Ah the heat ... The underarms that stink, the panty that sticks, this feeling of suffocation in an overheated room ... What happiness. But since good things should not be overused, we have found a simple and effective way for you to cool off: a fan connected without blade !
But above all, why a bladeless fan ? Because the latter will allow a more stable air flow than that of the paddle fans, which themselves will stir the air. Thanks to this, the air will not tend to be warmed up (you know that the heat comes from the movement of course), although it is quite relative as felt. There is also a safety aspect to prevent children from putting their fingers at the level of the "Blades", as they are called in English. But there are still some blades, they are just in the body of the fan, and thanks to this the air flow will be directed so as to come out through the periphery of the blast zone. And thanks to this, they are normally less noisy and the feeling of air is greater at equivalent power (the air is pulsed).
There are few on the market and of varying quality. Our choice fell on the brand Earthsmart, famous for offering out of the ordinary products at an excellent price / quality ratio. Will this be the case with this wireless fan, which also doubles as a nightlight, for a price of 34 €?
Earthsmart : a fan connected without a blade for Smart Life
Contrary to the usual brand, the fan is delivered in a blue-green over-cardboard, written in Chinese, very thick. Inside is the packaging of our product in thinner, glossy cartons, with a visual of the bladeless fan, always written in Chinese. But between the two is slipped a notice in English, more or less clear. So one thing's for sure, it's not Earthsmart who manufactures this product. Let's not anticipate, but in general the quality is below what the brand usually does.
Inside, well glued in foamy slices, there is the fan connected without blade, for an micro-USB cable and Chinese leaflet. We pass quickly on the latter that we found a little too succinct. Moreover, the one in English is not left out because it does not really say how to bring the equipment into pairing mode.
The connected fan is 30 cm high, 12,5 cm wide et 9 cm thick for almost 590 grams. Not big therefore for a product of this type, which suggests average performance. But it has the advantage of being mobile because it runs on battery. The materials are of average quality, both outside and inside (hub blades, etc.).
The air will come to be sucked in by the rear of the fan and then directed towards the outlet holes on the periphery of the expulsion zone. This will react as a buffer zone and generate a less disturbed air flow than with blades. But the power is going to come from the speed and size of the inner "propellers". You can imagine that it's not going to be a Dyson.
So let's look at the features:
- Power supply : 5V, 1A
- Battery : 2500 mAh, therefore quite light
- Engime : 10W
- Range of use : 0 to 40 ° C.
Note that during this test, theThe fan was not working when unpacking. Which is quite annoying and frustrating. But since we are on a test, and we don't necessarily have the threat of a warranty that won't work, we opened it up to see what was wrong ... Having unzipped and replaced them. lugs, then manipulated the printed circuit, was enough to make it work. But this is a fairly average introduction, it must be admitted. It is noted that for the first use, it must be unlocked by pressing the button 4 times ...
In short, once this was repaired, we were able to take advantage of the strengths of this product, thanks to its 2 touch buttons:
- 6 light atmospheres : white, cold white, blue, pink, organ and light cycle.
- 4 types of blowers : light, medium, strong and natural wind. the natural wind is in fact a cycle during which the power of the air will vary in order to make like a breeze. The color of the ring around the function button will depend on the power: green, blue and white. In natural wind mode, this light will follow that of the lamp, after an orange initialization.
The colors are quite successful and well marked, even if the light cycle remains our favorite. Likewise, the breeze is quite nice, the fact of having a fluctuating air flow allowing to feel from time to time a small peak of "Freshness". But let's be frank, from 2 meters, even at maximum power, we do not feel much. It really is a desktop device.
And in this case, pay attention to the volume. At 1 meter, we have 55 to 58 dB at maximum speed. It is not huge, but it corresponds to a window open to the street. A little annoying by force. At 50 cm, it is more than 60 dB. There, we arrive at the threshold of hearing fatigue. At its lowest, we are at more than 40 dB, the recommended limit for a quality night.
Count more than 2 hours for a full charge for cordless use of approximately 1 hour 30 grand max at maximum power and with Wi-Fi (the fan will turn off at 1:05). The function button will flash red 3 times before turning off the fan and you can turn it on again, but the Wi-Fi will no longer work. A little stingy then.
It's all well and good, but you surely want to use it in a connected version, right? Let's go.
Using the bladeless fan connected with Smart Life
Here is the method we found: press the "+" at the top right, then choose " small electrical appliances and fans'. And there, we are asked to flash it. What we tried, but without success… No wonder because keeping the function button pressed starts the simulation of natural wind… We have, by default, left the fan on and proceeded with the installation. Who worked! Even if at the end, it seems that the initialization had some misfires. However, the Zemi connected fansmart appears well in connected devices and is controllable by going over it. So no problem.
In the device settings, you can rename your fan (something that was not proposed before due to the initialization bug) and then come and control it via 3 inputs:
- The power of air flow : 1, 2 or 3. To vary by pressing + or -.
- The light : no color name or colored dot to choose from, just a number, from 1 to 6, corresponding to the 6 colors. But no possibility to choose the light cycle.
- Un third parameterization not usable with this version because it corresponds to UV disinfection.
- There is also one button to turn on and off the fan
- And one last for turn the light on or off.
You also have the possibility of integrating it into routines to turn it on at certain times or when the temperature becomes too high, via a scenario. It's pretty good in principle.
Finally, this use with Smart Life does the strict minimum (light and power) but does not go beyond what is physically possible with the fan. It even does less since it is not possible to define a light cycle.
A compatible fan Alexa and Google Assistant
Le Zemi connected fansmart will go up alone on the 2 assistants as a fan, but not the associated lamp, which is however generally the case with devices with multiple functions. So that means that you will only be able to vary the fan speed and not the colors. So you have Smart Life… or your finger.
In L'application Alexa, the fan has no less than 26 vitesses… Strange for a product which has 3 in practice. But in the end, asking for a speed like this « Alexa, turn on the fan at 15 " or "at 20" will not change much because each announcement will increase by one level.
Sous Google Home, it's easier, no speed is available. So in this case, how to change them? It is not that simple but it is possible.
Indeed, under Google Assistant, but also under Alexa, you will have to ask "Turn on the fan" to switch it on or change the speed by a value. That is, by asking it once, you will turn on the fan. A second time, you will switch to speed 1. A third time, to speed 2… And to turn it off? Well it must be said "Turn on the fan" a 4th time because the sentence "Turn off the fan" is not recognized! It's impractical and totally ubiquitous (Ubu Roi, you know?).
This can be understood through the operation of Smart Life and bladeless fan. If you press the virtual button, it will turn on and turn off after a while. There is therefore no real ON status with the touch button of the fan, which will operate under pressure. The same goes for voice operation. It's too bad.
So indeed, you always have the possibility to create a scenario under Smart Life to turn it off by requesting the activation of this automation, but the use is still tedious, especially with Google Assistant.
