Amazon Echo costs just under 180 euros, Amazon Echo Dot just under 60 euros. Despite the large price difference, the functions of the two devices are very similar. We’ll show you which smart speakers are really worth it.

After only two weeks with Amazon Echo, it’s hard to imagine our household without this device. And that means something. Because my wife is usually sceptical about the new smart home technology that I regularly bring along. Also because many things are unnecessarily complicated and rarely function reliably.

Not so Alexa. The smart Amazon language assistant is the heart and brain of both Echo versions. Her big advantage over many other smart home solutions is that she listens to the word right after the simple installation – both with Amazon Echo and Amazon Echo Dot.


Both versions with impeccable speech recognition

Both versions feature seven microphones that reliably detect the direction of speech and use the other microphones to achieve a kind of noise cancelling.

The code word “Alexa”, which starts the speech recording, was only accidentally triggered twice during the two weeks of use. Who perhaps listens to the name Alex could get more problems with it. In this case Amazon Echo and Amazon Echo Dot alternatively offer the trigger words “Amazon” and “Echo”.

When two or more people talk at the same time, Echo no longer understands his trigger word. Also Amazon Echo (but not Amazon Echo Dot because of the smaller speaker) gets problems if it plays music too loud.
In our household there is an Amazon Echo in the living room and a small Amazon Echo Dot in the bedroom. The biggest difference between the two: The speaker in the Amazon Echo is much better than the one in the Amazon Echo Dot.

Main use of the Amazon Echo in the living room: The playback of music via the integrated music service Amazon Prime Music and the linked Spotify account. In most cases, this works excellently.

But what bothers me enormously is the sound quality of the Amazon Echo. Don’t get me wrong, it’s anything but grottig bad, comes close to a good Bluetooth box like the UE Megaboom (click here for a test). However, it can’t even come close to replacing a reasonable system.

We use Sonos at home. It was already announced in April that in 2017 there will be a deep integration of Sonos into Amazon Echo. From then on Amazon Echo will be able to control its own Sonos system directly.

Until then, Amazon Echo owners will not be able to control external speakers of any kind. Not so with the much cheaper Amazon Echo Dot, which has a jack output for audio signals. The audio signal can be fed directly into the Sonos system via a Play:5, but any other commercially available music system can also be controlled in this way. The Amazon Echo Dot can even be used to control Bluetooth speakers.

This gives Amazon Echo Dot a decisive advantage over Amazon Echo. Even if you order loudspeakers for 20 Euro in addition to the Amazon Echo purchase price, it is still 100 Euro cheaper and offers absolutely the same range of functions.

Inirv React prevents you from leaving the gas open

Did I turn off the gas when I left home this morning? Is the door properly closed? Are the lights off? Questions we all asked ourselves one day. Thanks to Inirv React, you may soon no longer need to ask yourself first. A project currently being financed on Kickstarter will allow you to control the gas from your phone. Practical and reassuring at the same time, a new step in the development of the connected kitchen. We explain the details to you.

Inirv React, the reassuring system

You’re sure of that. It’s closed. It’s a mechanical gesture you never forget to make, right? But there’s this haunting doubt lying around in a corner of your mind. What if your house goes up in flames because you forgot to do it today? The idea of Inirv React was born to respond to this fear.

The system consists of a sensor and 4 control buttons. The sensor is equipped with smoke and gas detectors and allows the buttons to be connected to Wi-Fi. It connects to them via Bluetooth, allowing you to control the system from anywhere. In case of a problem or danger, an alert is sent to you in real time. Inirv React buttons can replace those you already have or be added to existing ones.

Controlling the gas through an application

The buttons have a small motor that allows you to activate them remotely and therefore close the gas if your application tells you that you have left it open. A small LED, which is not without reminding you of the flames, also indicates the power level. Finally, thanks to the motion detector, if the kitchen is empty for more than 15 minutes, the gas is automatically shut off.

The unit is powered by a rechargeable battery system and can be adapted to almost any gas cooker. You can also choose a specific color to make it fit in with your kitchen. Inirv React will also be compatible with Alexa, Amazon’s personal assistant.

The project is still in the financing stage on Kickstarter. You have until February 15 to support it. Just over $125,000 has been raised so far, but its creators are targeting the $400,000 to unlock all the features. Small problem, the first level of donation is no longer available so if you want to collaborate, you will have to pay at least $229. For this price, you will be entitled to 4 controllers. It’s up to you. But the system will clearly cost you less than buying a connected furnace with an equivalent system.

