# | # The EVSE does not use a watchdog and continuous communication is not needed. As it is possible to change the EVSE settings by using the TeltoCharge mobile application, it is recommended for the primary device to read, compare, and change settings as needed based on user preferences and real-time requirements, ensuring a seamless and secure charging experience for electric vehicle owners. Continuous monitoring and adjustment of EVSE settings enable the primary device to stay synchronized with user inputs, maintain optimal charging conditions, and promptly respond to any changes initiated through the TeltoCharge mobile application, thereby enhancing overall efficiency and user satisfaction. | ||
