merossSmart Ultrasonic Diffuser, WiFi Humidifier, Apple HomeKit Alexa Google Home SmartThings Supported, Diffuser for Home Bedroom, with LED Light, Voice/Remote Control, BPA-Free, Ultra Quiet

The media could not be loaded. I wanted a diffuser that could sync up with our home lighting , be controlled by Siri and get the house smelling nice at certain times of day etc. The diffuser works exactly as it should and has controls for both the amount of Vapor released but also the light, which can be turned off independently and a multitude of colours. It was easy to setup and has a fairly large water reservoir. The faux wood finish is reasonably discrete also

I have used this diffuser for 2 days and its fantastic. The setup was very easy just like other Meross products. I like how you can set scheduled times in which when I want it to start and end. I use Alexa so it is very helpful for me on a day to day basis. This is a quality product and it fits perfectly into the surrounding space. The diffuser has different modes high and low. I also like not having to fill it up with water every hour as the water tank is quite large.The ambient light is subtle but clearly visible. The colour can be changed from the Meross app. Overall, I would definitely recommend this product for whoever is looking for a great, stylish and modern looking diffuser for your home

Unboxing:The box it arrives in is plain, and the packaging is minimal. This suits me fine, as I dislike excess packaging, just don't expect an iPad unboxing experience! Everything expected was in the box with protective packaging around the power adaptor to stop is damaging the unit itself.Setting up:The instructions were informative and gave sufficient guidance. Some wording was a little odd such as "Do not excess the max mark in the water tank" but near enough that I could figure out what was trying to be said. Despite it saying not to overfill the water tank, there was no max marker on the unit. So very unclear what max actually means! I went with caution and used 150ml, which seems sufficient for a decent amount of time. It would be nice if they added an actual maximum water level marker.The unit itself feels very stable, and fitted together perfectly. I had it up and running within a few minutes. Compared to another similar non-smart unit i've used previously this was pretty much the same in how to set it up.Local Controls:Something that this ticks the box for is local control. One of my requirements is to always have a local non-smart element to anything smart that I get. So should my internet fail or the app cease to function the device is still usable. The LED and mist control are both managed by local buttons, so you always have complete control.Smart Features:Out of the box it is waiting to be configured, so you'll see a WiFi hotspot that it creates. You connect to this hotspot and run the application, it took a couple of attempts to connect to the hotspot, but nothing unusual from other smart devices I've used. I recommend you always configure smart devices, even if you don't want that functionality at that time, as it prevents anyone else from configuring them who shouldn't have access. The application guides you through the configuration process, and it all went quite smoothly asking me for a name and the WiFi details that it should use. It then sat at a page saying it was finalising configuration, and stayed there for quite some time before telling me something had gone wrong. As it looked like the unit had connected to the WiFi (the green LED on the front had stopped flashing) I instead restarted the app and the oil diffuser was there, although it hadn't saved the name I had given it. Also while it showed the oil diffuser there status wasn't correctly reflected within the app. Once I changed the status in the app or on the device the app correctly reflected the status of the diffuser mode and LED lighting effect. However when restarting the app it doesn't update to show the status correctly. Instead you have to set things to the status you want just in case - there is now way of telling its status remotely with any certainty. This sort of bug may get resolved in future versions though.I was able to use the app to turn the diffuser on and off, along with the LED lighting effect. The controls were very responsive with my chosen option happening near instantly. However I was a bit confused by the colour control, which didn't seem to reflect anything I did other than allow me to set it to colour cycle mode which did work. Turning the light effect on and off was simple enough, but the brightness setting seemed to have no effect. I just feel the LED lighting control could be a little clearer in the app.All controls responded rapidly when pressed in the app, and when I made a change locally on the device the status in the app updated within 2-3 seconds. So it appears that the issue is simply that it doesn't update the app when the app first loads. It says that it turns off automatically if it runs out of water, but I don't know if that will generate an alert, I'll update the review with feedback on that once I've tested that out.I know they support Alexa, Google and Apple, but I didn't connect it up to my Echo. I'd really like to integrate this with my home automation - and there is a Meross integration with Home Assistant, so I'll give that a spin. The app itself supports various automations such as scheduled on/off times and automatically turning it off after a certain duration. Sadly Meross don't offer local connectivity / integration, which means that all smart features are totally dependent upon their cloud service.In Summy:This is an attractive oil diffuser with smart features. Handy for things like making sure it turns off in the evening so it doesn't run over night, or starting it just before you get up so the place smells nice. It is perfectly functional without any smart element to it, you just get extra controls that way. Overall a solid product that could use a little bit of a software update to work out the niggles (which could well happen quickly given the nature of these types of devices).Hardware version 3.0, firmware version 3.1.5.

Having used this diffuser for a couple of days I’m very pleased with it. Setup was simple and straight forward. Plug it in, connect to it via wifi then complete setup using the Meross app, add some water and your essential oil.The app allows you to turn on the diffuser with either a high or low mist and lets you choose the ambient light colour and brightness. The difference between high and low mist doesn’t seem significant but I always use on high mist. You can also set a schedule for the diffuser to come on or go off as required. I have a Meross smart temperature and humidity sensor which allows you to automate the humidifier to come on when the humidity drops below a certain level then off once above a certain humidity.Setup with Alexa was simple. Add the Meross skill, search for new devices in the Alexa app (not always needed, more often than not Meross devices are automatically added to my Alexa after adding them in the Meross app.) and control with Alexa is enabled.The mist from the diffuser is good and essential oils seem to last well. It’s quiet enough for a bedroom at night with a faint fan noise and quiet dripping sounds, actually quite relaxing.It would be great if it was available in different finishes/colours and the high/low mist were more noticeably different. But great diffuser for the money and adds smart home functionality where many other brands which are more expensive for much the same product don’t.

Great little gadget. Connected seemlesly with the app and works really well. Just plug in..add water and some oils...good to go even if you don't use the app. App is very useful though. Can switch on or off or arrange on off times days etc. Also able to change the led colour to a stitic colour or a cycle of colours. Another bit I really liked was you change the vibrancy of the led to make dimmer or really bright to personal preference.