Aqara vibration sensor

Hello friends

Today I want to talk about a new gadget for the system of smart home from Xiaomi – A vibration sensor from the brand Aqara, known to every builder of smart home.

aqara vibration sensor


I’ll start as always with the box. It is unusually large for such devices. Framed in the traditions of the genre, except that the list of parameters of the Aqara vibration sensor moved from the back side of the box to one of the ends. The sensor works on the ZigBee protocol, has an autonomous power supply on the element CR2032 and size 36 * 36 * 9 mm.

There is a lot of empty space in such a big box, I don’t know why they did it. But a dozen of these sensors would be easily entered into it.

In addition to the sensor-included a spare sticker double-sided tape and instruction, and multilingual-is present even in the Russian language.

The appearance of the sensor has a traditional for Aqara gadgets, square shape and appearance. Moreover, it is exactly the same as the temperature, humidity and pressure sensor, excluding markings and no openings to measure the relative humidity.

On the frontal surface there is a marking in the form of two wavy lines, and a blue led.
At the top end of the sensor is the pairing button with the gateway.

Behind-a cover, with already pasted bilateral tape under which there is a 3 volt battery CR2032.


The sensor plugs into the Aqara application directly or through the gateway plug-in. Connection Wizard Standard-Select the desired sensor from the list, press and hold the sensor button to 3 flashes of diode and select the room in which the sensor will be.

The sensor plug-in has a standard two windows-in one of them the list of scenarios in which the sensor is involved, in another-a log of positives. Everything else is on the menu

From the exclusive-in the menu of the sensor there is statistics on the curve of vibration, apparently in the context of the day and the week, the data is not updated yet, and their meaning is incomprehensible to me. There is also a configurable level of sensitivity, the default is medium. If you need to change-it is better to select it experimentally depending on the tasks, then after selecting the level, you need to press the button on the sensor and get a voice confirmation from the gateway.


The sensor, of course, can only be used as a scenario condition. It offers three exposure options — vibration, throw, and tilt detection. In the logs, these actions are displayed, respectively, as object is touched, object drops, and Tilt detected. Experimentally I have established that the first action-detection of vibration, can not be more often than once in a minute, the second and third-as the action is committed.

What do all these actions mean?

The event is a vibration detection, generated as I said no more times in 1 minute, for it is necessary, as the name implies, the impact of vibration. For example, the sensor is in the closet, when closed the doors or window, it caused vibration. Or it is on some object which has been shifted, on a safe a door which has opened and closed, on a chair on which have sat and so on.

The throw event is generated when a similar fall or throw is in motion. Use cases-to track the fall of some items, or for example, sharp closures of caps.

Tilt, or rather say offset, is the action that will be generated when the sensor is docked on a door or window and that will move. Unlike the open sensor — which generates statuses — open or closed, the vibration sensor generates precisely the movement of the window or door, can be useful in cases where the door in principle is not closed, or is sliding or rotating.

The use of such a sensor-I think a lot, and now you can decide whether you need it or not, and for what, personally for yourself, I still see two cases-a movement of doors that are not always closed, and working surface vibration when opening/closing the door The safe is for the illumination automation.

Home automation lessons: 6 tips to secure your home

Every year, hundreds of thousands of burglaries are recorded. To limit the risks, the technical people through the lesson of home automation, gives you some advice to secure your home. Apartment, pavilion or large house, there are simple solutions to repel burglars.


Getting a home automation box

Thanks to connected technology, it is possible to live safely at home. The home automation will be the “brain” of your home, the mainframe. It will allow you to manage all your accessories and create scenarios allowing you to protect your home from possible intrusions. Thus, if an intrusion is detected, rather than directly triggering the alarm that may disturb the neighborhood, you can simulate a presence. If the system detects that someone has entered your property, you can start by turning on your lights at home, or turn on the Hifi rf wireless system, etc.

Choose different sensors

If you live in an apartment, we recommend you install at least an opening detector and a motion detector with a remote control and an indoor siren. These installations correspond to the basic security package.


If you live in a house more or less large, you will have to adjust the number of accessories according to its configuration, the number of accesses and also the number of rooms but especially you will have to add an outdoor long range wireless relay motion detector. Coupled with an external siren, this device can prevent a malicious person from entering your home.” For example, if you have a yard, you will put your outdoor motion detector in it. The burglar will sound your alarm even before he enters your home, this detector is animal compatible. That is, it is configured so that only people passages are detected.


For optimal service, thanks to the automation system, it is possible to “cross zones”. By coupling a door detector with a motion detector in the same room, if the door opens due to an air current for example, the alarm will not be triggered because no movement in the room has been detected. This limits false alarms that can also bother your neighbors.

