py-aosmith 1.0.18

A Python client library for A. O. Smith water heaters

py-aosmith

This is an API Client for A. O. Smith iCOMM-enabled water heaters. If you can control your water heater using the iCOMM mobile app (iOS/Android), then it should be compatible with this library.

If your water heater is not working with this library, but it can be controlled using the iCOMM mobile app, please open an issue so that support can be added.

Similarly, if your water heater is working with this library, but is not listed here, please open an issue so it can be added to the list.

Installation

To install the latest release from PyPI, run pip3 install py-aosmith.

Quick Start

You will need a compatible water heater which is already connected to Wi-Fi and linked to your iCOMM account.

This example initializes the API client and gets a list of water heaters linked to the account. Then, for each water heater, it updates the setpoint to 120 degrees.

import asyncio

from py_aosmith import AOSmithAPIClient
from py_aosmith.models import OperationMode

async def main():
    # Initialize API client
    client = AOSmithAPIClient("[e-mail]", "mypassword")

    # Get list of water heaters linked to the account
    devices = await client.get_devices()

    # Loop through the registered water heaters
    for device in devices:
        # Update the setpoint to 120 degrees
        await client.update_setpoint(device.junction_id, 120);

        # Set the operation mode to heat pump
        await client.update_mode(device.junction_id, OperationMode.HEAT_PUMP)

    await client.close()

asyncio.run(main())

Update setpoint

await client.update_setpoint(junction_id, setpoint)

Updates the setpoint (target water temperature) of the water heater.

When using this method, the setpoint cannot be adjusted above the temperature_setpoint_maximum from the return value of get_devices(). To increase the maximum, manually adjust the setpoint using the buttons on the water heater.

Parameters

Parameter	Description
junction_id	Unique ID of the water heater, obtained from get_devices()
setpoint	New target temperature to set

Return value

None

Update mode

await client.update_mode(junction_id, mode, days, hot_water_plus_level)

Sets the operation mode of the water heater. To determine the list of modes supported by your water heater, check supported_modes in the Device object returned by get_devices().

Parameters

Parameter	Description
junction_id	Unique ID of the water heater, obtained from get_devices()
mode	New operation mode to set. Must be a member of the OperationMode enum and must be a supported mode from supported_modes.
days	Optional. Number of days after which the device will automatically exit this mode. Only works for modes where has_day_selection from supported_modes is True.
hot_water_plus_level	Optional. Set the level for the Hot Water+ feature from 0-3, if supported by the device and operation mode. If unsupported, an AOSmithInvalidParametersException will be raised.

Return value

None

Get energy use data

await client.get_energy_use_data(junction_id)

Gets energy use history data from the water heater.

Parameters

Parameter	Description
junction_id	Unique ID of the water heater, obtained from get_devices()

Return value

EnergyUseData(
    lifetime_kwh=234.309,
    history=[
        EnergyUseHistoryEntry(
            date='2023-12-09T04:00:00.000Z',
