App Setup & Smart Controls

Yes, you can absolutely do that. If you're someone who prefers keeping things off the grid or just doesn't want another app on your phone, you're totally covered.

The kevinleo machine comes with a built-in display screen and physical buttons directly on the device. You can manually program everything right there on the hardware—including setting up your work schedules, customizing the mist intensity, and turning it on or off.

Going manual means you don't need Wi-Fi, Bluetooth, or a smartphone to get the machine up and running. The app is basically just a convenient remote control, but the screen on the device gives you full standalone mastery.

Let me know if you need a quick rundown on how to navigate the screen menu!

Yes, you absolutely can! The Grouping feature in Scent Tech is a lifesaver for business managers.

If you operate a hotel, retail franchise, or a large multi-story home, you don't need to configure every machine individually.

How to use Group Control:

1. Go to the app home screen and locate the "Device Group" function.

2. Create custom group names based on your layout (e.g., "1st Floor Retail" or "Spa Treatment Rooms").

3. Move your paired machines into their respective groups. Now you can batch-adjust data (like setting all machines to 30s ON / 90s OFF for the weekend) with one single click!

Programming your automated scent calendar is the best feature of the Scent Tech app! Let's get your scheduling optimized.

The app allows you to customize up to 5 independent working periods per day. However, the microchip inside will ignore instructions if your event times overlap. 

The Pro-Scheduling Formula:

• Never Cross Midnight in One Event: If you want it to run from 9 PM to 2 AM, entering 21:00 to 02:00 in Event 1 will cause a logic error. Instead, do this:

  • Event 1: 21:00 - 23:59 (Select Mon-Sun)

  • Event 2: 00:00 - 02:00 (Select Mon-Sun)

Don't panic! Your hardware is completely fine—this is almost always a mobile OS permission issue. 🔒

When you first download the Scent Tech App, modern smartphones (especially iOS 15+ and Android 13+) prompt you for permissions. If you decline even one, the app becomes blind.

Follow this quick 3-step checklist:

• The Location Permission Trap: On Android and iOS, the app requires "Location Services / Precise Location" permissions to be enabled alongside Bluetooth. Why? The OS groups Bluetooth LE (Low Energy) scanning under location privacy. Go to your phone's Settings -> Scent Tech -> Enable Bluetooth & Location (Always or While Using). 

• Distance Check: Bluetooth LE has an effective pairing range of under 15 feet (5 meters). Move closer to the machine during the initial sync. 

• Hard Reset: If the pairing signal freezes, unplug the power adapter from the back of the diffuser for 10 seconds, plug it back in, and tap refresh in the app

Hey tech lovers! Welcome to the smart hub.

We hear you! A few users have reported that after adding their diffuser via Wi-Fi, the device seemingly "vanishes" from the app list upon reopening. This is typically a cloud data synchronization latency or an IP lease issue with your router.

Here is the quick fix to lock your device in permanently:

1. The 2.4 GHz Network Rule: Like 95% of smart home appliances, the Wi-Fi module inside the scent machine strictly supports 2.4 GHz Wi-Fi frequencies, not 5 GHz. If your router has "Smart Connect" (combined 2.4G/5G under one name), please split them in your router settings and connect your phone to the 2.4 GHz channel during setup. 

2. Account Sync: Ensure you are fully registered and logged in via email/phone within the Scent Tech App rather than running as a temporary local guest. Account login forces cloud data backup to prevent device info drops. 

3. The Wi-Fi…
