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



  • With 8 Modules i've no problem. :thumbup:

  • 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.

  • Hello, for my instalation I dont need home server, shelly works also good without internet with URL actions turn on off brightness....

    Has shelly function that come notification when is power lost on L N? Tuya products have this feature that device offline notification, but in shelly I didnt find this function. Is good to have this option, that than I see that is problem with my power network.

    I will use this connection fur sockets:

    Good luck with 50+ Shellies... Don’t forget, that more than 2 actions per shelly are not recommended. A single Shelly isn’t a controller.

    Where should the notification come from, when Shelly is dead? With the last breath just before she closes her eyes for ever? What shall be the content, „R.I.P.“?

  • Right, but before it was mentioned, that „shelly works also good without internet...“. This suggests the absence of any external cloud service. And furthermore „...I don’t need home server...“ will kill any chance.

    Depending on your skills earlier or later you‘ll use cloud services (i.e. How you would like to accumulate long term power consumption), home server or PLC.
