USMS

An unofficial Python library to interface with your USMS account and smart meters.

Getting Started

Installation

python -m pip install usms

Quickstart

python -m usms --help

usage: __main__.py [-h] [-l LOG] -u USERNAME -p PASSWORD [-m METER] [--unit] [--consumption] [--credit]

options:
  -h, --help            show this help message and exit
  -l LOG, --log LOG
  -u USERNAME, --username USERNAME
  -p PASSWORD, --password PASSWORD
  -m METER, --meter METER
  --unit
  --consumption
  --credit

[!NOTE] The username parameter is the login ID that you use to log-in on the USMS website/app, i.e. your IC Number.

As an example, you can use the following command to get the current remaining unit:

python -m usms -u <ic_number> -p <password> -m <meter> --unit

You can also use environment variables for the login information:

export USMS_USERNAME="<ic_number>"
export USMS_PASSWORD="<password>"
python -m usms -m <meter> --unit

Or:

USMS_USERNAME="<ic_number>" USMS_PASSWORD="<password>" python -m usms -m <meter> --unit

Usage

from usms import USMSAccount
from datetime import datetime

username = "01001234" # your ic number
password = "hunter1"

# initialize the account
account = USMSAccount(username, password)

# print out the account information
print(account.reg_no)
print(account.name)
print(account.contact_no)
print(account.email)

# print out info on all meters under the account
for meter in account.meters:
    print(meter.no)
    print(meter.type)
    print(meter.address)
    print(meter.remaining_unit)
    print(meter.remaining_credit)

# get the number of the first meter
meter_no = account.meters[0].no

# to get info from a specific meter
meter = account.get_meter(meter_no)

# getting hourly breakdown of today's consumptions
date = datetime.now()
hourly_consumptions = meter.get_hourly_consumptions(date)
print(hourly_consumptions)

# getting daily breakdown of this month's comsumptions
daily_consumptions = meter.get_daily_consumptions(date)
print(daily_consumptions)

# get yesterday's total consumption
date = date.replace(day=date.day-1)
print(meter.get_total_day_consumption(date))

# get last month's total cost based un total consumption
date = date.replace(month=date.month-1)
print(meter.get_total_month_cost(date))

To-Do

Developing

• This project follows the Conventional Commits standard to automate Semantic Versioning and Keep A Changelog with Commitizen.
• Run poe from within the development environment to print a list of Poe the Poet tasks available to run on this project.
• Run uv add {package} from within the development environment to install a run time dependency and add it to pyproject.toml and uv.lock. Add --dev to install a development dependency.
• Run uv sync --upgrade from within the development environment to upgrade all dependencies to the latest versions allowed by pyproject.toml. Add --only-dev to upgrade the development dependencies only.
• Run cz bump to bump the package's version, update the CHANGELOG.md, and create a git tag. Then push the changes and the git tag with git push origin main --tags.
