Library Usage

from pyrheem import RheemEcoNetAPI

# Initialize and login
api = RheemEcoNetAPI("[e-mail]", "password")

if api.login() and api.get_all_data():
    # List all water heaters
    for serial, heater in api.water_heaters.items():
        print(f"{heater.display_name}: {heater.setpoint}F")

    # Get first water heater
    heater = list(api.water_heaters.values())[0]

    # Set temperature
    api.set_temperature(heater, 120)

    # Set mode
    api.set_mode(heater, "energy")  # or "performance"

    # Enable/disable
    api.set_enabled(heater, True)

    # Cleanup
