  • Smart Home wireless technology - a guide

    The hallmark of smart home systems being developed today is to expand their capabilities while simplifying how they are installed and configured. At the moment, the average smartphone user, able to set up Wi-Fi access, will be able to automate their home without the costly involvement of specialists.

    When we become the owner of a secondary market flat or house, we are additionally burdened with the baggage of very costly renovations and building alterations to bring the property up to a satisfactory level of quality. What if we want to become the owner of an automated home?
    Smart home technology enthusiasts opting for the installation of a smart home system that does not require the wiring to be laid out for it can save hundreds of zlotys with this choice.

    Smart Home how to get started? `

    The smart home systems market is growing rapidly. There are now at least a few starter kits available in the shops to start the adventure of automating the home and improving the security of the household. The kits vary in their wealth of equipment and price spectrum. A set allowing the control of temperature, humidity, containing motion detectors, a contraption can be purchased for a few hundred zlotys. There is no upper limit, as the Fibaro systems start at amounts well over PLN 1,500. It is worth choosing a system which we will be able to install on our own, thus not generating additional costs. In many cases, the installation of the systems is very simple and does not trouble the average user. Let us look at how to start such an installation.

    Why ZigBee technology?

    Alarm and smart home systems must be based on a reliable communication protocol for the individual devices that make up the system. The system should work properly even if one of its components fails. For this to happen, the network formed by the nodes should be of type mesh . A broken node in such a system is intelligently bypassed and an alternative path is found, so that communication and management of devices is still possible. The ZigBee communication protocol provides just this type of device interconnection.
    Another characteristic that underpins this system is its energy efficiency. Thanks to minimal energy requirements, the end devices, specific detectors, are able to operate without changing batteries for many years, ensuring the safety of the occupants and increasing their comfort of life.


    Heart of the Smart Home system - hub/central unit

    Smart Home in wireless technology - a guide


    The construction of each smart home system begins with a discussion of its heart, the hub often referred to as the gateway device this often supports several communication standards, which allow the system to be controlled on the one hand and the user to control it remotely on the other. The user controls the hub via an app available for smartphones, connecting to it via the internet and Wi-Fi. In addition, the hub can act as a siren and warn of detected threats with a light signal.
    Configuration, management, arming the system, querying detectors for their status, all these functions are performed by this device.

    Secure window openings, doors, gates

    Smart Home in wireless technology - a guide


    A signal that a window or door has been opened while we are away from home indicates an attempted burglary. In order to detect this type of unauthorised action, windows and doors should be secured with a multifunctional sensor. The reed switch is a small component consisting of two parts, which are fixed in parallel on the moving window/door sash and its frame. The multifunctional smart home sensor is also suitable for securing office cupboard doors storing important company documents, garage doors, ceiling flaps leading to the attic, etc.

    Motion detectors

    Motion sensors detect the presence of people in guarded premises. They allow the user to obtain information about an approaching attacker and can also determine the occupancy of rooms in the house. As the installation of the sensor is simply a matter of sticking it to a selected spot on the wall, the user only needs to be mindful of its detection areas in order to make optimal use of its capabilities.

    Flood detector - bathroom guard

    The flooding detector is distinctive due to its design. It consists of a detector and a probe which, thanks to its small size, can be placed even in inaccessible areas at risk of flooding. Here again, the advantage of wireless communication of the system components is worth emphasising. Installation of the detector takes seconds and requires no chiselling, no destruction of tiles, wall structure or additional wiring. It is a good idea to protect all rooms with water and sewage system valves with a flood detector. This is most often the floor area around the shower, bath, washbasin, washing machine, wc, but also the dishwasher and sink. In detached houses, we should consider protecting basements. Particularly in hard-to-reach or infrequently visited areas, it is worth placing a flood detector to prevent the damage that a water leak can cause.

