Usage

To start with the module:

from pyvesync_v2 import VeSync

manager = VeSync("EMAIL", "PASSWORD", time_zone=DEFAULT_TZ)
manager.login()

# Get/Update Devices from server - populate device lists
manager.update()

my_switch = manager.outlets[0]
# Turn on the first switch
my_switch.turn_on()
# Turn off the first switch
my_switch.turn_off()

# Get energy usage data
manager.update_energy()

# Display outlet device information
for device in manager.outlets:
    device.display()

Configuration

The time_zone argument is optional but the specified time zone must match time zone in the tz database (IANNA Time Zone Database), see this link for reference: tz database. The time zone determines how the energy history is generated for the smart outlets, i.e. for the week starts at 12:01AM Sunday morning at the specified time zone. If no time zone or an invalid time zone is entered the default is America/New_York

#Devices are respectively located in their own lists that can be iterated over
manager.outlets = [VeSyncOutletObjects]
manager.switches = [VeSyncSwitchObjects]
manager.fans = [VeSyncFanObjects]
manger.bulbs = [VeSyncBulbObjects]

If outlets are going to be continuously polled, a custom energy update interval can be set - The default is 6 hours (21600 seconds)

manager.energy_update_interval = time # time in seconds

Example Usage

Get electricity metrics of outlets

for s in manager.outlets:
  s.update_energy(check_bypass=False) # Get energy history for each device

API Details

Model ESW15-USA 15A/1800W Methods

The rectangular smart switch model supports some additional functionality on top of the regular api call

VeSyncOutlet.turn_on_nightlight() - Turn on the nightlight

VeSyncOutlet.turn_off_nightlight() - Turn off the nightlight

Air Purifier LV-PUR131S Methods

VeSyncFan.fan_level - Return the level of the fan (1-3) or 0 for off

VeSyncFan.filter_life - Return the percentage of filter life remaining

More detailed data is available within the VesyncOutlet by inspecting the VesyncOutlet.energy dictionary.

The VesyncOutlet.energy object includes 3 nested dictionaries week, month, and year that contain detailed weekly, monthly and yearly data

VesyncOutlet.energy['week']['energy_consumption_of_today']
VesyncOutlet.energy['week']['cost_per_kwh']
VesyncOutlet.energy['week']['max_energy']
VesyncOutlet.energy['week']['total_energy']
VesyncOutlet.energy['week']['data'] # which itself is a list of values
