Can't the app find your diffuser on the Nearby screen? Tap Not in the list? at the bottom and choose your model. The app will then show the same steps as below.
Important to know: a diffuser can only be connected to one phone at a time. If its light is on while this app isn't connected, another device is holding onto it. Close the Scentech app on other phones or tablets. If an old version of the app is still on another device, remove it.
Smart Aroma Diffuser
Factory reset: open the housing with the little key and press the reset button inside with a pin. Then pair it again.
Hold your phone next to the diffuser.
Tap Search again and wait 30 seconds.
Doesn't that help?
Check the Bluetooth light. If it's on while this app isn't connected, another device is holding onto it.
Turn it off and on: unplug the USB cable (or remove the batteries), wait 10 seconds and plug it back in. After a week without power: plug it in and wait 1 to 2 minutes, it will start on its own.
Smart Aroma Diffuser 2
Hold your phone next to the diffuser.
Check the Smart light. If it's on while this app isn't connected, another device is holding onto it.
Turn it off and on: unplug the adapter from the diffuser, wait 10 seconds and plug it back in. This breaks any old connection.
Tap Search again and wait 30 seconds.
Doesn't that help? The Smart Aroma Diffuser 2 has no reset button. Leave it unplugged for 2 minutes and then try again.
Smart Aroma Diffuser Pro
Factory reset: hold the on/off button for 5 seconds. Settings and schedules on the diffuser are cleared. Then pair it again.
Hold your phone next to the diffuser. The Pro has a weak signal; searching takes longer through a wall.
Tap Search again and wait 30 seconds.
Doesn't that help?
Check the Smart light. If it's on while this app isn't connected, another device is holding onto it.
Turn it off and on: press the on/off button briefly, wait 5 seconds and press it briefly again. This breaks any old connection.
Still not found?
Check that Bluetooth is switched on on your phone and that you're using the official Scentech app. If it still doesn't work after that, send us a message via chat or WhatsApp and mention your model and whether you have an iPhone or Android. In the app, under Settings › Help, you can tap Copy diagnostics and paste that into your message; this helps us see what's going on more quickly.
