If you have any issues or ideas for improvement you can contact me in the [CMK forum](https://forum.checkmk.com/) by sending me a direct
message to `@thl-cmk` (this is the prefered way) or send me an email to _thl-cmk[at]outlook[dot]com_.
If you have any issues at least let me know what CMK version/edition you are running, what Fritzbox (model/version) you are using.
For some fixes/improvements I migth need the _agent output_ from the device in question.
For example, first get the actual command line from CMK:
```
OMD[build]:~$ cmk -D ares | grep Program
Program: /omd/sites/build/share/check_mk/agents/special/agent_fritzbox 192.168.10.254
Program: /omd/sites/build/local/share/check_mk/agents/special/agent_fritzbox_smarthome --pwstore=3@0@ares 192.168.10.254 --password '********************' --user checkmk --port 8443 --ignore_ssl --no-piggyback
```
Then run the agnt with exact the same options and add `--debug`
```
OMD[build]:~$ /omd/sites/build/local/share/check_mk/agents/special/agent_fritzbox_smarthome --pwstore=3@0@ares 192.168.10.254 --password '********************' --user checkmk --port 8443 --ignore_ssl --no-piggyback --debug
Raw XML:
b'1Temp012050413935390100170397360035\n'

```
The first part is the raw XML output from your FritzBox. The second part is the parsed agent output.
