fritzconnection documentation

fritzconnection is a Python library to communicate with the AVM Fritz!Box by the TR-064 protocol, the AHA-HTTP-Interface and also provides call-monitoring. This allows to read status-information from the router, read and change configuration settings and state, interact with smart-home-devices and monitor realtime phone calls.


The available features are depending on the Fritz!Box model and the according system software. Using fritzconnection is as easy as:

from fritzconnection import FritzConnection

fc = FritzConnection(address="", user="user", password="pw")
print(fc)  # print router model information

# tr-064 interface: reconnect for a new ip
fc.call_action("WANIPConn1", "ForceTermination")
fc.reconnect()  # do the same with a shortcut

# http interface: get history data from a device with given 'ain'
fc.call_http("getbasicdevicestats", "12345 7891011")

FritzConnection provides two basic commands to communicate with the router APIs: call_action() for the TR-064-Interface and call_http() for the (AHA)-HTTP-Interface. Both APIs can be used on the same FritzConnection instance side by side. With the call_action() and call_http() methods every service/action-combination and commands documented by the AVM support-page (Apps/TR-064, HTTP) can get executed.

  • call_action() expects a TR-064 service- and an action-name (and optional arguments). In general FritzConnection can execute every service and action provided by the (model-specific) API as documented by AVM. For i.e. this can be network settings, status informations, access to home automation devices and much more. The call_action() method returns the response from the router as a dictionary with the values already converted to the matching Python datatypes.
  • call_http() expects a command for the http-interface like “getbasicdevicestats” and, depending on the command, additional arguments like a device “ain” (identifier). A call to the method returns a dictionary with the content-type, the encoding and the response data of the http-response. The content-type of the response-data is typical “text/plain” or “text/xml” and may need further processing.

The fritzconnection-package comes with a library to make some common tasks easier and can also serve as example code. For a detailed overview refer to Getting Started and the documentation of the library.
