thanks!

I have one more shelly dimmer, so I will try this way. If it fails I probably install a shelly1 and forget the dimming part.

sorry to keep asking (this will be my last question)

what do you mean with "2nd Fuse in the wire for the lamp."

where and what is the 1st?

Please is there a picture to understand?

Perhaps placed in output will be more reliably.

Can you share a photo as an example please? I don't understand the "placed in output"

Because the fuse will be not fast enough to save the dimmer RELIABLY.

In most cases, the Dimmer will save the fuse…

So, the shelly can't be secured if I understand correct Reliably at least. That's very sad.

Yes, I need 2.5 Amps. But the minimum for automatic ones fuses is 6Amps. thats why I am asking. A 6Amp fuse will keep safe the shelly? Otherwise I should use the old ones with the lamps (electrician said)

A wrong setup should not kill the shelly. The problem was the broken GU10-spot, i think.

This is what I think too. But can you help a little what kind of fuse should I use before shelly in order to keep it safe if I install another problematic gu10?

This one is 10A and I think I need a smaller one. Would a 6A do keep it safe or do I need a smaller one?

Good morning

The electrician just left. The problem was in one of the gu10 spot as it seems.(short circuit in English I think). We test them one by one and saw that when we connected a particular spot there was a problem and the safety switch in my house was down.

For now we just connected the lights without the shelly dimmer. Now my question is, what kind of safety (I don't know the correct word for this) we should install before Shelly Dimmer in order not to toast the next one. My lights will be dimmable max 25 watt. A safety of 6amper will be good or do I need less?

1. I mean, if there is a problem what do I need to install before shelly in order to keep it safe?

Do you know our connection diagrams Shelly Dimmer 2?

2. I haven't seen these, but the electrician followed the basic instructions that were available in the box.

To be honest I am not familiar with the terminology like momentary switch or edge. Now that I see them I see something strange. Above there is the switch we have used. When we test it as I said it was working (one button switch where if I press it once it turns on, with the second press it turns off, and if I keep pressing, it dims the lights from max to min and vise versa). BUT in mind at least we should use the 1st diagram (for momentary switch) and as you can see in the photo below we used both sw1 and sw2. Was that a problem too?

3. One more problem I can think of is that in the beginning of the installation (with the same connection diagram as my photo we installed a double push switch. When we tested it the first switch opened the light, the second turn it off but we could not dim it. That's why we try with the one button switch and it worked.

Thanks for you help and support so far.

And if you only have 1 phase, then that cannot be true with the 400V.

anything else that could be wrong? I am almost certain that the problem is at the wiring because I can't think what else could be wrong. It is working for so many users with so many applications

Zitat von 66er

If I'm right, he measures 400V between the wire on SW and the connection L when the switch is pressed.

I sent him the message about 400V and his comment is: we have 220V and one phase (in Greece). So probably this is not the case?

Zitat von 66er

That has to be measured!

what to measured? Can you clarify please ( I don't understand) . He will come tomorrow morning and I would like to show him this conversation in order for him to understand what could probably goes wrong so he will be able to fix it.

To be honest I very bad with these, that's why I asked for electrician.

these are the photos below.

I really hope you can understand what is going on because I can't and I would like to show to the electrician what is wrong in order to fix it. I have one more shelly dimmer 2 but I am afraid that it will have problem too.

Hi all,

my electrician installed today a shelly dimmer 2 to control 6 dimmable gu10 spot (3 watt each). We used one button switch where if I press it once it turns on, with the second press it turns off, and if I keep pushing, it dims the lights. I connected the shelly in my network, updated it, and tested, for a moment. It was working ok. Turned on - off and dimming. The evening though when I turned them on, after 10 minutes the shelly made a "noise" and the lights gone.

edit: I request a calibration and I think it did the calibration. It took 4-5 minutes I think where the lights where turned on and off and (probably dimmed) but I am not sure for the dimming because we installed them in the morning)

The electrician (he has no experience from shelly dimmer) doesn't knows what is wrong. Can someone help please? What could probably went wrong?
