System Architecture
Our intelligent gateway gathers real-time data from all wireless window AC controllers within its range. It converts the raw data into a user-friendly JSON format and publishes it using the MQTT protocol. This data can be transmitted to either a local or cloud MQTT broker through Ethernet, LTE (4G), or WIFI.
