Shelly Dimmer 2 with No Neutral, No AP, No Factory Reset or Flashing Red LED Lights

  • Thank you in advance for your support!


    I'm new to Shelly technologies, so apologies for the day-one questions.

    We just got several Shelly 1Ls and Shelly Dimmer 2s for our 100-year-old 110-120V home, with no neutral wires.
    We got the 1Ls working, but none of the Dimmer 2s are working as expected. When we turn the breaker on, the light bulbs (10W minimum bulbs) on the Dimmer 2 stay on all the time, and the single pole switch (not a dimmer) does not work, i.e., flipping the switch on or off does not turn the light bulbs on or off.

    Setup
    1) we wired the Dimmer 2s following the Fig 2 image on the shelly dimmer smart dimming user guide.
    2) we turn the breaker on, and the light bulbs are all on. The single pole switch does not turn the lights off or on.
    3) there is no ap, i.e., no AP mode
    4) unlike the 1Ls, the Dimmer 2s have no red light next to the reset button. When we hit the reset button, there is no flashing red light next to the reset button, and the light bulbs never turn off, i.e., the relay does not reboot.

    Perhaps the Dimmer 2s are different than the 1Ls, but on the back of the 1Ls, we see a red light next to the reset button when the 1L has power. When we reset 1Ls, the red light next to the reset button flashes, then the lights bulbs turn off when the relay reboots.

    Currently, the Dimmer 2s have no red light next to the reset button, no AP mode when the power is on, and the reset does not appear to do anything. We have tested three Dimmer 2s, and all act the same.

    We are looking forward to your comments!
