ioBroker fritzbox Adapter
This adapter uses Sentry libraries to automatically report exceptions and code errors to the developers. For more details and for information how to disable the error reporting see Sentry-Plugin Documentation! Sentry reporting is used starting with js-controller 3.0.
AVM Fritz!Box®
The Fritz!Box (own spelling of the manufacturer AVM) is one of the most widely used routers on the market.
There are now models for all common types of internet connection: DSL, cable, mobile and fiber access.
Adapter Fritzbox
The adapter establishes a connection between the Fritz!Box (short: FB) and ioBroker and provides data and lists of calls.
Prerequisites before installation
The data exchange takes place via the call monitor integrated in the FB. To activate it, dial the following number from a connected telephone:
#96*5*- switch call monitor on#96*4*- switch call monitor off
Install
Choose Adapter "fritzbox" in ioBroker Admin
Configuration
Settings
Here you only have to activate which data should be transmitted and in which form. According to the developers some data fields are unnecessary (see the graphic and the thread in the forum); this adapter does not receive any further updates, as it can be replaced by the more powerful "TR-064" adapter.

Further information in the forum in this thread.
Autosetup
see Settings
Instance
Under Instances of the ioBroker you find the installed instance of the adapter. On the left it is visualized in a traffic light system whether the adapter is activated and connected.

If you place the mouse pointer on a symbol, you get detailed information.
Objects of the adapter
In the objects area all values, lists and information transmitted by the FB to the adapter are displayed in a tree structure (see settings).
Directly in the instance folder fritzbox.x you find the data point message with date, time and type of the last action.

The respective channels and the data points created therein are briefly described below.
Channel callmonitor
The data points show the calls in real time.
| data point | description |
|---|---|
| all | display of date, time and phone number; incoming and outgoing |
| call | display of date, time and phone number; outgoing |
| connect | display of date, time and phone number of an existing connection |
| ring | display of date, time and phone number of incoming calls |
Channel calls
Within this channel 2 more channels and some data points are created:

| data point | description |
|---|---|
| callLastNumber | last dialed phone number |
| connectNumber | last currently connected call |
| connectNumbers | all currently connected calls |
| missedCount | counter of missed calls |
| missedDateReset | date of the last counter reset |
| ring | signal for an incoming call |
| ringActualNumber | phone number of a currently incoming call |
| ringActualNumbers | phone numbers of all currently incoming calls |
| ringLastMissedNumber | phone number of the last missed call |
| ringLastNumber | phone number of the last incoming call |
counterActualCalls
Here the values of the various counters of current calls are listed in real time:
| data point | description |
|---|---|
| allActiveCount | number of all active calls (connected, incoming) |
| callCount | number of outgoing calls |
| connectCount | number of existing connections |
| ringCount | number of currently incoming calls |
telLinks
The data points listed below are formatted as a link, so that the corresponding number can be dialed via the link (e.g. via a widget in VIS):
| data point | description |
|---|---|
| callLastNumberTel | redial, last dialed phone number |
| ringLastMissedNumberTel | last missed call |
| ringLastNumberTel | last incoming call |
Channel cdr
These data points provide information in formatted form (see settings).
| data point | description |
|---|---|
| html | last call |
| json | |
| missedHTML | last missed call |
| missedJSON | |
| txt | last call |
Channel history
These data points provide tables in formatted form. Which information is transmitted can be defined in the settings.
| data point | description |
|---|---|
| allTableHTML | |
| allTableJSON | all calls |
| allTableTxt | |
| missedTableHTML | missed calls |
| missedTableJSON |
Channel system
| data point | description |
|---|---|
| deltaTime | delta time between ioBroker system time and Fritzbox in sec |
| deltaTimeOK | test result (true/false) |
FAQ
Q: There is the Fritzbox and the TR-064 adapter, which also accesses the FB call monitor. What are the differences, do both adapters have to be installed?
A: The Fritzbox adapter comes from the initial phase and made only those of the possible information of the router available which concerned the calls.
TR-064 can be considered a further development, as this adapter offers much more extensive information, e.g. about the devices registered at the FB.
In principle it is sufficient if one of the two adapters is installed. However, since many long-standing users use the FB adapter and have built their visualization on it, it remains available but is no longer being developed.
Newcomers are recommended to install the TR-064 adapter.

- a red bar showing the caller's phone number during an active incoming call
- a graphical timeline showing the number of calls by type: ringing, call setup, and connected
- counter for missed calls with a reset button
- list of missed calls
- list of all calls with color coding (connected/not connected) and direction
- counters for: currently ringing calls, outgoing call setups, connected calls, total calls/call attempts
- an info field that turns yellow when the FRITZ!Box time deviates too much from the ioBroker system time

FRITZ!Box Live Call Monitor Widget
Shows all active calls, incoming calls (ringing), and outgoing call setups. The duration is displayed for active calls and incoming calls (updated every second).

FRITZ!Box Call List Widget using the "basic - HTML Widget"
The column contents and their headers can be freely chosen in the widget. This also allows headings in other languages.

FRITZ!Box Widgets: Information About Current and Past Callers
The info widgets are examples of individual data points generated by the FRITZ!Box adapter.
There is one data point with the phone number as output by the FRITZ!Box (a), and one data point with the phone number converted to a dialable link (b) (e.g. the number 020147114711 is displayed and linked with tel:+4920147114711). The tel-links are useful, for example, on VIS interfaces on smartphones, to return a missed call with a single tap.
Example widgets:
- (1) last caller
- (2) current caller (shown for the duration of ringing)
- (3) last caller who was missed (not answered)
- (4) redial: last dialed a phone number
