The do-it-yourself industry is doing well: the desire to do it all by itself gives the DIY stores stable sales. In addition, many television advisors and craft magazines encourage skillful and less accomplished DIYers to take the tool into their own hands. When it comes to building, renovating or repairing, it is saved wherever it goes – in case of need also for craftsmen.
Smart Solutions - Error display
After all, depending on the requirements and healthy self-assessment, the DIY store can also become a hobby-mine. There is plenty of fabric in electrical installation. Here the hobby craftsman can equip himself with cables, switches and sockets. Self-locking devices, current meters and entire control cabinets can be obtained there, although only specialists can install such components.

On the other hand, the "smart home", the "smart house", looks bad on the other hand. For the "networked house", where all trades are brought together centrally - where a wallboard or a smartphone app can simultaneously dim the light, regulate the heating and shut down the shutters - there is virtually nothing. If you look at the websites of the six largest market players Bauhaus, Hagebau, Hornbach, OBI, Praktiker and Toom, only the OBI search engine provides relevant results: an external wall switch, a socket insert dimmer and a week clock
Who can screw?
Reason enough for CONNECTED HOME to visit the stores of these hardware stores. In the markets themselves there were products that belong to a networked house. Most of them work by radio: sockets, flush-mounted sockets, roller shutter motors, fire detectors or intercoms.
Also interesting is
The 70-centimeter band at 433 megahertz is generally used as the frequency range. Devices that use this frequency can work together - but do not have to, as the sellers have always certified us in the markets. You have pointed out that overlapping can occur if, for example, the same channels are used in the neighborhood.
Also no topic: Encryption. You are particularly important in the amount of radio standards that surround us. It would be almost negligent if a high-modern locking cylinder were installed in the front door, but the electric door opener could be approached by radio in an unencrypted manner
In terms of bidirectionality, the low-cost solutions have the advantage. In most cases, a hand transmitter of a radio set can be activated, but the user does not register whether the can actually received the command.
At the same time, however, there are also suitable components for a cable-bound infrastructure - ie network cabling - in the construction market. Apart from a small Obi branch, there were network cables from the drum in all other markets, as well as the appropriate flush boxes. Of these, only Toom offered cat.5e cables instead of the more modern Kat.7 cables.
In all markets, a central control system was missing, or at least a standard that brought the assemblies under one roof. For example, if the installation is correct, the blinds, sockets and the heating system can be controlled via a browser or an app, and smoke or movement detectors can send a warning to the mobile phone. There are usually insula tions that are offered there. As an example, we have noted the suppliers who use the respective trades in the hardware stores visited.
Steinel seems to be the placekeeper for motion detectors. Their products were sold in all hardware stores visited. However, their field of application was limited to the switching on and off of built-in or connectable lamps. Networking? Steinel offers such products on their website. Some of them can be installed in KNX systems by bus.
The same applies to other product categories. A control center is even available for the Intertechno switching sockets offered by Bauhaus and Hornbach. The ITGW-433 LAN for 74 Euro commands via iPhone or Android app their switch sockets and could also integrate other applications such as radio gong, siren or roller shutters. However, it was not offered on the market.
Comprehensive system offerings would break the range
In the press shops of the operators, one is aware of the situation: "High-quality SmartHome products do not yet offer sufficient potential for DIY customers," says Toom and "one of course observes the market". Bauhaus points to some partially networkable product groups. However, it is also openly acknowledged that a test with home automation products has not been successful in the past and that new concepts are being worked on. Praktiker says that the "assortment is easy to break" and "is more the specialist trade."
The specialist has to
Although DIY stores offer all the components and cables that the hobby electrician needs to change or set up his electrical system, he is not allowed to bully him as a layman. The VDE standards (DIN VDE 1000-10) and the accident prevention regulations (BGV A3) clearly define who is licensed to: The modification, maintenance and erection of electrical systems may only be carried out by trained electricians.
It should also be aware of the relevant provisions, assess the work and identify potential hazards. A "electrotechnically instructed person" (EuP) may be a helper for the electrician. But even the EuP should have been trained and instructed about protective measures.
In view of the fact that few people are allowed to screw on their own electrical installations and the classic DIY market lacks product diversity in this area, the house builder ultimately has only the handle to the industry book to call a specialist. He can minimize the costs anyway: by tapping slits, pulling cables or flushing sockets, many handy hours can be saved.