    Autonomous sensors

    Alarm systems can include standalone sensors that will also serve their purpose without being connected to a hub/central unit. This type of device can include sensors for detecting chad and smoke detectors. The standalone sensor in such cases is equipped with systems to warn the user of the danger, such as a siren and an LED beacon. The downside of using these system components autonomously is the lack of control and monitoring, available remotely from the hub management application.

    Remote management of a smart home system

    The strength and usefulness of the Smart Home is determined by its ability to be managed remotely using mobile devices. The system administrator, thanks to the appropriate application, can monitor the home environment, as well as remotely issue commands to household appliances. How easy it is to use the app to configure the chimney detector and update it can be seen in the example instructional video of Ferguson's SmartHome system.






    Intelligent socket - remote control of electrical appliances

    With smart sockets, the user gains the ability to remotely control connected devices. It becomes possible to schedule the activities of these devices and create scenes involving them. An additional plus is often the ability to monitor the electricity consumed by a device.





    IP cameras - remote home monitoring

    Smart Home system administrators concerned about application alert signals have the ability to view and record video from their home thanks to IP cameras. Current cameras provide Full HD video recording, have a built-in microphone and speaker, and LEDs to illuminate the room in night-time conditions. Thanks to the motors installed in the camera, the user can rotate the camera from their smartphone or tablet, monitoring the room in which it has been placed.

    Infrared transmitter - one to rule them all

    Smart home systems can include IR transmitters. These are devices that can be taught to operate and control all the white goods/appliances that normally need to be managed by an IR remote control. Using a single transmitter, we can remotely control the TV set placed in the room, the DVB-T/S/C receiver, home cinema, air conditioner, roller blinds, LED lighting and so on. Timers and the ability to create scenes are very useful functions of the IR transmitter.

    Smart Home - it's the present

    The smart home is slowly becoming ubiquitous. ZigBee technology, used to manage household appliances/RTVs, is now being used by some of the world's biggest companies. The LG smart fridge, the Indesit’u smart washing machine are just a few examples of the use of this wireless protocol. Developments in the technology itself are making it more accessible and cheaper every year. Home management from a smartphone by a Kowalski is not a distant future, but a turn of events for which we are already mentally ready. SmartHome Security Kits show how easy it is to do it yourself.

    Intelligence (from Latin intelligentia - ability to comprehend, reason) – the ability to perceive, analyse and adapt to changes in the environment. The ability to understand, learn and apply one's knowledge and skills to new situations. A feature of the mind that determines the efficiency of cognitive activities such as thinking, reacting, problem solving.

    This system (and probably all others on the market) is at best an automation system. It lacks intelligence.

    Because such has not yet been created. So there is nothing to cling to.
    When touchscreen phones are called Smart Phones nobody screams and when automation is called smart there is smoke.

    For me, wireless communication is always a topic for a longer discussion.
    On the one hand, it is now possible to build miniature devices, powered by batteries and communicating wirelessly with the rest of the system.
    On the other hand, when you have a wireless alarm detector, you need to be sure that the detector is in range (e.g. not interfered with) and has working batteries, and that the signal you are receiving comes from your motion detector, glass-break detector or CO detector. Today, the task is facilitated by cryptography (as well as hardware cryptographic solutions for IoT e.g. ATSHA204A and many others).

    I'm curious what your preferences are for short-range wireless technology, the aforementioned ZigBee solution is quite well known, more recently BLE has become increasingly popular, and you can also find solutions based on proprietary (often quite simple) modulations and protocols operating in the ISM bands.
    It would be hard for me to point out the best technology, each has its own advantages and disadvantages and may work well in certain conditions, I am curious what you think.

    My opinion is that moving away from Wi-Fi in the simplest and energy efficient devices to Bluetooth low energy/ZigBee/XBee/6LoWPAN is a good idea, for longer distances LoRa can be used.

    More and more devices are becoming 'smart' and in some cases this is a very good idea, e.g. remote access to the heating system , in the case of CO there are overlays on the heads allowing the control of the radiators.

