, the D-Switch stands apart with a 9th button dedicated to the backlight bus bar. The backlight bus provides eight extra outputs for your accent lights, allowing you to connect all of your backlit accessories without using up any of your main outputs. With just the press of a button, you can now activate all of your backlights at once! This is a game-changer for any rig with multiple lights installed. It’s also designed to give you complete control over your vehicle’s setup with eight customizable output channels. Unlike traditional switch panels that are one-to-one, meaning Channel 1 is always tied to Button 1, the D-Switch allows you to group and configure multiple output channels per button, allowing you to control multiple outputs with a single button. You can also power a single output with the different strobing patterns that are included. For example, you can program one button to strobe a light and another to run that same light at full power. Whether you're running Diode Dynamics off-road lighting or any other 12V accessories, the D-Switch allows you to customize each button to do exactly what you need. To activate and use the D-Switch, you can use the included controller, or control it using your phone with this app! Say goodbye to switch panel apps that lag, freeze, or don’t connect. The D-Switch Bluetooth app delivers instant response and easy programming with no loading screens or connection delays for a seamless and fast experience, every time. The D-Switch includes four trigger wires, along with a dedicated Ignition wire for added flexibility. This allows you to control your whole setup using vehicle signals, for a completely integrated experience. The ignition wire can be wired into an OEM ignition source and will activate the D-Switch when the ignition is turned on. It will also shut things down when the ignition is turned off. No need to manually turn your panel off! If you want to use any outputs without the ignition turned on, no worries - you can still turn the controller on manually at any time. The three trigger wires provide seamless integration with any of your vehicle’s 12V factory signals, such as high beams, fog lights, or reverse lights. This allows you to activate your outputs automatically–no buttons or switches. With some simple programming, your entire setup can operate like it’s fully integrated on your vehicle. Lastly, the Night Mode wire can be used to activate certain outputs, such as dimming outputs, or adjusting settings for low-light conditions. This trigger also adjusts the brightness of the controller’s backlighting automatically when driving at night. Built for extreme durability, the D-Switch features a solid-state design with no mechanical relays to wear out, or physical fuses to replace. The hub is encapsulated with an aluminum heatsink, ensuring superior heat dissipation. The D-Switch is IP67-rated for weather resistance and is backed by a 3-year limited warranty, ensuring long-term reliability and performance. Whether you're off-roading or on the road, it’s built to withstand whatever you throw at it.

Verdict

The call

The clearest difference is rating: D at 3.4 against AccuAir ePlus's 3.1. D also leads on update cadence (monthly vs every 2 months). AccuAir ePlus's advantage is review sentiment (23% vs 0%) and ratings volume (45 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

D holds the better App Store score, 3.4 against 3.1. That said, the two scores are not equally well evidenced: AccuAir ePlus has 45 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 23% of AccuAir ePlus's written reviews are positive against 0% of D's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AccuAir ePlus ships an update every 2 months, D monthly. The most recent releases landed on October 5, 2026 and September 19, 2026 respectively.
