I think you can get the desired behaviour if you configure night mode for the whole day and set its brigthness to 100%.

The idea of night mode actually is to specify a time interval of the day in which, when you pres the button, the brightness goes to the fixed specified brightness, no matter what the brightness was last time it was on. So when you want to go to the bathroom at night you can safely get 10% brightness when turning on the light without fear of getting a 100% shock. So setting the time intervall to the whole day and setting it to 100% probably will do the trick.

I wished for this behaviour as well before I made another discovery: If you leave eveerything the way it is, you can always turn the light to 100% immediately by double clicking the button. I have not found this in an documentation. I just discovered this at some point by accident. But I really like this. So now I can switch the light on to the last brightness by normally pressing the button and if I want it full brigth I just do a quick double press instead.

Hi !

I have 8 shelly dimmers running at my home with 1.9.6. Two of them now calim there is a firmware v1.10.0. I can't select such a version in the firmware archive. It also has an odd ending:

Current version: 20210226-115010/v1.9.6-dimmer2@1873d25e

New version: 20210318-141630/v1.10.0-geba262d

Usually, they all ended by -dimmer2. Now it ends with geba262d.

Is this legit? Should I try updating?

FYI: The ticket got a response with first of all I should make a video and send the settings of the device. I sent both.

Then I got the answer that it's wrong to turn off the dimmer with a short button press and you have to use a long button press in order to dim to 0 % to turn it off. That's kind of odd because that basically means there is a state in which a user could do a short press of a button and that's "wrong". That's super counterintuitive. Furthermore, I set my minimum brightness to 20 %, so I can't even dim to 0 % with a long button press.

I still think it's a software bug but the service person who answered my ticket didn't really understand the issue and just answered something.

Yes short press is toggle between on and off, but that happens with the transition time defined in the settings always, except when the dimmer is in off, then you turn it on by a long press (dimming) and afterwards just do a short press. Then there is no smooth transition to off. Instead it immediately turns off.

If you turn it on with a short button press, there is a smooth transition to the last brightness. If you then turn it off with a short button press, there is smooth transition to off.

I think it's wired that the smoothness happening when turing the light off depends on wether you turned it on with a short or a long button press before.

I just wanted to mention that I notice this as well. I have connected my shelly dimmer 2 without N though. But the reation also feals lagged.

That'ld explain the low working temperature mentioned in the manual..

So what are reasonable temperatures of the dimmer? Is it just "everything below 105° C is ok" ?

Hi !

I was browsing through the forums and found multiple reports of people having high temperatures on their shelly dimmer 2s. So I checked mine (which you can do by accessing this address http://%7bip of your dimmer}/status ; then find "tmp" and behind that there is temperature values in celsius and fahrenheit) and I have 46* C with lights off and 57* C with lights on.

Now this seems quite low compared to the reports here in the forum about reaching 105* C and such. It seem pretty high though compared to the Specifications mentioned in the 2-pages manual. There it states: Working temperature: from 0° C to 35° C.

Does anyone reach such low values?

What are your temperatures?

Hi !

I got a shelly dimmer 2 days ago and installed it. It works well so far. However, there is one little thing that seems like a software bug to me:

I have my shelly dimmer 2 connected like in fig 2, "no neutral wiring". I'm using 1.8.5, I upgraded immediately when I installed the dimmer so I don't know if the issue also happenes with older firmwares. I think 1.7.1 or so was installed out of the box. I don't remember exactly anymore.

I have 50 Hz, 230 V. There a 100 W old bulbs connected and I calibrated with leading edge.

Now the issue:

When I hit the switch for a short time, it fades the light on to the brigthness it was on the last time I turend it off. If I hit it again for a short time it fades back to off. This is fine.

However, if the switch is in off and I hit the switch longed, it starts dimming the light towards bright. When I release the button it stops at the current brightness. If now, I hit the buttne again for ashort time to turn the light off, it switches the light off immediately. It skips the fading. I can reproduces this 100 % of the time.

Is this the right place to report this? If not, where should I put this instead?

In case this behaviour is intended for some reason, I'ld like to hear the reasoning behind it.

Thank you very much

Oh thanks, I plan to buy IKEA Ledare as well for use with the Shelly Dimmer 2.

Hi!

I'm not an expert on this and I haven't had that issue yet but I'ld try adding LED lights with more wattage or the bypass for a try. The manual says 10 W should be enough, but 15.2 W is not that far away. I switched to shelly dimmer parallel to upgrading with old bulbs to LEDs and specially choose the high power leds so I don't come close to the 10 W.

Is there a way to see the temperature from the dimmer without taking it out of the wall and measuring it by hand? I can't find the temperature displayed in the webui.

Also, shouldn't theoretically trailing edge always be the one you should use for leds? I thought they never work correctly with leading edge?

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?
