The Vetrax Sensor can be connected to any encrypted 2.4 GHz Wi-Fi network. Additional login credentials such as accepting terms of use, providing a room number at a hotel, or any other non-traditional login practices, will prevent your sensor from connecting. While the Vetrax Sensor supports connecting to an open network by being manually configured to do so from within the Vetrax App, we do not recommend using an unencrypted network connection.
