Review: Great product - Love this product. Not only beautiful but works extremely well. Will be purchasing another one.
Review: Instructions how to set up - How to Connect the Smart Diffuser to Alexa (Step-by-Step): 1. Download the “Tuya Smart” app (or Smart Life – either works the same) from your phone’s app store. Look for the logo with a white "T" on an orange background. 2. Plug in your diffuser and make sure it’s flashing or in pairing mode. (If it’s not flashing, hold the power button for about 5 seconds to reset it.) 3. Open the Tuya Smart app and create an account (or sign in if you already have one). 4. Tap the '+' button in the app to add a new device. Choose Small Home Appliances > Diffuser or Humidifier (Wi-Fi). 5. Connect to your Wi-Fi (must be 2.4 GHz) and follow the prompts to pair your diffuser. 6. Once it’s added, tap the settings in the Tuya app and link it to Alexa: Go to your Alexa app (already on your phone), Tap “More” > “Skills & Games” > Search “Tuya Smart”, Tap “Enable to Use” and sign in with your Tuya login to link the accounts. 7. Alexa will now discover the diffuser automatically. You can say: ➤ “Alexa, turn on my diffuser.” ➤ “Alexa, set diffuser to high.” (if it supports settings) ➤ “Alexa, turn off diffuser.” --- 🌟 My Honest Review: I absolutely love this smart diffuser! Setup was super simple once I downloaded the Tuya Smart app (that’s the one with the “T” logo). I connected it to my Alexa app on my phone with no problem. Just a couple of taps and I was able to control it hands-free. Now I can say “Alexa, turn on the diffuser,” and boom—it fills the room with the most amazing scent. I personally use Pure Essentials oils from Natural Grocers—they smell clean, fresh, and not overpowering. For me, that’s the best scent combo and where I love to shop for my oils. If you're looking for something easy, affordable, and smells amazing, I highly recommend this diffuser. It works like a charm and makes my space feel like a spa with just my voice.

## Questions & Answers

**Q: Can i use filtered water from the refrigerator?**
A: Yes you can use filtered water from the refrigerator, I use it or from my Britta

**Q: Can’t get it to be discoverable, it says to turn it off and on 3 times but it never goes into the mode**
A: I could never get mine to work either. I turned everything off that even remotely used wifi and brought the diffuser out almost next to my modem, tried multiple times exactly how the directions said and couldn't get it to connect. I sent mine back.  Good Luck.

**Q: How can you connect it to wifi.**
A: Unfortunately zi can't answer...i could never get it to connect and by the time I gave up trying, the return window had closed.  If I were you and you got this for the wifi feature, return it!  Directions are awful and the app worse...does t work.

**Q: Can it be used with just the app?**
A: Yes Use it like a normal diffuser or download the companion app to control features like LED color, mist intensity, timer settings, scheduling and more directly from your phone.

### ⭐⭐⭐⭐ Works great but wifi and app terrible
*by T***O on August 3, 2021*

The device itself works GREAT. I mean, blows away my other diffusers. The wifi and app, not so much (but will "work"). This pumps out quite a stream. My house fills with scent (farther) and in short time (faster) than all my other diffusers. Oil is going to go a long way here. Short story, i'll get another one of these for my basement and give away my other diffusers, Using less oil will pay for itself Setting this up is terrible though. I had to call their support and i/m an IT expert. Don't despair, here's what you need to know. - the instructions and the app don't match. It appears that the app is updated after product is packaged. - app is made by a 3rd party company that has no idea about the device. This all starts to make sense. - You need to download app, setup account, then go into add device ("+ sign in top right corner). This is in the instructions - whats not in the instructions is that you need to scroll alll the way to the bottom category, select "other" then select "other wifi devices" from the list, then it will go into a pairing mode. - there are two modes, they dont explain what they are. They actually use wrong terminology. - when you go into pairing, right button on device contorls on/off and wifi modes. slow pulse is "manual model". Fast is other mode. Long presss to toggle between them. Try and use fast pulse, it sans network and if unsuccessful you can choose the other mode that will let you manually find and connect to it. FYI, wifi pairing details (these details) arent in the manual. The wifi app is basic. For every schedule routine you setup (turn on at "x" time), you need to create another routine to turn it off (or stays on indefinitely). Why they dont just have a feature that lets you say "turn off after 5 minutes" is beyond me. Also, the buttons to make selections in setting up routines are terrible...you'll see. The good part of the app is if you want to just contorl it in real time (now), those buttons and controls are really good. So thankfully, i dont think i will be spending as much time scheduling things in the app as i might ad hoc (because i'll set a schedule and likely leave it). Last, it asks for permissions to bluetooth and location. This device pairs via wifi, so i cant imagine why it needs access to bluetoth (it doesn't since i didn't grant access). Also, same for location services. I imagine because the app is made by a third party that connects to what seems like hundreds of potential devices that may have these functions, it asks anyhow. You can say no, it will work. It appears to work with google home (the app), so perhaps this is where location services might be useful if you are on that platform and wish to setup a routine. Outside of this, from a security standpoint, say "no". Change it later if you need to. I do recommend this device, hopefully this review helps people save some time and hassle - and developer takes more care with instructions they provide.
