Nefit Easy™ .NET Standard Library

.NET Standard client library for the Nefit Easy smart thermostat.

PLEASE READ BEFORE USE!

Use this library in moderation: don't flood the backend with new connections made every X seconds. Instead, if you want to poll the backend for data, create a connection once and reuse it for each command. In the end, it's your own responsibility to not get blocked because of excessive (ab)use.

Disclaimer

The implementation of this library is based on an other github user larscom. He put really great work in it. The only thing I did is creating a dotnet standard package from it so it can be used in dotnet core projects.

Official Disclaimer from larscom:

The implementation of this library is based on reverse-engineering the communications between the apps and the backend, plus various other bits and pieces of information. It is not based on any official information given out by Nefit/Bosch, and therefore there are no guarantees whatsoever regarding the safety of your devices and/or their settings, or the accuracy of the information provided.

Examples

Create Client & Connect

Create a client and get the owner info.

INefitEasyClient client = new NefitEasyClient(new NefitEasyCredentials {
  SerialNumber = "",
  AccessKey = "",
  Password = ""
});
    
await client.ConnectAsync().ConfigureAwait(false);
    
if (client.Status == NefitConnectionStatus.Connected)
{
  IEnumerable<string> owner = await client.GetOwnerInfoAsync().ConfigureAwait(false);
}    

Subscribe to Connection Events

INefitEasyClient client = new NefitEasyClient(new NefitEasyCredentials {
  SerialNumber = "",
  AccessKey = "",
  Password = ""
});

client.OnStatusChanged += (sender, status) =>
{
    switch (status)
    {
       case NefitConnectionStatus.Connecting:
           break;
       case NefitConnectionStatus.Connected:
           break;
       case NefitConnectionStatus.AuthenticationTest:
           break;
       case NefitConnectionStatus.InvalidCredentials:
           break;
       case NefitConnectionStatus.Disconnecting:
           break;
       case NefitConnectionStatus.Disconnected:
           break;
    }
 };

await client.ConnectAsync().ConfigureAwait(false);

UI Status

Get the current UI status (room temperature and more)

INefitEasyClient client = new NefitEasyClient(new NefitEasyCredentials {
  SerialNumber = "",
  AccessKey = "",
  Password = ""
});
    
await client.ConnectAsync().ConfigureAwait(false);
    
if (client.ConnectionStatus == NefitConnectionStatus.Connected)
{
   UiStatus status = await client.GetUiStatusAsync().ConfigureAwait(false);
   double temperature = status.InHouseTemperature;
}

Set Room Temperature

Set a room temperature between 5 and 30 degrees Celsius

INefitEasyClient client = new NefitEasyClient(new NefitEasyCredentials {
  SerialNumber = "",
  AccessKey = "",
  Password = ""
});
    
await client.ConnectAsync();
    
if (client.ConnectionStatus == NefitConnectionStatus.Connected)
{
  bool succeeded = await client.SetTemperatureAsync(24d).ConfigureAwait(false);
}

Using in dotnet core project

In StartUp.cs

services.AddNefitEasy(options => {
  IsSingletonClient = true|false,
  AutoConnect = true|false
  Credentials = new NefitEasyCredentials {
    SerialNumber = "",
    AccessKey = "",
    Password = ""
  }  
});

Usage in a controller

public HomeController(INefitEasyClient client)
{
   UiStatus status = await client.GetUiStatusAsync().ConfigureAwait(false);
   double temperature = status.InHouseTemperature
}
