pyanova

An Anova Precision Cooker (Sous Vide) Bluetooth API Python Wrapper

Descirption

This is a Python wrapper of the Anova Precision Cooker (Sous Vide) API via the Bluetooth LE connection. Under the hood, it utilizes peplin/pygatt for the Bluetooth LE communications.

The library is tested on C.H.I.P with Debian + Python 2.7 and Python 3.4

Acknowledgements

• This work relies heavily on the researches from dfrankland/sous-vide, a very nice API for Node JS. Commands used in pyanova are based on its research on the Android APP APK.
• Bluetooh LE communication is made easy with pygatt

Installation

Prerequisites

• pygatt - specifically, it uses the gatttool backend
• bluez - specifically, the gatttool backend requires hcitool, make sure you can find hcitool in your system.

Install using Python pip

Once the prerequisite are satisfied, you can install pyanova with pip: pip install pyanova

Usage

The GATTTool backend normally requires root permission. Hence you might need to run your program with root permission or setup passwordless sudo for 'hcitool'.

Automode

You can initialize PyAnova easily with automode which will automatically discover and connect to the first available Anova device

from pyanova import pyanova

pa = pyanova.PyAnova()
pa.get_status()

Manual mode

Alternatively, you can fully control the discover and connect phrases of an PyAnova object

from pyanova import pyanova

pa = pyanova.PyAnova(auto_connect=False)
devices = pa.discover(list_all=False, timeout=3)
pa.connect_device(devices[0])
pa.get_status()

TODO

• Unit tests
• Autogen docs
• Probably swtich to pygattlib?
