Hi all - just wanted to update. I was re-reading the forum, and saw that someone had erroneously typed “device” instead of “devices” in the config file. That was my error too!

Re: MMM-NetworkScanner No Devices

Hi - I am a newbie. Had to redo MM and all Modules, including NetworkScanner. I did the install procedures as laid out.

One thing I couldn’t do was updating the vendor databases using the:
cd /usr/share/arp-scan
sudo get-iab -v -u http://standards-oui.ieee.org/iab/iab.txt
sudo get-oui -v -u http://standards-oui.ieee.org/oui/oui.txt

When I try those commands, it says “unknown option u” and it also gives another default URL. When I drop the -u and http, it says it can’t get both the OUI and IAB data.

The module works, but shows no devices in MM. I ran the arps2mm.sh script manually and it does show a list of devices but none appear in MM. the arps2mm script also tells me it can’t find the iab.txt and oui.txt file which is not surprising since it’s not there.

So how do I get the said text files, and hopefully this solves my issues? Thanks in advance.

Looks great. Are you using home-assistant for your Smart Home? And is it also on the same raspberry pi?

Thank you. I actually did a new complete install from scratch and got MM to work!

@wippo Hi - can you be more detailed when you say “you have to start the graphic desktop before execution”? I am pretty new to this and have no idea what you mean. I have the exact same errors on the same set up you have. Thank you.
