py-aosmith

This is an API Client for A. O. Smith iCOMM-enabled water heaters. If you can control your water heater using the A. O. Smith 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 A. O. Smith 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 A. O. Smith 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.

from py_aosmith import AOSmithAPIClient
from py_aosmith.models import OperationMode

# Initialize API client
client = AOSmithAPIClient("myemail@example.com", "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)

API Documentation

AOSmithAPIClient(email, password)

Parameters

Return value

Returns an instance of AOSmithAPIClient which can be used to invoke the below methods.

Get List of Devices

await client.get_devices()

Gets a list of water heaters linked with the A. O. Smith account. May only include devices which are known to be compatible with this library.

If your water heater can be controlled in the A. O. Smith mobile app, but is not included in the return value of this method, please open an issue so that support can be added.

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

Return value

None

Update mode

await client.update_mode(junction_id, mode, days)

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

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

Return value
