Shelly Dimmer 2 | Power consumtion and temprature problem

    Hi everyone!

    Yesterday I installed a new Shelly Dimmer 2 where I had a phisical dimmer, connected to a lamp with 4 halogen bipin lamps (220V 50Hz 40W each, asuming a total consumption of 160W).

    With the installation of the Shelly Dimmer 2 I decided to change the phisical dimmer to a normal on/off switch.

    A did connect the Shelly Dimmer 2 using the first diagram of the manual (Standard wiring with neutral):
    SW1 and the left L conected to the on/off switch.

    The Line wire to the middle L and the Neutral wire to the N.

    The O to the lamp, that's also connecter to the N wire.

    When I turned the Shelly Dimmer 2 on I did calibrate it using the Leading edge dimming type. With the lights turned off I verify it shows a temprature of 40°C.
    After that I turned on the ligths, and the Shelly DImmer 2 shows a power consumtion of 215W at 100% with a 70°C temprature that increase until reach 105°C after a few minutes (less than 5 minutes), resulting on the Shelly Dimmer 2 turning off the lights.

    I tried using it at 50% (showing 109°C), but the temprature increase faster than before, also resulting in lights turning off.

    Also I tried the same using the Trailing edge dimming type (after the current calibration) but the results were the same.

    I did connect and disconnect the wires to check if they were in the right place. I don't know what else to do.
    The firmware is up to date (v.1.8.5).

    Could someone help me please? I did write an email to support, I'm waiting for the answer.

    Thanks for your time!

    PS. Sorry about my poor english.

    Hi!

    I'm not sure this helps but I did the same yesterday. I have a room with 4 incandescent lights and 3 are 60 W and 1 ist 40 W. That's exactly the limit according to the manual. Since I want to exchange the bulbs by leds anyways, I discoonnected 2 bulbs and only tried with 1 60 W and 1 40 W bulb. I also calibrated leading edge and I also have 1.8.5 installed. I have 230 V, 50 Hz here. I connected without N though. So I connected like in Fig. 2.

    I didn't measure the temperature of the dimmer with a device. But I was able to touch it. Also I can have the bulbs on for multiple hours without the dimmer switching them off because of the temperature. I placed the dimmer behind a switch in the wall. There is not much space left.

    I know this doesn't fix your issue, but maybe it helps a bit indentifying the problem? Maybe you can try disconnecting 2 bulbs?
