  • Shelly 2.5 control sliding door

    I am trying to figure out if I can use 1 Shelly 2.5. Does roller blind mode also work for sliding doors? The control wires are as follows:

    24v Power +

    COM(GND)

    Open

    Close

    Stop (not going to use)

    Lock (not going to use)


    In my testing, closing the connecting with a jumper cable between COM(GND) and Open opens the door. Between COM(GND) and Close close. duh, but this is all new for me.

    With voltmeter, there is 3.6V between control cables and GND. 24V between + and -

    Can I use a 2.5 for this?

    Power 24V to Shelly N

    GND to both Shelly L's

    Open to Shelly O1

    Close to Shelly O2

    Or I could just use 2 x shelly 1, but that would be less elegant. I don't want to fry this sliding door mechanism.

  • Measuring 3 phase devices

    I would like to measure the electricity consumptions of 3 large 3-phase AC units I have. What are my options? Shelly 3em on each I know.

    Would the future Shelly 4 Pro Plus work as well? I can't find any information on using 3 phases in one Shelly 4. Would I have to use 3 Shelly 4, one for each phase?

    Also, on a 3 phase device, is it too much of a leap to assume each phase uses about the same amount of power, and just multiplying the power consumption on 1 phase by 3. In that case 1 Shelly 3em would work.
