API

Tip for decoding: On this Website (German) you can read about the coding system. If you click on a medium there, you will see what the digits of the code stand for in each case.

Authentication

Basic Auth

smart-me API uses "Basic Authentication". Every call to the API must include the Authentication. HTTP Basic Authentication allows credentials (such as a username and password or an API token) to be transferred in HTTP headers. The secret is encoded using Base64.

OAuth 2.0

smart-me supports the authorization framework OAuth 2.0. External applications can apply for access to an account without having to know the login credentials.

OAuth information

smart-me supports the authorisation framework OAuth 2.0. External applications can request access to an account without knowing the credentials.

Setting up OAuth in the smart-me portal

The prerequisite for using oAuth is an account with the professional licence model. If you do not yet have an account with the professional licence model, you must purchase 1 licence.

Login to the smart-me portal
Select user at the top right
Settings
API & Access Change

Add oAuth applications

Trusted (Limited to 3 Client ID)
- Client ID and Client secret will be created
Public (Limited to 3 Client ID)
- Client ID is created
Device (Limited to 50 Client ID)
- Client ID and Client secret will be created

Required information

Name
Redirect Urls
Required permissions

Grants & Endpoints

The implementation of OAuth is not described on our wiki. For example, you can find the necessary information to implement oAuth on this page: https://oauth.net/2/

Supported Grants (Flows) for oAuth Confidential and Public Applications:

- Authorization Code

- Authorization Code with PKCE

- Implicit Flow (deprecated)

- Device Code

- Refresh Token

Supported Grants (Flows) for oAuth Device (Client Credentials) Applications:

- Client Credentials

smart-me Endpoints

- Authorization: /api/oauth/authorize/

- Token: /api/oauth/token/

- Device Code: /api/oauth/device

Realtime (Webhook) API

The smart-me Realtime (Webhooks) API allows you to subscribe to new data of a device. You can subscribe to a single device or to all devices of a user. When a device sends new data to the cloud, a webhook sends this data as a POST request to a reconfigured URL. More Information [1]

API Client Library for .Net

To integrate smart-me API functionality into your .Net application you can use this library. It makes HTTP requests to the smart-me REST API. All HTTP request and response bodies are mapped to .Net classes.

Realtime (Webhook) API Example

The smart-me Realtime API sends the data serialized with google protobuffer

Proto File

package RealtimeApi.Containers;

import "bcl.proto"; // schema for protobuf-net's handling of core .NET types

message DeviceData {

required bcl.Guid DeviceId = 1;

required bcl.DateTime DateTime = 2;

repeated DeviceValue DeviceValues = 3;

}

message DeviceDataArray {

repeated DeviceData DeviceDataItems = 1;

}

message DeviceValue {

required bytes Obis = 1;

required double Value = 2;

}

Proto File without BCL

syntax = "proto2";

package com.company;

message TimeSpan {

required sint64 value = 1; // the size of the timespan (in units of the selected scale)

optional TimeSpanScale scale = 2; // the scale of the timespan [default = DAYS]

enum TimeSpanScale {

HOURS = 1;

SECONDS = 3;

MILLISECONDS = 4;

TICKS = 5;

MINMAX = 15; // dubious

}

message DateTime {

optional sint64 value = 1; // the offset (in units of the selected scale) from 1970/01/01

optional TimeSpanScale scale = 2; // the scale of the timespan [default = DAYS]

optional DateTimeKind kind = 3; // the kind of date/time being represented [default = UNSPECIFIED]

enum TimeSpanScale {