    It would be nice if the 'smart' home was a gateway to the internet for functioning devices and a platform for IoT devices to communicate with each other. The ability to add more devices is an interesting idea to gradually develop the system as needed.

    A lot of work remains with standardising communication and ensuring security, we will see what the near future brings.

    Don't you think that half of these are gadgets that are not at all necessary and make life very complicated? I've stuffed a lot of electronics into my house and now I'm servicing it, and I can see that most of it makes no sense at all to involve a smartphone. If the electronics are to work on their own and be completely invisible and unnoticeable, tangles of cables or hanging boxes create an overall mess. Even the wireless ones require access to power and usually no one can predict at the design stage what will be fixed where and we already have cables and plugs...:)

    In my opinion, sensors and other 'smart' gadgets powered and communicating via UTP are the best (when building a new house). No more problems with range, power supply or interference. And twisted-pair cable itself is so cheap that laying a few hundred metres (if not over 1km) when building a house is a negligible cost.

    @submariner I was waiting to hear from a practitioner who uses a similar system. It's certain that a lot of gadgets are redundant, however everyone may have different ideas and needs. For example, for me, remote information received e.g. on a smartphone app that there has been flooding or a gas leak, running a camera view would be good, as would the ability to remotely change the heating settings or turn off the water or gas supply.
    Why a smartphone: because we have one anyway, it has a convenient display internet connectivity (or local bluetoth/WiFi).
    Of course, it would be good for the 'smart' home to have some autonomous emergency/control behaviour where neither smartphone nor internet is needed.

    @DamianG for me as a technical person, a wired bus providing communication and perhaps power is an excellent solution. However, knowing the market, one should be open to wireless solutions.
    Why?
    Because the customer expects to take the sensor box out of the box and stick it with double-sided tape in the desired location. He or she will change the batteries once every few years, while the gateway for the devices will be placed somewhere invisible, supplied with 230V and connected to the home LAN. It should be convenient and easy.

    Unnecessary gadgets are e.g. control of lighting via the net: when I'm lying in bed, I don't really want to look for a smartphone, for example, which is usually not at hand, and it takes time just to launch the application. The hoover has its own software, so I didn't even use the remote control, besides, its intelligence also leaves a lot to be desired. It can clean itself if you help it from time to time, because it gets stuck under a stool and screams helplessly.
    Controlling the heating is not very convenient either, even though it is a heat pump, because the inertia of the heating is so high that you have to think about it much earlier; I replaced it with a timer so as not to bother myself and not to think about what I forgot.... The control of lighting and everything that has infrared, e.g. hoover, is implemented on the module http://www.ibroadlink.com/rm/ and not expensive zigbee ...
    Only remote monitoring works, admittedly it takes a long time to log in and not always :)
    but there is not much of an option, the smartphone itself is not the last one because it is a Note4 but the problem is too slow mobile internet.
    Sometimes I'll turn on the lighting remotely then something messes up and I can't turn it off for a couple of hours (the system resets itself every couple of hours).
    I will stand by what I wrote earlier , it has to work on its own so it doesn't make you think what else.... :)
    Alarms yes at my place is another system that sends text messages and calls back, but still there is not much you can do being a few hundred kilometers from home, of course I can always then see on the cameras or turn on the wiretapping, but it still has to involve a neighbour to help, hm once there was even such a necessity ...
    Maybe some android should roost around the house? The Alexa system handles conversation quite well and I would see it in such an android as much as possible.

    Everyone will expect different functions, so it is good that there are different products available. E.g. for me it would be important to monitor (e.g. flooding/smoke) rooms such as the basement attic, and to remotely control devices e.g. in the boiler room. It is also important to me that the devices come in wired and wireless versions, then you can choose the optimal solution.

    BroadLink RM Pro is a very interesting device, it is a pity that there is no ethernet version preferably PoE. What is the price of the device on the Polish market?

