I have bought the Shelly 3EM. The electrician has installed it. I can access it in AP-mode at shellyem3-xxxxxxxxxxx. However, opening the Web-Server of the device at 192.168.33.1, it is asking me for username and password, which I do not know.
What can be done here? On the phone, the support said, I should factory reset the device 5 times. I did this by keeping the LED-button pressed for about 10 s (after 5 s it flashes faster, after another 5 secondes it flashes even faster). I stop the button press for 3 about seconds. Then I repeated another 4 times. Still, the device asks for username and password. Is this the correct factory reset procedure?
Also the electrician disconnected phase N 5 times and reconnected each time. Still, the device is aksing for a password. Please provide instructions, what can be done.
Thanks and kind regards!
