Power on after power loss

  • Hello all,

    I have a Shelly 2 dimmer that is working great with a pair of lamps. I currently have the Shelly 2 wired inline on an extension cord which feeds to a pair of nearby lamps. The issues I am experiencing is that the outlet that the Shelly 2 is connected to is a smart outlet that turns on and off on a programmed schedule. Whenever the outlet is turned off, all power to the Shelly is cut off and when the outlet is turned back on the Shelly has power again. The problem is that when the power is restored to the Shelly, my lamps momentarily turn on and then turn off again. I am forced to go into the app and manually toggle the lamps back on. I want the Shelly and my lamps to come on and stay on as soon as the Shelly gets power, I thought this is what the "Power On Default Mode" setting was for but it doesn't seem to be working. Any suggestions how to fix this issue?

    FYI - I have other devices on this outlet that I don't want dimmed, however I want them all on/off at the same time which is why I'm using the smart outlet

  • You haven't say what you have set into "Power on default mode" but it have to be "on".

    Eventually have you "Restore last mode"

    I’ve tried all three options, On, Off and Restore Last mode. Off is the only one that works as intended. When I use On or Restore Last the lights come on momentarily then shut off.

  • This issue was resolved for me with the last firmware update that got pushed out 12/28/2020. Prior to that I was using a Home Assistant automation as a work around to trigger the dimmer on when it received power.
