Unable to find network in list when adding new device

Did you go trhu first steps when a Shelly is powered up for the first time and it builds its own WIFI to which you have to connect first, in order to integrate it into your WIFI?

After connecting to Shellies WIFI (by Smartphone with deactivated mobile internet connection) you have to open Shellies configuration webpage by entering the IP address 192.168.33.1 in your webbrowser.

Once you went thru this steps and entered the credidentials of your WIFI and saved the settings you can open the App and after a few seconds the Shelly should turn up as discovered device for further configuration.

Best is to add one by one and before the are built into your walls and are hardly accessible. A lot of users use an open end cable with plug on one end (be careful when doing that and always diconnect the plug first before you touch anything), such they can be configured and once everything works fine they can be transfered to their final location.
