RPICT8

Link to shop

This page is for board specific information. More information can be found on the generic page for RPICT series.

  • 8 AC current sensors.
  • Compute real power.
  • Fit on Raspberrypi 4 holes mounting pattern.
  • AtMega328 Mcu (Arduino UNO)
  • MCP3208 12bit ADC
  • Stackable (up to 5 boards together)

Compatibility

Version Compatible?
Raspberrypi 1 A No
Raspberrypi 1 B+ Yes
Raspberrypi 2 B Yes
Raspberrypi 3 B Yes
Raspberrypi 3 B+ Partially (Contact shop if required) More info here.

Recommended sensors

AC Current sensor

  • SCT-013-000
  • SCT-006
  • SCT-019

Only current output CT are supported.

Stacking Configuration

General stacking information is described in the RPICT stacking page.
RPICT_Stacking

Software Configuration

Using a serial line terminal program one can configure the following: 

- Polling interval
- Output format (csv or emoncms)
- Calibration values (Voltage and Current)
- Voltage/current combinations for real power computation.
- Output channels

The documentation for serial configuration can be found on this page.
Over Serial Configuration - Sketch 2.2
Over Serial Configuration - Sketch 2.3
Over Serial Configuration - Sketch 2.4
Over Serial Configuration - Sketch 2.5
Over Serial Configuration - Sketch 2.6 & 2.7.1
Over Serial Configuration - Sketch 2.8

Over Serial Configuration - Sketch 3.0

The board can be configured with the online configurator.

Default Sketch V2.7.1.

Default Sketch V2.8.0.

Default Sketch V3.0.0.

Default Sketch V3.0.1.

Default Sketch V3.0.2.

(note boards are sold already flashed with latest stable sketch).

noOSC Sketch

The Default sketch allows up to 28 computation nodes to be run. If more are needed for higher stacks then we recommend to use the noOSC sketch. This is the same as the default sketch but Over Serial Configuration (OSC) as been removed to allow up to 40 nodes to be computed. Configuration has to be edited in the sketch.

noOSC Sketch v1.0
noOSC Sketch v1.1

Emoncms Config (Emonhub)

Make you read this first.

For default configuration.

       names = Power1, Power2, Power3, Power4, Power5, Power6, Power7, Power8

       scales = 1,1,1,1,1,1,1,1
       units = W,W,W,W,W,W,W,W

Python demo script

First of all make sure you have python-serial package installed 

$ sudo apt-get install python-serial

Then copy the following into an executable file and run it. 

#!/usr/bin/python2
import serial
ser = serial.Serial('/dev/ttyAMA0', 38400)

try:
       while 1:
            # Read one line from the serial buffer
            line = ser.readline()

            # Remove the trailing carriage return line feed
            line = line[:-2]

            # Create an array of the data
            Z = line.split(' ')

            # Print it nicely
            print ("----------")
            for i in range(len(Z)):
                if i==0:
                    print ("NodeID: %s" % Z[0])
                else:
                    print ("Power %d: %s W" % (i, Z[i]))
                       
except KeyboardInterrupt:
       ser.close()
