It's possible to access Prota straight through the IP address with local access. Accessing the Prota via IP address will require you to:
1. Go to the Settings app on Home Screen.
2. Scroll down and you will find a section titled "Security settings".
3. Tap the "Access Protection" button and turn it off.
4. Make sure that you are connected to the same WiFi as the Prota, otherwise it can't be accessed through the IP.
5. Now, you can access your Prota through the IP address which you can find from https://prota.space or the Prota Space mobile app, under your Prota name in the Settings app.
