Python API and command line tool for talking to the Nest™ Thermostat
Project description
Installation
[sudo] pip install python-nest
Usage
Module
You can import the module as nest.
import nest
username = 'joe@user.com'
password = 'swordfish'
napi = nest.Nest(username, password)
for structure in napi.structures:
print 'Structure %s' % structure.name
print ' Away: %s' % structure.away
print ' Devices:'
for device in structure.devices:
print ' Device: %s' % device.name
print ' Temp: %0.1f' % device.temperature
# The Nest object can also be used as a context manager
with nest.Nest(username, password) as napi:
for device in napi.devices:
device.temp = 23
# Weather data is also availible under structure or device
# The api is the same from either
structure = napi.structures[0]
time_str = structure.weather.current.datetime.strftime('%Y-%m-%d %H:%M:%S')
print 'Current Weather at %s:' % time_str
print ' Condition: %s' % structure.weather.current.condition
print ' Temperature: %s' % structure.weather.current.temperature
print ' Humidity: %s' % structure.weather.current.humidity
print ' Wind Dir: %s' % structure.weather.current.wind.direction
print ' Wind Azimuth: %s' % structure.weather.current.wind.azimuth
print ' Wind Speed: %s' % structure.weather.current.wind.kph
# NOTE: Hourly forecasts do not contain a "contidion" its value is `None`
# Wind Speed is likwise `None` as its generally not reported
print 'Hourly Forcast:'
for f in structure.weather.hourly:
print ' %s:' % f.datetime.strftime('%Y-%m-%d %H:%M:%S')
print ' Temperature: %s' % f.temperature
print ' Humidity: %s' % f.humidity
print ' Wind Dir: %s' % f.wind.direction
print ' Wind Azimuth: %s' % f.wind.azimuth
# NOTE: Daily forecasts temperature is a tuple of (low, high)
print 'Daily Forcast:'
for f in structure.weather.daily:
print ' %s:' % f.datetime.strftime('%Y-%m-%d %H:%M:%S')
print ' Condition: %s' % structure.weather.current.condition
print ' Low: %s' % f.temperature[0]
print ' High: %s' % f.temperature[1]
print ' Humidity: %s' % f.humidity
print ' Wind Dir: %s' % f.wind.direction
print ' Wind Azimuth: %s' % f.wind.azimuth
print ' Wind Speed: %s' % structure.weather.current.wind.kph
# NOTE: By default all datetime objects are timezone unaware (UTC)
# By passing `local_time=True` to the `Nest` object datetime objects
# will be converted to the timezone reported by nest. If the `pytz`
# module is installed those timezone objects are used, else one is
# synthesized from the nest data
napi = nest.Nest(username, password, local_time=True)
print napi.structures[0].weather.current.dateimte.tzinfo
In the API all temperature values are in degrees celsius. Helper functions for conversion are in the utils module:
from nest_thermostat import utils as nest_utils
temp = 23.5
fahrenheit = nest_utils.c_to_f(temp)
temp == nest_utils.f_to_c(fahrenheit)
The utils function use decimal.Decimal to ensure precision.
For “advanced” usage such as token caching, use the source, luke!
Command line
usage: nest [-h] [--conf FILE] [--token-cache TOKEN_CACHE_FILE] [-t TOKEN]
[-u USER] [-p PASSWORD] [-c] [-s SERIAL] [-i INDEX]
{temp,fan,mode,away,target,humid,target_hum,show} ...
Command line interface to Nest™ Thermostats
positional arguments:
{temp,fan,mode,away,target,humid,target_hum,show}
command help
temp show/set temperature
fan set fan "on" or "auto"
mode show/set current mode
away show/set current away status
target show current temp target
humid show current humidity
target_hum show/set target humidity
specify target humidity value or auto to auto-select a
humidity based on outside temp
show show everything
optional arguments:
-h, --help show this help message and exit
--conf FILE config file (default ~/.config/nest/config)
--token-cache TOKEN_CACHE_FILE
auth access token
-t TOKEN, --token TOKEN
auth access token cache file
-u USER, --user USER username for nest.com
-p PASSWORD, --password PASSWORD
password for nest.com
-c, --celsius use celsius instead of farenheit
-s SERIAL, --serial SERIAL
optional, specify serial number of nest thermostat to
talk to
-i INDEX, --index INDEX
optional, specify index number of nest to talk to
examples:
nest --user joe@user.com --password swordfish temp 73
nest --user joe@user.com --password swordfish fan auto
nest --user joe@user.com --password swordfish target_hum 35
A configuration file can also be specified to prevent username/password repitition.
[DEFAULT]
user = joe@user.com
password = swordfish
token_cache = ~/.config/nest/cache
The [DEFAULT] section may also be named [nest] for convience.
