Usage

import asyncio
from datetime import datetime

from aiohttp import ClientSession

from aioflo import async_get_api


async def main() -> None:
    """Run!"""
    api = await async_get_api("<EMAIL>", "<PASSWORD>")

    # Get user account information:
    user_info = await api.user.get_info()
    a_location_id = user_info["locations"][0]["id"]

    # Get location (i.e., device) information:
    location_info = await api.location.get_info(a_location_id)

    # Get device information
    first_device = location_info["devices"][0]
    first_device_id = first_device["id"]
    device_info = await api.device.get_info(first_device_id)

    # Run a health test
    health_test_response = await api.device.run_health_test(first_device_id)

    # Close the shutoff valve
    close_valve_response = await api.device.close_valve(first_device_id)

    # Open the shutoff valve
    open_valve_response = await api.device.open_valve(first_device_id)

    # Get consumption info between a start and end datetime (location-wide aggregate):
    consumption_info = await api.water.get_consumption_info(
        a_location_id,
        datetime(2020, 1, 16, 0, 0),
        datetime(2020, 1, 16, 23, 59, 59, 999000),
    )

    # Scope consumption to a single device. Pass device_mac_address when a location
    # has multiple Flo devices; omit it for the location-wide total:
    device_consumption = await api.water.get_consumption_info(
        a_location_id,
        datetime(2020, 1, 16, 0, 0),
        datetime(2020, 1, 16, 23, 59, 59, 999000),
        device_mac_address=first_device["macAddress"],
    )

    # Get various other metrics related to water usage:
    metrics = await api.water.get_metrics(
        first_device["macAddress"],
        datetime(2020, 1, 16, 0, 0),
        datetime(2020, 1, 16, 23, 59, 59, 999000),
    )

    # Get recent Flo Detect water-flow events (near-real-time usage):
    events = await api.flodetect.get_events(
        first_device["macAddress"],
        to=datetime(2026, 7, 12, 10, 25, 4),
        limit=20,
    )

    # Set the device in "Away" mode:
    await set_mode_away(a_location_id)

    # Set the device in "Home" mode:
    await set_mode_home(a_location_id)

    # Set the device in "Sleep" mode for 120 minutes, then return to "Away" mode:
    await set_mode_sleep(a_location_id, 120, "away")


asyncio.run(main())

Moen SSO (Cognito) auth

The current Moen Smartwater app authenticates against Moen's SSO endpoint rather than the legacy Flo users/auth flow. use_sso=True opts into it: the access token is sent to api-gw.meetflo.com as a bearer token and is refreshed on expiry and on a 401, falling back to a full login if the refresh token is rejected.

api = await async_get_api("<EMAIL>", "<PASSWORD>", use_sso=True)

The legacy flow is the default and is unchanged. The legacy endpoint still works, so this is cover for it being retired rather than a fix for a current failure.

By default, the library creates a new connection to Flo with each coroutine. If you are calling a large number of coroutines (or merely want to squeeze out every second of runtime savings possible), an aiohttp ClientSession can be used for connection pooling:

import asyncio
from datetime import datetime

from aiohttp import ClientSession

from aioflo import async_get_api


async def main() -> None:
    """Create the aiohttp session and run the example."""
    async with ClientSession() as session:
        api = await async_get_api("<EMAIL>", "<PASSWORD>", session=session)

        # Tell Flo to get updated data from the device
        ping_response = await api.presence.ping()

        # Get user account information:
        user_info = await api.user.get_info()
        a_location_id = user_info["locations"][0]["id"]

        # Get location (i.e., device) information:
        location_info = await api.location.get_info(a_location_id)

        # Get device information
        first_device = location_info["devices"][0]
        first_device_id = first_device["id"]
        device_info = await api.device.get_info(first_device_id)

        # Run a health test
        health_test_response = await api.device.run_health_test(first_device_id)

        # Close the shutoff valve
        close_valve_response = await api.device.close_valve(first_device_id)

        # Open the shutoff valve
        open_valve_response = await api.device.open_valve(first_device_id)

        # Get consumption info between a start and end datetime (location-wide aggregate):
        consumption_info = await api.water.get_consumption_info(
            a_location_id,
            datetime(2020, 1, 16, 0, 0),
            datetime(2020, 1, 16, 23, 59, 59, 999000),
        )

        # Scope consumption to a single device. Pass device_mac_address when a location
        # has multiple Flo devices; omit it for the location-wide total:
        device_consumption = await api.water.get_consumption_info(
            a_location_id,
            datetime(2020, 1, 16, 0, 0),
            datetime(2020, 1, 16, 23, 59, 59, 999000),
            device_mac_address=first_device["macAddress"],
        )

        # Get various other metrics related to water usage:
        metrics = await api.water.get_metrics(
            first_device["macAddress"],
            datetime(2020, 1, 16, 0, 0),
            datetime(2020, 1, 16, 23, 59, 59, 999000),
        )

        # Get recent Flo Detect water-flow events (near-real-time usage):
        events = await api.flodetect.get_events(
            first_device["macAddress"],
            to=datetime(2026, 7, 12, 10, 25, 4),
            limit=20,
        )

        # Set the device in "Away" mode:
        await set_mode_away(a_location_id)

        # Set the device in "Home" mode:
        await set_mode_home(a_location_id)

        # Set the device in "Sleep" mode for 120 minutes, then return to "Away" mode:
        await set_mode_sleep(a_location_id, 120, "away")
