ntopng , fritzbox (fritzdump.sh) and geolocation
The latest browsers have removed the Geolocation API from unsecured Origins. If you still want to use Geo-API tools with fritzdump.sh ntopng needs to run secure, based on ssl (TLS).
ntopng has written a nice howto to use let’s encrypt-based certs.
But what needs to be adjusted on the firtzdump.sh script ?
if you want to run only ntopng with TLS on port 3001 and disable http the original line:
wget --no-check-certificate -qO- $FRITZIP/cgi-bin/capture_notimeout?ifaceorminor=$IFACE\&snaplen=\&capture=Start\&sid=$SID | ntopng -i -
should be adjusted to:
wget --no-check-certificate -qO- $FRITZIP/cgi-bin/capture_notimeout?ifaceorminor=$IFACE\&snaplen=\&capture=Start\&sid=$SID | ntopng --https-port=3001 --http-port=0 -i -
Done 🙂
How do I debug Tradfri on Openhab ?
open the openhab-cli:
root@rpi6:/home/pi# openhab-cli console
Logging in as openhab

Milestone Build
Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown openHAB.
Find the packacke-namespace of the tradfri bundle:
openhab> bundle:list -s|grep trad 226 │ Active │ 80 │ 2.5.0.M4 │ org.openhab.binding.tradfri
get the current debug-level:
openhab> log:get org.openhab.binding.tradfri INFO
change the debug-level if needed:
openhab> log:set ERROR org.openhab.binding.tradfri openhab> log:set DEBUG org.openhab.binding.tradfri openhab> log:set INFO org.openhab.binding.tradfri
