I have had exactly the same problem and am awaiting a response from Shelly support. The bulbs are stuck on and flickering, the Dimmer 2 does not respond via wall switch or visible in the app anymore.

I also have the same problem with a Dimmer 2 installed in a 'no neutral' configuration with a Bypass. The WebGUI and App report it as off but the bulb is probably about 60% and flickering, it just won't go off. If I power cycle the Dimmer 2, it instantly comes back on flickering.
I've reset, updated, power cycled, changed to neutral configuration, still the same outcome, flickering bulb and the bulb won't turn off!

Hi,
I also get Error 1 while dimming 5pcs 5Watt dimmable Led
100% seems to work but if dimming afer a few seconds light turn off and error 1
please fix this
I had this issue and could see the unit was going over temperature and generating Error 1. I raised a ticket but found that calibrating as Trailing Edge fixed it. Bit scary seeing the temperature Sky rocket to 95 Deg C in seconds when dimming!

I received the following from Shelly Tech Support:
ZitatOur cannot trigger fire, all parts are certified to run on 120C continuous work, protection is triggered on 95C.
My ticket is still open...

UPDATE!
On both my Shelly Dimmer 2s running firmware 1.8.4, with either trailing or leading edge calibration it would cause the temperature to hit 100 Degs C and cut out.
I downgraded the firmware to 1.8.2 and trialled with leading edge and the temperature still hit 100 Degs C and cut out. I changed it to trailing edge and now it all works, stable at around 65 Degs C with any % load.

I’m experiencing exactly the same issue, with 8 x 7W LED GU10s on firmware 1.8.4. Changing the calibration makes no difference.
My lights go off as soon as they get to 100% and it’s often too quick to see the temperature increase and go out on thermal cutout; we’re talking 3-5 seconds!
I can replicate the issue on another Dimmer 2 by setting the levels to 50%.
