If startup problems occur, there are already some threads and lexicon entries that can help. Just have a look at the appropriate subforum or use the search.[Blockierte Grafik: https://smarthome-forum.eu/attachment/1350-forensuche-png/]

By the way, it is not so rare that the router password is accidentally entered in the Shelly instead of the WLAN key. Of course that doesn't work! You should also not rely on the WLAN password that is often printed on the outside, because this could and should be changed during operation. So if you have problems -> check the password in the router / AP.

The Shelly don't like special characters in the SSID and in the network key.

And if you integrate via smartphone, you should switch off "mobile data" so that only WLAN is active.

By the way: The Shelly don't like special characters in the SSID and in the network key. A hidden SSID is also a stumbling block!

And if you integrate via smartphone, you should switch off "mobile data" so that only WLAN is active. Otherwise, the smartphones switch to the mobile data world during the coupling process and of course no longer find the Shelly. Problems are "inevitable".

How to reach your Shelly in Access Point Mode (AP) is described here

If you have problems with the Shelly Cloud APP, this lexicon entry will help.

Are you having trouble getting your Shellys into your own network (Client-Mode (CM))? This lexicon entry could help.

Explicitly? No.

How exactly can I do that, keeping in mind that I can't save any setting?

I have a feeling that I don't understand what is expected of me to do.

I did try it.

Connect the laptop to the iPhone hotspot.

Then connect the second iPhone to the laptop via cable and share the internet from the laptop.

I checked that with mobile data turned off and no wifi second iPhone has internet.

Open the Shelly app.

Find Dimmer 2.

Try to update Firmware.
And get the same message that there is no internet connection.

And was not able to save anything as well.

Let me try.

What I find a bit confusing is that connecting to a second phone WLAN (hot spot) will use a WiFi connection.

And I will lose it as soon as I will connect via WiFi to the Shelly Dimmer. You can't connect to 2 WiFi points at the same time, right?

connect the shelly to the WLAN-AP of your smartphone.

How can I do it, if I can't save settings with wifi name and password on Shelly DImmer?

Personal hotspot is working on the phone, yes.

The firmware can potentially be updated.

The exact version is on the screenshot.

Right now, I only have the Internet on my phone.

If I try to update the firmware, it says that there is no Internet connection.

I would assume that's because I am connected to Shelly DImmer WiFi point, and it does not have an internet connection.

But I don't know how to allow the use of mobile internet.

Hi.

I am trying to set up Shelly Dimmer 2.

I open the Shelly app and click add device.

It did find a dimmer and proposed to connect to its wifi point.

I did connect. Then device is shown in pending state.

I open the internet settings and enter the local 2Ghz network login and password.

But I can't save them. Same with other settings.

Afterwards, I disconnect from the wifi point of the shelly dimmer and it disappears and in the app saying it's offline. Which make sense, because dimmer can't connect to wifi without a password.

What has gone wrong?

Yes. Shelly 1 (or plus 1) will need a relay too!

Thanks, I got it.

Pin L of the Dimmer2 is IMHO connected to live wire of mains supply.

Disagree! If you need a boat to cross a river and have a car available, you’ll perish…

Unfortunately, pin SW of Shelly Dimmer2 (at which one line of the Prado is connected) delivers not enough energy. This is why the circuit will not work.

I feel confused a bit: if the power input of the Prado push button is connected to L directly, then it should get all power it needs?

Or it's push button signal output is not good enough to turn on the SW pin of Shelly? But why then fan starts? And then stops?

The video is too big to attach, so I uploaded it to twitter:

Well, it seems that Shelly 1 or Shelly 1 plus are cheaper.

Or do they need a coil as well?

Well, I am not trying to cross a river in a car. I am trying to use Dimmer as a Switch. Is there any particular reason why it wouldn't work?

Zitat

A Shelly 1 or plus 1 would be the best solution for this issue! Not a Shelly Dimmer2…

Probably, but I do have Shelly DImmer 2 and don't have Shelly 1 or plus 1.

So I would prefer to solve this without buying additional equipment if it would be possible.

Hmm... prado is connected to L of dimmer, but I can also connect it directly to the line.

The signal output is connected to the SW of the dimmer. I have a feeling that either I connected it incorrectly,

either I don't understand why SW should output any power.

Am I correct and SW is for signal input, and O is for signal output?

So the load should be between O and N?

And O providing power to load?

> Would recommend to use a relay/contactor with 230V AC coil and a NO contact. The coil is connected at Prado pin and neutral; the contact between live and pin SW of Shelly Dimmer2.

Sound interesting. Can you please give me an example of this coil?

I found https://hpcontrol.eu/cewka-16mm-z-e…230v-ac-dc.html

But I am not sure if it's something related and how it can help. It seems to be a magnetic coil for the solenoid valve?

Regards. Anton.

Also, about fan:

Looks like it's ok to turn it on and of, but not change the speed. And that's what I need. Turn it on and off.

Thanks, I will keep this in mind.
But what about the push button problem?
I have it wherever I connect a fan or lightbulb.

HI.

I am trying to connect the exhaust fan to Prado push button via Shelly Dimmer 2.

- push button: https://prado.eu/products/rond-2-0-push-buttons/

It works from the Shelly app interface, but if I click the button, it switches the fan on and immediately off.

I would assume that pressing the button produces 2 signals.

What can I do from the shelly side to fix the situation?

Regards. Anton.