Install IP cameras

The IP cameras let you keep an eye on your home wherever you are with your smart phone, tablet or computer. So, as soon as you received an alert, you can directly connect to the application to see what is happening at home and check that it is really an intrusion either by email or by push notification (new interface). The IP camera can also take photos that will be sent to you with the alert email.

The utility of a battery alarm

An alarm system is only effective if it is properly powered. In addition to the use of household electricity, there are also batteries and accumulators that can power the alarm system. Focus on battery alarms.


Functional, reliable and very practical alarm system

Power cuts or voltage drops are sometimes unavoidable. It can also happen that the criminals cut off the power supply to deactivate an alarm system. This is precisely the great advantage of battery-powered alarm rf wireless systems. Also known as a “wireless alarm”, this type of alarm system operates independently of household electrical current. In the event of a power failure, the alarm system remains functional. Even more interesting, the battery alarm system is easy to install and maintain. We can therefore do without the intervention of professionals, especially if we are a little handyman. The batteries used are often specific, but some models simply use alkaline batteries. These alarm power sources are designed to last. Their autonomy can go up to three years.

Alarm system and solar energy

Some alarm models are powered by both household electricity and a battery. The latter is recharged by electricity and in the event of a power cut or drop, the lithium battery or batteries automatically take over. It is from this idea that solar energy alarm long range wireless switch system was d for an outdoor alarm system, this type of alarm can also be installed indoors. Like battery alarms, solar powered alarms are also autonomous and reliable. With the solar energy captured by the photovoltaic panel, the batteries are continuously charged and the alarm system remains functional. This type of alarm is also easy to install and maintenance costs are very low.

Overview on the roller shutter with wall switch



You wish to hide yourself from the prying eyes of neighbors and passers-by while letting the air circulate in a room of the house? It is best to equip your windows and doors with roller shutters with wall switches.


Why choose a roller shutter with wall switch?

At first glance, the motorized roller shutter increases the safety of your home. It adds strength to your windows and doors that allow them to resist any intrusion. Moreover, thanks to its automation, the roller shutter closes without leaving any chance to the thieves. In addition, the electric model is more practical during handling since it opens without you having to make any great physical effort.


The roller shutter drive with wall remote control switch is recommended for various reasons. The wall control can be more practical since only one tool is needed to close and open all your roller shutters. This also saves time. In addition, it is easy to use since simply pressing the ON/OFF switch allows you to remotely control your electric shutters. In addition, the wall switch is installed in a fixed location. This prevents you from misjudging the location of your control system.


Choosing a roller shutter with wall switch

The roller shutter with wall switch fits all types of entrance doors and windows, whether PVC or aluminum. Nevertheless, the choice of motor for your roller shutters is important, because its power depends on the size of your equipment. Before investing in such equipment, take the time to measure the size and weight of your shutter. If you ever combine a less powerful automated system with a shutter that is too heavy, you risk damaging your motorization and ruining your comfort. On this question, it is best to refer to the manual that indicates the weight that an automated long range wireless switch system can support. The choice of your wired motor for roller shutter must then retain all your attention.

Garage door operator controls: switch or remote control?

The garage door operator is particularly interesting because it does not need to be operated manually at the time of opening or closing. Such a task can be difficult in the long run. With an automatism, this mechanism becomes automatic, which greatly facilitates the task. It can be triggered remotely and here you will have to choose between a switch and a remote control. Focus on the advantages and disadvantages of each of these garage door operator controls.

The advantages and disadvantages of a garage door switch

The garage door switch generally has the same shape as all other types of switches. The only difference is that it is designed to open or close a motorized garage door. This already provides excellent comfort for users who no longer need to operate it manually morning and evening. The switch is fixed only a few meters from the radio control system. It is connected to it by means of an electrical wire and the installation is generally simple and quick to carry out. In practice, simply connect the cable already supplied with the unit’s motor. Other key advantages of the garage door operator switch include its exceptional strength and durability. Not to mention the fact that it is an easy and convenient accessory to use.

What about the garage door remote control?

The garage door remote control is an alternative to the switch. It is even the most widely used garage door drive system in use today. Its main advantage is that it is easy and particularly comfortable to use. The garage door remote control can follow us wherever we go. To operate, it does not need to be connected to the automated system. Simply program it and it can then allow remote control of the rf transmitter. Please note that the garage door remote control is very light and its transport is by no means cumbersome. The only disadvantage is that it can get lost on the way. Except that this can be avoided.
