You can iterate through the list. I’m not best with Jinja, but I’m sure it can be done.
I modified some other array responses and found a solution. Posting below for anyone else that needs to find a specific MAC or Device
| map(attribute='mac') | select('search', 'xx:xx:xx:xx:xx:xx')
| list | count }}’’’
If that results in “1”, it’s active, otherwise it’s inactive.

Thanks! that was what I was looking for
How/where do I change the scan interval from 15 minute?
Thanks.
How do I change row color of flex table when the device name is ‘Unknown Device’
I tried this:
css:
tbody tr+: “user-select: text”
table+: “border: 0;”
thead th: “background-color: #aaa”
tbody tr:
- background-color: |
{% set n = x.name %}
{% if (n == ‘Unknown Device’) %} red
{endif}
I ended up adding a conditional statement to the modify property.
type: custom:flex-table-card
title: Clients
grid_options:
columns: 24
entities:
include: sensor.network_scanner
sort_by: x.ip+
columns:
- name: IP Address
data: devices
modify: x.ip
- name: MAC Address
data: devices
modify: x.mac
- name: Name
data: devices
modify: |-
if (x.name == 'Unknown Device'){
'<div style="background-color:lightcoral">' + x.name + '</div';}
else {
x.name
}
- name: Description
data: devices
modify: |-
if (x.type == 'Unknown Device'){
'<div style="background-color:lightcoral">' + x.type + '</div';}
else {
x.type
}
- name: Vendor
data: devices
modify: x.vendor
css:
table+: "border: 0;"
thead th: "background-color: #aaa"
tbody tr+: "user-select: text"
tbody tr:hover: "background-color: gold!important;"
Any idea how to add the count of devices as the title for the flex table card configuration?
I haven’t used flex table card.
This is what I have as a collapsable card with total devices at the top, it’s not the prettiest, but with a little work

This is odd, to me it is. I used the Flex Table card and the coding that is provided here. On my PC screen the table is perfect. From my Cell phone running the HA app I get a "Custom element doesn’t exist: flex-table-card. Why would this happen??
Thanks
Hello , is there a way to increase the number of entries to more than 25 in the flow dialog box ?
after a couple of days it started working on my Pixel Not sure why but it is working now
You can change the number in Developer Tools under States.
To expand upon this card, I modified it a little bit. I did see that TD has a margin left/right so text in div, especially in multiline isn’t centered and there’s a small gap. I changed the div into a span and used the selector on the TD when there’s a span.warning-cell present inside of it.
The colors are also dynamic now so it’ll follow your theme nicely:
type: custom:flex-table-card
title: Clients
grid_options:
columns: 48
entities:
include: sensor.network_scanner
sort_by: x.ip+
columns:
- name: IP Address
data: devices
modify: x.ip
- name: MAC Address
data: devices
modify: x.mac
- name: Name
data: devices
modify: |-
if (x.name == 'Unknown Device'){
'<span class="warning-cell">' + x.name + '</span>'}
else {
x.name
}
- name: Description
data: devices
modify: |-
if (x.type == 'Unknown Device'){
'<span class="warning-cell">' + x.type + '</span>'}
else {
x.type
}
- name: Vendor
data: devices
modify: x.vendor
css:
tbody tr:hover: "background-color: color-mix(in srgb, var(--primary-color) 80%, transparent);"
tbody td:has(span.warning-cell): "background-color: var(--warning-color);"
tbody tr+: "user-select: text"

Very nice! I cannot wait to try this. I had to restore my HAOS and the network scanner has not properly initialized since, so once I get through that, I will try this.
After restoring my HAOS I was able to get this change in the card. It’s awesome! Any idea how to add device count to the same card?
Hello, I have two questions:
I have set up the integration and it scans my devices, but I cant get to the menu in the wizard where I can add aliases for the mac’s. can I get there somehow withour having to reset my integration?
Is it possible to get notifications when new unknown devices connect on lan with this addon somehow?
I found this thread that seems working:
Ok, here's what's happening. If you first set up the integration through the UI and then customized it through configuration.yaml, you'll need to delete the original configuration from the UI.
Then you'll need to click "Add Entry" and it will populate with the full list of configuration.yaml customizations.
I believe the issue is this integration doesn't generate unique IDs for its platform. So you'll get an error in the log:
"Platform network_scanner does not generate unique IDs. ID network_scanner_xxx.xxx.xxx.xxx/24 already exists - ignoring sensor.network_scanner"
