Open the App. You will be asked to connect to a Host. Tap "DEMO HOST ADRESS" and change the IP to the IP of your Server, do not change the port number (everything after the IP. This should look like `192.168.1.15:59661`).
You will find an overview of the installed machines including the option "SCAN QR-CODE".
Next step is setting up you machines so they can be switched on an off.
**Step 4 Prepare your Shellies**
as long as your Shelly has not been given the credentials for a WLAN, it will create an access point (AP) for configuration when connected to the supply voltage. This AP will appear in your list of WLAN.
Connect to this Shelly-AP and connect to `192.168.33.1` in your browser. A configuration page should appear.
If your Shelly is already connected to your WLAN, you must find the assigned IP-Adress (e.g. by looking into your router). Enter this IP Adress in your browser and you will get the configuration page.
Open the file "bffh.dhall" in the GUI Editor (just by double-clicking it)
Change `Shelly_123` to your Shelly name, e.g. `shelly1-123456789ABC` (**case sensitive!, dash sensitive!**) in "Link up machines to actors" and in "actors".
Change the third IP-adress under "listens" to the IP-adress of your computer.
**- save**
21. start Diflouroburane
change to the directory in the console where you checked for the ip-address
