CurrentCost bridge custom firmware

CurrentCost

This sketch is for the CurrentCost Bridge device that causes readings to be published over HTTP using JSON.

Sending interval is set to 5 minutes and the value is an average of all packets arrived to the bridge.

You will need a programmer to upload this sketch to your device. I am using a USBtinyISPv2 but you can use every programmer that is listed in the arduino IDE.

Customize

You will need to specify the SERVER_HOST_NAME and uuid.

Installation

This must be compiled with the board set to: Arduino Pro or Pro Mini (3.3V, 8MHz) w/ ATmega328

Plug the ISP into the 6-pin header on the bridge board. If you have the ISP set to power the board make sure you haven't got the bridge's own power supply plugged in. From the Arduino IDE, burn the bootloader. To do this, first ensure

Tools->Board->Arduino Pro or Pro Mini (3.3V, 8 MHz) w/ ATmega328

is selected. Make sure you select the correct type of programmer Tools->Programmer.

After that just press CTRL+SHIFT+U(or Sketch->Upload Using Programmer) to upload using the programmer.

Consuming the data

The bridge will make a PUT request to the specified url with a payload like the following.

[ {"id": "0", "value":"420"}, {"id": "1", "value":"80"}, {"id": "10", "value":"25.4"} ]
