hello, i am using the npm function node to use a function called @network-utils/arp-lookup this function should have a couple of options to get an ip from the corresponding mac address or a mac address from the corresponding ip address isMAC(working true/false is returned) isIP(working true/false…

nice, care to share your flow. changed my flow to make it more simple. indeed only downfall is that arp is slow in responding so i would like to use nmap as well

Sure, here is the flow. Actually 2 flows. One that presents an API url that is called by the script that runs the nmap local scan so that it updates things when the scan finishes. It reads the XML file and combines it into the existing network variable. I initially created that from a spreadsheet t…

wow, very complete. will hve to see if i can implement it. i currently have a script running on my asus router for use as present detection. i think i only need the scipt and the node-red flow to make this work(do not use ui builder but have info in function nodes in my flow.

It is complex only because I wanted to use the resulting variable as my master list instead of the old spreadsheet. If all you want to do is to merge each nmap run into your existing data then you only need: [image] And the script. [image] GravityRZ: i currently have a script running on my as…

OK, that's interesting. What's more, you reminded me that there is a Ubiquiti Unifi API node! That will give me much better data on WiFi attached devices. It will probably give me better presence detection too. I'll try it out.

Oops. Change that to be the IP/MAC of the device from which you are running nmap. :slight_smile:

ok, will try it out.

regarding the presence detection. you are right about the power saving but somehow it works great on my router. maybee because i look for a macaddress present. the router behaves different that let's say nmap or arp . as far as i can tell it works even when any iphone goes to sleep

i use this command to scan for macaddresses

wl -i eth1 assoclist;wl -i eth2 assoclist