    Maybe it's old-fashioned, but I must admit that I am surprised by the sheepish enthusiasm for the possibilities of modern home electronics. It's as if getting up from a chair and switching a light was a task beyond one's strength and that one had to use a remote control or even a smartphone to do it. For a long time now, I have been of the opinion that modern man has made his life easier with various inventions in order to go to the gym after work (not for free, you have to pay there!) and waste time. However, there is still no time, and for several hundred years workers have been demanding an eight-hour working day, but no progress has been made on this issue to date.
    But back to the substance, the Smart Home system. Enthusiastic about the new possibilities for growing fat in the hips (women) or belly (men), we pay little attention to the dangers and hazards that come with equipping the home with modern gadgets. I am not going to transcribe here an interesting article I found on the internet, I will only quote an extract:
    Quote:
    The first and simplest form of threats, physical threats. Smart Home components are vulnerable to physical damage, which can lead to a disruption in communication between the various components. Some of the equipment in such a home, such as smartphones or tablets, may be brought outside, where they will be even more vulnerable. Furthermore, most manufacturers of such equipment assume that they will only be used by members of the household. However, it turns out that if a third party gains access, they can update software, add new hardware components or change settings, or even introduce encryption.

    The danger can already arise in the design or construction phase of Smart Home tools. Inappropriate or poor design can be a source of danger and negatively affect individual Smart Home components, but also the entire system. At the level of specific solutions, insufficient security solutions may be implemented. For example, poorly configured SSL protocols may mean that information will be transmitted in an unencrypted manner.

    Currently, there is no standardisation of the creation of smart devices within the Smart Home. Therefore, there are many design paths for such solutions. Each has different security and privacy standards. Some manufacturers may not have experience in creating secure solutions, and some will only slightly modify off-the-shelf solutions without improving the security mechanism. Programmes such as Security by Design or Privacy by Design may be completely alien to them and not applied at the device design stage.
    Another problem is the often used, simple, factory-made passwords that cannot be changed. In the case of smart light bulbs, the password may be their year of manufacture, which makes the job of hackers much easier. Introducing the ability to change passwords is not expensive, but as the manufacturers point out, there is no customer interest in this solution, which is due to the rather low level of awareness of the threat among buyers.

    There are more dangers, you can read about them here:

    Fundamental considerations if you are securing your home like this because you want to save money on an alarm system:
    - immunity to interference, operation when there is no communication with an element, the time it takes to query elements, etc.
    - the approach of the insurer. None of the elements of such a system meet the standards, so it cannot be treated as an alarm system and reported to the policy in order to get an insurance discount. In the event of an incident with such a 'system', the insurer can safely write us off. But no salesman will tell you that.

    I myself am experimenting with my own home and am currently installing various "extras" on a makeshift basis. In my opinion, such automation is pointless. Ultimately, it involves us more than it relieves us. A good way is to have independent "blocks", without control panels, controllers etc. If it breaks down, it's one thing and not everything. But that's a discussion for another topic.

    Despite the fact that the colleague wrote about the real dangers and I "don't have a smartphone" and "don't have a facebook account" or other strange to me inventions of modern society, I still think that the colleague is exaggerating.

    I'm not fighting against progress, I'm just pointing out that sometimes we behave like kids who heard about Pokemon. Mankind survived for a million years without Pokémon until suddenly massive advertising convinced preschoolers that it was impossible to live without them.
    We, who supposedly already have a mind of our own, are often dumber than kindergarten children here and let ourselves be led around by the nose even more. After all, this is not about any profit. We don't get it at all, unlike many inventions that make work easier or extend life and health. It's just a gadget, pressed by advertising and persuaded like ladies to a fashionable blouse or trousers. "You must have it!" - this is the motto of happiness to which we succumb. "You must have!" Never mind that it's as unnecessary as smoking cigarettes, but "You'll be modern!".
    Yes... that's it, I won't ramble any more.
