Thanks Michael,
sorry, I didn´t look at the screen shot with enough focus. So I got in the wrong area of the app. If I actually press the right buttons, everything works :).
I´m either looking in the wrong area or the app changed, dunno, but I don´t get the "add by ip" option.
1. Open Shelly App
2. Press blue button lower right corner ("+")
3. Choose an action ("Add a new device // Scan your netwrok for devices")
4. Press "Add a new device"
5. Inclusion type ("Bluetooth // WiFi (AP Scan) // Scan Barcode")
6a. Select Bluetooth (there will be nothing, I´m in a different room): Nothing found, no option to add by IP
6b Select WiFi (I´m in the same network as the Shellys): Nothing found, no option to add by IP
Is there another path to get to the page you uploaded?
