Automation for a 62m2 flat - wired or wireless, which systems to choose?

Jak tanio i sensownie zbudować automatykę mieszkania podczas remontu: przewodowo czy bezprzewodowo i na czym ją oprzeć, żeby sterować oświetleniem, gniazdkami, roletami i multimediami?

Najrozsądniej zrobić prawie tradycyjną instalację z bistabilnymi przekaźnikami i doprowadzić okablowanie do rozdzielnicy, żeby oświetlenie i gniazda działały normalnie nawet po awarii sterownika, a automatykę można było później dołożyć przez przekaźniki/interfejsy [#13721918][#13723517] Jeśli chcesz czegoś bardziej rozbudowanego, to zamiast Sterbox/IUVO lepiej patrzeć na PLC (np. Fatek) albo rozwiązania typu Satel; WAGO z KNX też działa i obsługuje żaluzje, oświetlenie, TV, ogrzewanie i monitoring, ale to już wyższy budżet [#13721776][#13723573][#13763396] Do RTV/SAT warto prowadzić do każdego pokoju po 2 kable koncentryczne, z anteny/balkonu do punktu zbiorczego dać 4–5 kabli (np. pod Quad/Quatro + DVB-T/radio) i użyć na zewnątrz czarnego, żelowanego RG6; do dystrybucji internetu/TV i zasilania można dodać skrętkę [#13732750] Z HDMI nie licz na duże długości: pasywne 25 m działało tylko z niektórymi urządzeniami, a pewniejsze jest około 10 m na dobrym kablu [#13729870] Tablet przy ścianie jest wygodny dla funkcji dodatkowych, ale jako stały panel bywa mniej praktyczny niż dedykowany ekran dotykowy ze względu na baterię i czas uruchamiania [#13726849]

    @kozii thanks for the hint, I will look at your solution today. Due to the fact that I had a very busy previous week I couldn't deal with this earlier.

    It is possible to recommend a "half-measure": an almost traditional installation based on bistable relays (e.g. lighting: to the distribution board a cable from a lamp and a cable from an astable "bell" switch; in the distribution board a bistable relay; 230 Vac sockets similarly controllable;

    Suppose we have two lamps on bistable relays, one of which is switched on and we want to have both switched off when arming the alarm / leaving the house. How do you change the status of just one in this case?

    "The system" must see which bistable relay is switched on and only send a "switch" signal to it. In order for the "system to see this" it is possible to use a bistable relay with two contacts e.g. http://fif.com.pl/produkt/26/1432
    where we treat one contact as the working contact (lamp, socket) and the other as information on the state the relay is in (info via this contact to the input of the controller).

    Are you talking about the so-called hotel bistable relays? - where several relays can be controlled in groups, e.g. a floor; and at the same time each of them can be controlled individually...
    The problem of switching off can still be dealt with in another way - switch off the power for all of them for a while - they don't have a state memory so when the power is switched on again they will set themselves to OFF (and will be ready to accept a pulse to ON).

    Will this relay work with the Arduino (5V)?

    Of course! :)
    With one contact you switch on 230 Vac (lamp), and through the other you can supply the controller input (by connecting +5 Vdc)

    Thank you for your reply.
    Let's assume we have the Arduino connected to the second contact on +5 Vdc.
    Will I only be able to check the status of the relay or also control it on +5 Vdc?

    Unfortunately no! The relay must be controlled (at input 6) by a pulse from phase (L) or neutral (N). It is necessary to use an interface relay (with coil at 5 Vdc) whose contacts will "simulate" one of the wall-mounted bistable switches (paralleled).

    Could you please provide a specific model of interface relay so that I can familiarise myself with it (online instructions) and analyse the connections?

    Such to print (to include board, screw terminals and relays - you can create a multi-channel 5 Vdc/ 230 Vac output interface)
    http://www.piekarz.pl/?item=25901
    or e.g. http://www.piekarz.pl/?item=27457.
    A second solution (for stands and for TS35 rail):
    http://www.piekarz.pl/?item=36403
    The second solution is a little more expensive but FINDER can be recommended "with eyes closed". :)
