How-To

The following sample assumes that you're running the latest official Raspbian distribution, that you're logged in as root and that you haven't yet customized Raspbian to use SPI from a Python script. By default, the kernel module managing SPI communications is not loaded on Raspbian, so let's ensure that the 'spidev' device is available.

[email protected]:/# lsmodModule                  Size  Used by  snd_bcm2835            12808  0  snd_pcm                74834  1 snd_bcm2835  snd_seq                52536  0  snd_timer              19698  2 snd_seq,snd_pcm  snd_seq_device          6300  1 snd_seq  snd                    52489  5 snd_seq_device,snd_timer,snd_seq,snd_pcm,snd_bcm2835  snd_page_alloc          4951  1 snd_pcm  

If 'spidev' device is not listed, we need to remove it from the kernel module 'blacklist' so that it's automatically loaded on the next boot:

[email protected]:/# nano /etc/modprobe.d/raspi-blacklist.conf  

Put a hash character in front of the 'blacklist spi-bcm2708' statement and save the file:

#blacklist spi-bcm2708  

then, manually load the SPI device:

[email protected]:/# modprobe spidev  

The command should just complete without returning an error. Validate the list of modules:

[email protected]:/# lsmod  Module                  Size  Used by  spi_bcm2708             4401  0  spidev                  5136  0  snd_bcm2835            12808  0  snd_pcm                74834  1 snd_bcm2835  snd_seq                52536  0  snd_timer              19698  2 snd_seq,snd_pcm  snd_seq_device          6300  1 snd_seq  snd                    52489  5 snd_seq_device,snd_timer,snd_seq,snd_pcm,snd_bcm2835  snd_page_alloc          4951  1 snd_pcm  

The 'spidev' device should now be available.

Next, install the 'git' package. It will be needed to install other packages from Github.

apt-get install git-core  

Install the 'python-dev' package. It will be needed to compile the 'py-spidev' package.

apt-get install python-dev  

Download and compile the 'py-spidev' package.

[email protected]:/# cd /home  [email protected]:/home# git clone git://github.com/doceme/py-spidev  [email protected]:/home# cd py-spidev/  [email protected]:/home# python setup.py install  

At this point, SPI is available from Python 2.7. Assuming that you have wired the MCP3008 to the Raspberry Pi's SPI bus using CE0 as the 'chip select' pin, you can read all eight analog inputs using the following Python script.

[email protected]:/home# nano adc.py  

Paste the script below in the editor and save it.

import spidev  import time    spi = spidev.SpiDev()  spi.open(0,0)    # read SPI data from MCP3008 chip, 8 possible adc's (0 thru 7)  def readadc(adcnum):          if ((adcnum > 7) or (adcnum < 0)):                  return -1          r = spi.xfer2([1,(8 adcnum)<<4,0])          adcout = ((r[1]&3) << 8)   r[2]          return adcoutwhile True:          for adcInput in range(0,8):                  print "ADC(", adcInput,")=", readadc(adcInput)          time.sleep(1)  

To execute the script

[email protected]:/home# python adc.py  

Sample output using a 10K Ohm trimpot connected to the ADC's pin 3 and all other pins pulled down to ground using a 10k resistor.

ADC( 0 )= 0  ADC( 1 )= 0  ADC( 2 )= 0  ADC( 3 )= 507  ADC( 4 )= 0  ADC( 5 )= 0  ADC( 6 )= 0  ADC( 7 )= 0  

Credits go to Jeremy for his work on the 'py-spidev' Python module which makes working with the MCP3008 straight forward. Alternatively, checkout wiringPi's SPI functions if you prefer using a 'C' API.

SONOFF® Dual Channel WIFI APP Remote Control Switch Socket Module 250V For Smart Home (Sonoff dual ch switch)
Description:

Sonoff Dual is a WiFi based 2 gang switch that can connect and independently control two connected appliances or lights. This simply means 1 Sonoff Dual control switch equals to 2 Sonoff basic switches! Sonoff Dual 2 gang light switch inherits Sonoff Basic switch’s advantages such as easy installation and operation, quick WiFi access, remote control through APP EweLink.

In the application eWeLink, available on both iOS and Android, users can independently turn on/off each of the two connected devices. But the button on Sonoff Dual 2 gang WiFi light switch is not an ON/OFF toggle switch, it is only a WiFi pairing button. Users can set single/repeat/countdown timing schedules to turn on/off at a specified time, and also share with others so that they can control together.

Works With Amazon Alexa

You can ask Alexa to turn on/off Sonoff Dual.

Standard voice control commands phrases for Sonoff Dual (if you just say the device name, Alexa will turn on/off all the 2 gangs immediately):

Alexa, turn on {deviceName}
Alexa, turn off {deviceName}

Alexa, turn on {deviceName} {gangName}
Alexa, turn off {deviceName} {gangName}

Explanation: if the device name of your Sonoff Dual is "My Switch", the gang name is "Gang 1", then you can control with "Alexa, turn on My Switch Gang 1".

Input section:
DC +: Connect the power supply positive (according to the relay voltage)
DC-: Connect the power supply negative
CH1: 1 relay module signal trigger terminal (low level trigger active)
CH2: 2 relay module signal trigger terminal (low level trigger active)
CH3: 2 relay module signal trigger terminal (low level trigger active)
CH4: 2 relay module signal trigger terminal (low level trigger active)

High and low meaning:

High-level trigger refers to the signal trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger side voltage or trigger to reach the trigger Voltage, the relay is pull.

Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive terminal of the power supply. When the voltage is low enough to trigger, the relay is pulled in, The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.

433Mhz Geekcreit® DC 12V 10A Relay 1Channel Wireless RF Remote Control Relay (1 channel relay remote)
Description:

It is a learning code wireless remote control switch (receiver), the output way /working way can be changed as you like. It is easy to match the transmitter. A Relay which can make the equipment turn or reverse, on/off. The volume is small and the performance is stable and reliable, with high receive sensitivity.

Features:

Easy to use.
Operating Voltage: DC12V
Maximum Load: 10A
Operating Frequency: 433MHZ
Receiver Sensitivity: -100dBm
Encoding Type: learning code
Board Size: Approx. 5.3x3.1cm/ 2.09x1.22"

Relay rating:

  • 10A 250VAC
  • 10A 125VAC
  • 10A 30VDC
  • 10A 28VDC

To check compatibility of a new remote with the receiver. Simply press the button on the remote, if the receiver flashes, but does not Triger the relay. The remote will be compatible, and you can start the programing process

To add a remote, press the button on receiver momentarily. The red light will come on. Then press the button on the remote that you want to program in. The red light will start flashing. After 4 flashes in will stop, and the button will be programmed in.

For the setting to take effect, the board needs to be disconnected from it’s power supply. The bellow settings will be done to the 3 headers and bridge pin on the receiver board, above the push button.

  • With the header removed, the On button will switch the relay on, and the off button will in turn switch the relay off.
  • With the header on Pin 1-2. Both Buttons will become momentary. And only hold the relay in place as long as they are pressed in.
  • With the header on Pin 2-3. Each button will be able to switch the relay on and off individually. You will however not be able to switch the button off with the “off” button, if you switched it on with the “on” button. And vise versa.


Package Includes:

1 x Learning Code Receiver Relay
1 x Remote Control
