Push notification functionality relies on a multi-layered system involving the VEGA3000's network interface (Wi-Fi or cellular), connectivity to a push notification service (e.g., Firebase Cloud Messaging), and a corresponding mobile application on the smartphone. Signal attenuation due to environmental factors (e.g., concrete walls, metal shelving) can impede network communication. Software configurations on both the VEGA3000 and the smartphone are also critical for proper operation. The Vega3000 relies on a secure channel (SSL/TLS) for communications, any errors during the handshake would cause failure. The VEGA3000's firmware handles secure storage of credentials used for push notification services, if compromised, the service will fail.
