Connecting The Scent Machine Pro (Professional Unit)

The steps will be very similar to connecting the Home Unit above. Start by adding a device and allow for it to be plugged in and turned on before you start searching for diffusers to pair with.

Follow the steps presented to you in app and choose your Wi-Fi network to connect with your Pro Unit and enter your Wi-Fi password.

Once Connected you will then be able to navigate to the home screen and view your paired devices.

If you experience any issues with connecting the Pro Unit, please follow the in-app troubleshooting steps presented and try again.

Setting Up Events

Only one event is needed to run the machine, but multiple events can be edited to account for different schedules. The toggles turn the events on/off. Ultimately the setup is exactly the same aside from one difference. That difference is the selectin of intensity. Instead of a drop down you are prompted with 3 options: High, Medium, Low.

Once you select your intensity level the rest follows the same flow as the Home Unit. You then select the days you'd want this event to run on. The final step will be setting the start and end time for this schedule. Once you have all 3 steps done, you are able to then save the event and create new events for different days or occasions.

Manual Scheduling

The initial setup can be done before using the mobile app.

Press MENU to light up the screen.
The buttons:
MENU takes you to the menu or back to home screen.
ENTER confirms your changes.
UP and DOWN Change the values and move you to the next menu item.
RIGHT Selects the menu item and moves you to the right as you're entering settings.
LEFT Returns to previous screen or moves you to the left to re-enter settings.

If the machine is not scheduled to run at the current time, the home screen will display when the next Event is scheduled to come on.

Menu Categories:

Set Time/Day - for current day and time
Set Up Events - there are 5 Events. Only one is needed to run the machine. You would have multiple Events if you want the machine to run at different times on the same day, and/or at different settings on different days. For example, if you want the machine to run 9am-5pm Monday-Friday, and 9am-9pm on Saturday-Sunday, then you would use two Events:
- Event 1: start at 9am, end at 5pm, select M T W Th F as the on-days.
- Event 2: start at 9am, end at 9pm, select S S as the on-days.
Machine Info - holds information Customer Care might need to troubleshoot issues, like serial number and software version. Keep scrolling and it also shows which Wi-Fi network the machine is currently set on. If you need to change this, go to the Menu category: WiFi Reset.
Reset Events - returns all Event settings back to the default settings after you confirm "Yes". Resetting Events on the machine does NOT override the settings in the app. Setting in the app will override settings on the machine.
Reset WiFi - removes the WiFi network connection. You can enter the new WiFi connection from the app; this is done when you add the machine in the app.
