Shelly Dimmer 2 went BOOOM!

    So i've been using Shelly products for some time, both in my house and my newly bought flat. Had different kind of shelly products and there's never been an issue and the wiring is super easy and simple to go after.

    So i'm using a Neutral wire. And used this diagram https://smarthome-forum.eu/index.php?medi…rschaltung-png/ which is the same as they've got in the schematics for the product

    Yet this... weirdly thing happened. After having it installed and up & running for around 5 minutes, managed to get into my Shelly Cloud and just in the middle of firmware update it literally BLEW UP. I had a 2nd unit luckily so i swapped it out and used the exact same wiring.. Cause it's the correct one. ( I double checked my other 3 Shelly Dimmer 2 wirings aswell that's currently installed )

    But what could've caused this? Isnt there a somekind of protection inside the units or maybe this one was just faulty and something got loose in the shipping?

    Attached a picture to show how it looked like after the disaster happened

    Also one thing i remember, the unit that exploded was on Firmware 1.7 ( If that is any somehow related )

    Would you please tell us what kind of bulb is used? And did you execute a calibration? Many thanks…

    Zitat

    Would you please tell us what kind of bulb is used? And did you execute a calibration? Many thanks…

    It was 3xGU10 bulbs from IKEA that are LED with 2W each. No, i wanted to do a Firmware update before i executed calibration.

    The 2nd Shelly Dimmer has worked without any issues. Along with a firmware update aswell & a calibration with Trailing Edge ( I'm using a neutral wire )

    I've asked Shelly Support if they're interested to troubleshoot and see if it could be a faulty batch or anything. But they said no and that i should contact my re-seller. ( imho if a user comes with this kind of information i would definitly as a company taking this serious. This is a hazardous thing.. )

    The reseller should provide a new device. Obviously this issue is a kind of instant mortality…

    Similar issue here. Dimmer 2 Switch, wireless switching stopped working so I took it out of the wall to replace/troubleshoot. I then rewired just the L and N for troubleshooting (No "O") on my workbench and it went poof with a spark and some magic smoke. Looks like the L and N shorted by the blast marks which also look very different to Phillipk's Shelly Dimmer 2 burn marks. Trying to get the reseller to replace it, but they are claiming that I wired it wrong. The new Shelly Dimmer 2 replacement, in the same switch/light configuration is working well. It was powering 8x Philips(5W) or Luce Bella(6W) LED globes (I'll get the ladder out for a specific model number if that would help?). Would have been running the latest firmware as of the beginning of March. Let me know if I can provide anymore details/photos.
