Guest Wifi and Access point control

Hi All

I wanted to share a project with you all that I have been working on - its totally overkill for a home network, but I think it’s pretty cool

I wanted to keep my guests seperate from my core devices on my LAN for multiple reasons. I have a sort of theory around devices I trust and devices I don’t, I feel like isolating your guests on their own LAN is a good practice. (I won’t go into how to install LEDE or setup a Guest WIFI in this post - I’ll just share my Home Assistant integration.

The Guest Wifi only has internet access. I don’t want it to be active all of the time and want the password to refresh on a periodic basis, utilizing Home Assistant I want guests or the significant other to enable or disable the guest wifi and display the current guess wifi password.

To achieve this I had to install LEDE on my router, create a few bash scripts to disable/enable the Wifi, check its status and regenerate a password.

I created some command line switches to run the scripts from Home Assistant and interface looks like this


Running LEDE on my router and doing a SSH keyless password exchange between the Home Assistant server and my router(saves exposing my server password to my HA config or the scripts) - I can SSH to my router and run UCI commands to perform set activities, like disabling the wifi or setting the guest password.

Guest Wifi Current Password


command="ssh [email protected] \"uci show wireless.Guest.key | cut -d\' -f 2\""

result=`eval ${command}`
echo $result;


  - platform: command_line
    command: '/home/user/scripts/wifi/guestPassword'
    name: GuestWifiPassword

Generate new Guest Wifi Password
Running via CRONTAB every Wednesday

newpassword=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 8 | head -n 1)

command="ssh [email protected] \"uci set wireless.Guest.key=${newpassword}; uci commit wireless; wifi\""

result=`eval ${command}`
echo $result;

HA Switches

To check status of Wifi and enable or disable

    command_on: '/home/user/scripts/wifi/enableWifi 0 Guest'
    command_off: '/home/user/scripts/wifi/enableWifi 1 Guest'
    command_state: '/home/user/scripts/wifi/Wifi2gStatus Guest'
    value_template: '{{ value == "on" }}'
    friendly_name: Guest Wifi

Script for Guest Wifi Status

Find the current status of the guest wifi



command="ssh root@${RouterToCheck} \"uci show wireless | grep wireless.${wifiToCheck}.disabled |cut -d\' -f 2\""

result=`eval ${command}`

if [ -z "$result" ]; then
               echo on
               echo off

Enable or disable Guest Wifi

Single script to manage enablement or disablement of the Wifi


if [ "$stateToSet" -eq "0" ]; then
               command="ssh root@${RouterToCheck} \"uci delete wireless.${networktochange}.disabled; uci commit wireless; wifi\""
               command="ssh root@${RouterToCheck} \"uci set wireless.${networktochange}.disabled=${stateToSet}; uci commit wireless; wifi\""

result=`eval ${command}`
sleep 30

Its been working very well for the last few months and has a high WAF factor while keeping my network a little more secure and not having to share my wifi password with everyone.

Next steps might be automatic disablement when the Guest Wifi hasn’t had any use for a set time - I also bet there is a whole host of other things you can do on your lan using LEDE and Home Assistant.

You’ll also notice I have multiple routers with multiple WiFi Access points to help with full home wifi coverage.

Let me know what you think and any suggestions you might have.


Very cool. I’ve always wanted to do this but quite often guests want the ability to airplay from iPhones to my Apple TV. Is there a way of allowing internet access only + route to Apple tv IP only for airplay.

(Quick hack) I think you can enable bluetooth on Apple TV - when they come over they can pair with it via the code on the TV and stream

  • Just re-read your post - you said Apple TV IP only - ill do some reading, I think there will need to be some broadcasting of the Bonjour service, there must be a guide out there

Any update on this?

Oooh. This looks really nice. It’s been a long time since anyone has posted here. Any updates? Still working?
