    Dobrý den, tento modul komunikuje pomocí standartního sériového rozhraní SPI. Je tedy nutné k jeho ovládání a provozu nějaký mikrokontroler. Samotné tlačítko a na přijímači relé fungovat nebude. K Vašemu účelu by se spíše hodil tento produkt: https://www.laskakit.cz/sada-vysilac-prijimac-433mhz/

    Dobrý den, je možné tento modul použít pro kominikaci s protokolem RFIO (INELS RF Control). Děkuji

    Dobrý den, tento modul je pouze rádiová část komunikující s nadřazeným mikrokontrolerem po sběrnici SPI. Jaký přesný protokol tam budete používat by mělo být jedno. Bohužel Vám přesněji poradit nemůžeme, protože protokol RFIO (INELS RF Control) neznáme.
