The `waterfurnace` component communicates with the WaterFurnace
Symphony website's WebSocket to show you many of the sensors in your
system. While not an official API, this is the same backend the
Symphony website is based on, and should be reasonably stable.

The sensors provided include:
 - Thermostat Setpoint
 - Thermostat Current Temp
 - Leaving Air Temp
 - Entering Water Loop Temp
 - Current Humidity
 - Current Humidity Setpoint
 - Total system power (in Watts)
 - Furnace Mode

To use Waterfurnace in your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
waterfurnace:
  username: you@example.com
  password: secr3tpassword
  unit: 0123456789AB
```

{% configuration %}
username:
    description: The email address for your Symphony WaterFurnace account
    required: true
    type: string
password:
    description: The password for your Symphony WaterFurnace account
    required: true
    type: string
unit:
    description: The unit serial number for your WaterFurnace
    required: true
    type: string
{% endconfiguration %}

The WebSocket interface used by this module requires active polling,
otherwise the server side shuts down the connection. By default, this
polling is happening every 10 seconds. All sensors are updated during
every polling cycle.

While this is communicating with a thermostat, geothermal systems
operate most efficiently when setbacks are not used, and the home is
kept at a constant temperature. It remains useful to collect the data
from the system to understand its performance, but a full climate
interface won't be implemented.
