Raspberry Pi gateway can collect status data of RS-485 temperature and humidity sensors and door sensors and report data to the cloud. After receiving commands from the cloud, Raspberry Pi gateway will control the relay action accordingly. After command execution, the relay will return the current state to the cloud through the gateway. The Raspberry Pi gateway can also collect the temperature, humidity, and light intensity data received by LoRa devices and report the data to the cloud.
