JCLOUD Smart Scent Air Machine with Cold-Air Tech for Home, Hotel Scent Diffuser, Waterless Essential Oil Diffuser 300ML, HVAC Scent Diffuser for Essential Oils for Large Room, Office, Spa

This product is actually the “Pro300” diffuser made by a Chinese company called “Crearoma Tech Limited.” They seem to specialize in designing and manufacturing nebulizing diffusers exclusively.A lot of companies will sell these diffusers under a different name (as is the case here) because Crearoma doesn't put their name anywhere on the device, in the packaging, or even in the app. It looks like they really only concern themselves with design and manufacturing, and they leave the marketing and distribution to others. Which is fine! …but it also means there are many places to buy this device online for less than what you might pay here.After a few days with it, I have to say this diffuser is kind of awesome.The instruction sheet that comes with it is definitely not awesome.So here's what I've learned.There are three ways to control this diffuser:- From the front panel- From the mobile app- From a websiteThe front panel controls are fairly straightforward, but it's far easier to program this device via the app or website. Note: You don't ever need to connect this device to your network if you don't want to. It can be controlled entirely from the front panel buttons.The app is called “Aroma-Link”. There's another app from the same company called “Smart-aroma” but that's not the right one to use.Once you've created your account within the Aroma-Link app, you can visit “aroma dash link dot com” and log in there. (Amazon doesn't allow external links) That page will let you program and control the diffuser remotely from a browser.Setting the schedule within the app is tricky. You first need to tap the “Set” button, then tap to enable each of the days of the week that you want to set, then tap the pencil icon to edit one of the 5 available programs and toggle each one on or off. Finally you have to tap “Save” and your machine is programmed.The default diffusion time is to run for 10 seconds, then pause for 110. In my home, this was just too aggressive and caused the scent to be entirely too strong. I pared it down to run 5 seconds, then pause for 180 and that seems to be a happy balance. This has the added benefit of using far less fragrance oil.There is a button marked “Fan” in the app to toggle a booster fan that only runs when the diffuser is running. I think its purpose is to disperse fragrance a little more forcefully into the room, but I haven't been able to notice a difference. In fact having the fan on makes the device just a little bit louder.For best performance, you may need to upgrade the firmware. To do this, visit the Aroma-Link website, click the “Device List” on the left navbar, then click the teal pencil icon next to your device. Scroll down to “Firmware Version” and select the latest version from the dropdown list. My device arrived with version 1.0, and as of this writing the latest is 1.2.What this device does not do is measure and report the amount of fragrance remaining in the bottle. I've been scenting my house at 5/180 for a week and have pulled the bottle out periodically to check how much liquid is left, and honestly it looks like it's at the exact same level as when I first filled it up.Hold down the Back and > buttons to factory reset the device. This will set the PIN to 1234.Tap the ^ and > buttons simultaneously to manually set the time. (If you use the app, the time will be set automatically.)Hold down the Back button to toggle the fan on or off.Hold down the Enter button to turn the device on or off.If the machine beeps 5 times for seemingly no reason at all, that means it has lost its wifi connection OR it still has a wifi connection but the main server in China went down. This happens a lot- a few times a month. It will beep one time when it reconnects or the server becomes available again. To avoid these beeps you can just use Bluetooth and never connect it to your WiFi.There doesn't seem to be a public API for this diffuser, meaning it can't (yet) be used with Home Assistant. Maybe some day!So far, so good, one week in. Hopefully this device will last a few years.

I love this! I have a very large, finished basement. Very lived in but still has a 'basement' smell to it. I'm etremely big on scents and smells and NEED my house to smell fresh and clean. THIS MACHINE DOES THAT! I even connected it to my phone and can adjust the setting from my phone. It's running 24/7 with the spraying at every 120 seconds and it's barely used the scent oil too. I thought it would run out quickly and it's barely used. The entire basement (including a little bit of our upstairs near the basement door) smells amazing!

In all honesty, I have been through countless types of essential oil diffusers and must admit that this one finally meets my expectations. I have much to say about this that is good but lets get two little details out of the way first.1. Despite advertisements saying this does not need to be cleaned (due to no need to add water), it does actually need to be cleaned. After a while it will appear to stop venting from the nozzle. But this is an easy fix. It is because the stem that goes down into the bottle of oil get a small clog once in a while. Just pull the stem off, run a wire through it to clean it and replace the stem. Done. And this will happen on average of only about once a month.2. The instructions are so very small and vague that it took forever before I realized that there is an app you can install on your phone that makes programming and operating this device waaaaay simpler than using the onboard buttons. In fact, the buttons on the device itself are more of a headache to use than the the device is even worth. Use the app.With this said, I have been through so many types of essential oil devices that I can not even count them all. None of them give you the ability to operate the device's functions in a way that this one does.Despite the fact that so many others do give you the ability to set times and/or days that the device functions, this one goes far beyond just doing this. You can also set how long each spray lasts and how long it pauses between each spray (down to the seconds). You not only can set this per individual days of the week but you can also provide different setting that you can switch to at the click of a button.For Example: You can have one setting where it sprays for 2 minutes and pauses for 2 minutes (or whatever you want) on weekdays; And also have an alternate setting where it sprays for 1 minute and pauses for 5 minutes (or whatever you want). This allows you to switch the settings to reduce usage when you are away unexpectedly.All other brands and types that I have used will need extensive cleaning often or it just doesn't provide a good result (doesn't fill the room with the sent unless you are in a small room). I have a 3 bedroom home and this device does just great by itself. Well worth the money.

So far it’s working great! Love it! Makes the entrance and living room smell delicious! It’s very quiet.
