The Humidity and Temperature Sensor and Ambient Light Sensor is the board having the sensor solder on the bottom side. You just need to connect the I2c cable to the Multi I2C Bus POT or WiFi Remote I2C and you can direct access the sensor information through the I2c bus. Since the I2c cable is included with 5V supply, the sensor board do not need any extra power supply.
As for the WiFi Remote I2C , you can make use of the PineA64 as your "sensor router". When the WiFi Remote I2c is power on, it will automatically connect to the wifi network and after that connect to the PineA64. There will be a small server program in the PineA64 that handle all the incoming connection from the WiFi Remote I2C.
As for your weather station application, your application will connect to the Server Program in the PineA64 through Tcp connection. You can either write the program and put it in the PineA64 or put it on the separate pc.
With this type of topology, Each Pine64 will be come the "router" of a sensor cluster and your weather station application can connect to multiple Pine64 to monitor multiple cluster. The sensor cluster can even located remotely since all the connection between the weather station program and small sever program in Pine64, are base on Tcp networking.
