On year ago i wrote about adding a FritzBox to my monitoring with grafana and influxdb: https://dietrichschroff.blogspot.com/2021/11/fritzbox-monitoring-with-grafana-influx.html
This was done with collectd.
As i wrote in https://dietrichschroff.blogspot.com/2022/09/ubuntu-raspberry-pi-upgrade-to-2204.html i upgraded my raspberry to 22.04 and along with many minor problems, collectd was gone. (and i think it will not be added anymore.)
All other monitorings use telegraf to get the data.
And there is a solution, which provides that:
You can follow the steps on this page. If you get no data - here is the commandline which you should use to test the connection:
python3 ./TelegrafFritzBox/telegrafFritzBox.py -p xxxxxx -i 192.168.178.1 -u fritz8490
And this should be the command, which you use in
/etc/telegraf/telegraf.d$ cat telegrafFritzBox.conf
The reward is really a very nice dashboard:
