The default unencrypted MQTT port is 1883. MQTT (MQ Telemetry Transport) is a lightweight open messaging protocol that provides resource-constrained network clients with a simple way to distribute telemetry information in low-bandwidth environments. MQTT has been specifically designed to reduce transport overhead (and thus network traffic) and code footprint on client devices. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. You can use either the IP address or FQDN for the server address. Using 2FA authentication opens up the possibility that, if the environment runinng ring-mqtt is comporomised, an attacker can acquire the refresh token and use this to authenticate to your Ring account without knowing your username/password and completely bypassing the standard 2FA protections. To explain the working of MQTT protocol we will divide the MQTT session into 4 stages such as connection, authentication, communication, and termination. but using MQTT.fx works with these parameters: profile type: MQTT Broker Broker address: 192.168.1.2 Broker port: 8893 Client ID§: MQTT_FX_Client Enable SSL/TLS: yes Protocol TLSv1.2 CA certificate file: C:\Dati\mosquitto\ca.crt.
