Using a shelly dimmer 2 as an on/off light

  • Hi

    Is it possible to use a dimmer 2 module as an on/off switch, a light you dont want to dim, controlled with a normal on/off toggle light switch (not a momentary dimmer switch) ?

    I have tried this and i'm getting strange behaviour. I set the switch type in the settings to "edge switch" and I have connected a normal on/off toggle switch. The light turns on and off fine but in the switch's closed position the light continuously turns on and off and wont stop this cycle until I flip the switch into its off position.

    Regards

    Hi and welcome to the forum. :)

    I think, your problem based on missing and not possible calibration.

  • I have calibrated, its strange. The light remains off when the switch is toggled the one way, its if toggled the other way then the light cyles between on/off. I looked at the device using MQTT explorer, when its cycling on/off, input 0 = 1. I also noticed a long push topic, 0=1. Is this normal? is it picking up the switch being toggled as a long push?

    I have tried another light setup the same way with a dimmer 2, toggle switch in edge mode, it works fine. Maybe this one is faulty.

  • I had one do that, it was on fw 1.8.0 and also wouldn't/ couldn't connect to my wifi. Once I updated 1.8.2 it was fine, it may have been scrambled in several ways as I had to recover it with a USB flasher.

    Are you on FW 1.8.0?
