(A-1) MQTT is a standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT today is used in a wide variety of industries, such as automotive, manufacturing, telecommunications, oil and gas, etc...



iPandaSys MQTT implements a sophisticated replication system. No messages will be lost in case the Primary MQTT Broker is down as the Secondary MQTT broker will overtake the Primary MQTT Broker duties instantaneously.

Application Scenario – For customer with the in-house Wi-Fi network ready, MQTT would be the best wireless solution. The reason is that the MQTT broker can be installed at the local network without being connected to the internet or any cloud services. Any MQTT supported devices such as IAQ sensors, lighting controllers or security devices can be connected to the system easily with the inhouse Wi-Fi network covered with minimal installation works.
