An interface to tinyos.com TOSR0x relay modules.

Project description

A Python module for communicating with ‘TOSR0x’ relay controllers available at [tinyosshop.com](http://www.tinyosshop.com/index.php?route=product/product&product_id=365) and other online retailers.

Note: as of v0.6.0 this module only supports Python 3.4+.

Functionality

  • Detect TOSR0x USB and WiFi devices.
  • Set relay states.
  • Query relay states.
  • Query temperature (on supported models).

Requirements

  • Python serial module (should be installed by default)

Installation

Use setup.py:

python setup.py install

If using Debian or a derivative (Ubuntu) additional USB permissions may be required:

Add the user to the ‘dialout’ group:

$ sudo usermod -G dialout -a <username>

Add a udev rules file to allow access to usb devices:

$ cat /etc/udev/rules.d/50-usb.rules # allow access to usb devices for users in dialout group SUBSYSTEM==”usb”, MODE=”0666”, GROUP=”dialout”

Usage

Call the handler function to return a list of tosr0x objects:

>import tosr0x >th = tosr0x.handler()

Testing USB serial device on /dev/ttyUSB0 Testing USB serial device on /dev/ttyUSB1 Testing USB serial device on /dev/ttyUSB2 Testing USB serial device on /dev/ttyUSB3 TOSR0x device found on /dev/ttyUSB3

>myTosr0x = th[0] >print myT0sr0x

<tosr0x.relayModule instance at 0xb68be46c>

By default the handler scans all USB ports for compatible tosr0x devices. You can also specify a range of ports to scan:

>th = tosr0x.handler(devicePath=[‘/dev/ttyUSB3’])

Testing USB serial device on /dev/ttyUSB3 TOSR0x device found on /dev/ttyUSB3

Usually all relays on the module are cycled at initialisation to determine the relay count. You can specify a relay count to prevent this:

>th = tosr0x.handler(devicePath=[‘/dev/ttyUSB3’], relayCount=4)

Testing USB serial device on /dev/ttyUSB3 TOSR0x device found on /dev/ttyUSB3

It is also possible to use the class directly without using the handler:

FOR SERIAL: >import serial >import tosr0x >sd=serial.Serial(‘/dev/ttyUSB0’, timeout=0.1) >myTosr0x=tosr0x.relayModule(sd) #Num relays not specified in this example

FOR WIFI: >import tosr0x >myTosr0x = tosr0x.relayModule( (‘192.168.1.2’,2000), 2) #Module of 2 relays

Set relay states to either 0 or 1:

>myTosr0x.set_relay_position(1,1) True

>myTosr0x.set_relay_position(2,0) True

(Note: relay numbering starts at 1. Set the state of all relays by using relay number 0.)

Get relay positions, (returned as a dict {relay : state}):

>myTosr0x.get_relay_positions() {1: 1, 2: 0}

Get Ambient Temperaure n Celsius degree for modules supporting a temperature probe:

>myTosr0x.get_temperature() 23.94

Projects

  • James Stewart (@amorphic) uses to _tosr0x_ to implement an Environmental Controller in [braubuddy](http://braubuddy.org), a temperature monitoring framework.
  • Alex Roche (@alexroche) is using _tosr0x_ with WIFI option to control blinds through openremote controller running on a Raspberry Pi.
