Automate is a general purpose automatization library for Python. Its objective is to offer convenient and robust object-oriented programming framework for complex state machine systems. Automate can be used to design complex automation systems, yet it is easy to learn and fun to use. It was originally developed with home robotics/automatization projects in mind, but is quite general in nature and one could find applications from various fields that could take advantage of Automate. Automate can be embedded in other Python software as a component, which runs its operations in its own threads.

Highlights:

• Supported hardware:

  • Raspberry Pi GPIO input/output ports (automate-rpio extension via RPIO library)

  • Arduino analog and digital input/output ports (automate-arduino extension via pyFirmata library)

  • Easy to write extensions to support other hardware

• System state saving and restoring via serialization

• Intelligent design:

  • Comprehensively tested via py.test unit/integration tests

  • Takes advantage of Traits library, especially its notification system.

  • IPython console to monitor, modify and control system on-the-fly

  • Versatile function/callable library to write state program logic

• RPC and Websocket interfaces (provided by automate-rpc and automate-webui) to connect between other applications or other Automate systems.

• Comprehensive and customizable Web User Interface via automate-webui extension.

• UML graphs can be drawn automaticlaly of the system (as can be seen in the examples of this documentation)

Example

Let’s take a look at a small Automate program as an example, which uses also automate-rpio extension.

from automate import *

class MySystem(System):
    # HW swtich connected Raspberry Pi GPIO port 1
    hardware_switch = RpioSensor(port=1)
    # Switch that is controllable, for example, from WEB interface
    web_switch = UserBoolSensor()
    # Lamp relay that switches lamp on/off, connected to GPIO port 2
    lamp = RpioActuator(port=2)
    # Program that controls the system behaviour
    program = Program(
        active_condition=Or('web_switch', 'hardware_switch'),
        on_activate=SetStatus('lamp', True)
    )


my_system = MySystem()

This simple example has two sensors hardware_switch, web_switch, actuator (lamp) and a program that contains logic what to do and when. Here, lamp is switched on if either web_switch or hardware_switch has status True.

Installing Automate

Automate can be installed like ordinary python package. I recommend installation in within virtual environment (see virtualenv).

1. (optional): Create and start using virtualenv:

   mkvirtualenv automate
   workon automate

2. Install from pypi:

   pip install automate

3. If you want to install some extensions too, you may also run:

   pip install automate-webui
   pip install automate-rpc
   pip install automate-arduino
   pip install automate-rpio

Optionally, you could install also by cloning GIT repository and installing manually:

git clone https://github.com/tuomas2/automate.git
cd automate
./setup.py install
