50x Shelly moduls in Haus Electric cabinet

  • Hi I am building a house and I would like to use 50 shellys for controlling lights and sockets with consumption measurement in the main home electric cabinet in technical room. Do you think it would work? that the WIFI signal will not interfere(disturb) with each other?

    Had someone used this solution?

    Thank you

    Hello Dezider Buch,

    WELCOME TO THE FORUM

    From functional side of view it should work. I don't think that the WIFI should cause any problem.

    BUT:

    When you use a lot of Shelly 2.5 in Dual-holders AND put them side by side then you can get temperature problems. For Shelly 2.5 I would recommend to let at least 1/2 unit space between the holders. Additional the ambient temperature has an influence to the resulting inside temperature of the Shellys.

    Grüße Bernd

  • hello, thank you Guzzi-Charlie for advice about temperature problems :thumbup: I have big cabinet so any problems with space between modules. Maybe I can use for safety external temperature sensor for shely 1pm and I become push up warning notification that temperature is above 40°C in cabinet. Or maybe use some of billig tuya WIFI thermostat for this message.

  • I agree to have at least 1/2 unit spacing. Btw you will need additional terminals for power distribution. It is very easy to get messed up with all the necessary wires.

    Don‘t forget not to mix up phases for control and power at a single device, otherwise you‘ll damage it.

    Each single Shelly will tell you the internal temperature, therefore additional sensors are not absolutely necessary, maybe helpful.

    You will need beside all the Shellys a central controller. Without your possibilities (i.e scenes) are limited. Which controller? There are so many possibilities. Software based or hardware (PLC), it‘s your choice. You could use instead (or beside) the Shelly APP and/or Shellys cloud services, reliability is another question. I would never trust the cloud.

    Mit der Elektrik ist das doch ganz einfach. Alles, was man sich merken muss: Rot ist Schwarz und Plus ist Minus, dann klappt‘s immer:!: Und beim Programmieren hat man auch nur Nullen und Einsen, also wie kompliziert kann das schon sein:?:
