pyvesync is a library to manage Etekcity Switches

Project description

pyvesync build status

pyvesync is a library to manage VeSync compatible smart home devices.


Install the latest version from pip:

pip install pyvesync

Supported Devices

  1. Etekcity Voltson Smart WiFi Outlet (7A model ESW01-USA)
  2. Etekcity Voltson Smart WiFi Outlet (10A model ESW01-EU)
  3. Etekcity Voltson Smart Wifi Outlet (10A model ESW03-USA)
  4. Etekcity Voltson Smart WiFi Outlet (15A model ESW15-USA)
  5. Etekcity Two Plug Outdoor Outlet (ESO15-TB) (Each plug is a separate object, energy readings are for both plugs combined)
  6. Etekcity Smart WiFi Light Switch (model ESWL01)
  7. Levoit Smart Wifi Air Purifier (LV-PUR131S)
  8. Etekcity Soft White Dimmable Smart Bulb (ESL100)


To start with the module:

from pyvesync import VeSync

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

my_switch = manager.outlets[0]
# Turn on the first switch
# Turn off the first switch

# Get energy usage data

# Display outlet device information
for device in manager.outlets:


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] = [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

Manager API

VeSync.get_devices() - Returns a list of devices

VeSync.login() - Uses class username and password to login to VeSync

VeSync.update() - Fetch updated information about devices

VeSync.update_all_devices() - Fetch details for all devices (run VeSyncDevice.update())

VeSync.update_energy(bypass_check=False) - Get energy history for all outlets - Builds week, month and year nested energy dictionary. Set bypass_check=True to disable the library from checking the update interval

Device API

VeSyncDevice.turn_on() - Turn on the device

VeSyncDevice.turn_off() - Turn off the device

VeSyncDevice.update() - Fetch updated information about device

VeSyncDevice.active_time - Return active time of the device in minutes

VeSyncDevice.get_config() - Retrieve Configuration data such as firmware version for device and store in the VeSyncDevice.config dictionary

VeSyncDevice.firmware_update - Return true if Firmware has update available. VeSyncDevice.get_config() must be called first

Outlet Specific Energy API

VeSyncOutlet.update_energy(bypass_check=False) - Get outlet energy history - Builds week, month and year nested energy dictionary. Set bypass_check=True to disable the library from checking the update interval

VeSyncOutlet.energy_today - Return current energy usage in kWh

VeSyncOutlet.power - Return current power in watts of the device

VeSyncOutlet.voltage - Return current voltage reading

VesyncOutlet.weekly_energy_total - Return total energy reading for the past week in kWh, starts 12:01AM Sunday morning

VesyncOutlet.monthly_energy_total - Return total energy reading for the past month in kWh

VesyncOutlet.yearly_energy_total - Return total energy reading for the past year in kWh

Model ESW15-USA 15A/1800W API

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 Functions

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

VeSyncFan.air_quality - Return air quality reading

VeSyncFan.auto_mode() - Change mode to auto

VeSyncFan.manual_mode() - Change fan mode to manual with fan level 1

VeSyncFan.sleep_mode() - Change fan mode to sleep

VeSyncFan.change_fan_speed(speed) - Change fan speed with level 1, 2 or 3

VeSyncFan.screen_status - Get Status of screen on/off

Smart Light Bulb API

VeSyncBulb.set_brightness(brightness) - Set bulb brightness values from 1 - 100


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

The object includes 3 nested dictionaries week, month, and year that contain detailed weekly, monthly and yearly data['week']['energy_consumption_of_today']['week']['cost_per_kwh']['week']['max_energy']['week']['total_energy']['week']['data'] # which itself is a list of values

Integration with Home Assistant

This library is integrated with Home Assistant and documentation can be found at The library version included with Home Assistant may lag behind development compared to this repository so those wanting to use the latest version can do the following to integrate with HA.

  1. Add a custom_components directory to your Home Assistant configuration directory
  2. Add a vesync directory as a directory within custom_components
  3. Add to the vesync directory
  4. Add to the vesync directory
  5. Add manifest.json to the vesync directory
  6. Add the following config to your Home Assistant configuration.yaml file:
  1. Restart Home Assistant

The custom_components directory should include the following files:


The version of the library defined in manifest.json should now get loaded within Home Assistant.
