    It is very helpful for me because i can use it with battery, so don't need electricity. I can switch on/off the stairs lamp.

    i moduli funzionano molto bene e sono molto utili e si possono usare "dappertutto " naturalmente dove serve e prendono poco spazio . Attenzione nno usate le uscite del modulo per pilotare direttamente led o quantaltro , usate gli ULN2002 o altri a seconda dell'uso .

    Works as expected. Antenna not included. Use a copper spring to increase the range. Just a piece of wire works ok in a room.
