Why is the diffuser on but not spraying, or why is there no scent?
This diffuser only works when the app schedule is set correctly and the current time is included in the selected Mode. Power / Running Status must also be on. Eg, if it is Monday 5 PM but the Mode only runs until 4 PM, it may stay on but not spray.
Why was the scent strong at first, then became weak, or why is it noisy but not diffusing well?
This is usually caused by oil residue buildup in the nozzle, filter, or bottle parts. Oil thickness and concentration can also affect performance. For example, after a few weeks, the diffuser may still run but smell much weaker.
How do I adjust scent strength in the app, and what do Low / Medium / High mean?
Scent strength is adjusted in Modes by changing Spray Duration and Pause Interval. Longer spray and shorter pause make the scent stronger. Low / Medium / High on the home page usually show oil level, not scent strength.
What oil can I use, do I need to add water, and what do the light colors mean?
Use pure essential oils or diffuser-compatible fragrance oils only. Do not add water, and avoid very thick oils or carrier oils. The light colors show oil level: red = low, yellow = medium, green = high.
What should I do if Bluetooth won’t connect, or if parts are missing or damaged?
Make sure the diffuser is powered on, Bluetooth is enabled, and search again in the correct app while staying close to the unit. If any part is missing or damaged, please con-tact us through Amazon message for replacement support.
