Multiple wifi remotes

You can connect all the Wifi remote IO through a wifi router or ap to connect to Pine A64 board. Pine A64 can run a Tcp server to accept connection from Wifi remote IO unit. on the Wifi remote IO unit you can run a Tcp client connect to Pine A64 and forward the temperature and light sensor info. The Wifi remote IO need to manage it's own I2c bus. Connecting 5 unit of wifi remote IO to one Pine A64 should not be any problem.

On the Wifi remote IO unit, only have one 5pin I2c port. Since temperature sensor don't have address selection, you can only have one unit per I2c bus for the same device. Light sensor can share the the I2c bus with temperatures sensor because it has different Device ID.

as for the Wifi remote IO connection distance with on board antenna, it is all depending with the surrounding environment but normal is about 5 to 10m. for longer distance, you should install an external antenna.

For more information on the Wifi remote IO unit, you can refer to ESP8266 module datasheet at
