If you have experienced that some units on your Wifi network that were previously connected to your fiber or cable router cannot anymore be connected on your internal network – after you installed a set of ORBI mesh units – the reason may be that the ORBI system is not set up in access point mode. If it is set up in router mode, there is an internal firewall that acts in addition to the normal firewall you have in your cable or fiber modem. Log into the orbi unit with orbilogin.com and go to ADVANCED/Advanced/Router/APmode and select AP mode. Reboot the ORBI units and you are all set. All units on your Wifi network are visible (on your internal network). Read more here: https://kb.netgear.com/000061927/What-is-the-difference-between-router-mode-and-AP-mode

Wifi setup for Home Assistant via COMMAND LINE
Power on HA
Have a screen and a keyboard connected
When you see the ha> prompt enter login
Then do this:
nmcli radio

Now scan and list available wifi access:
nmcli device wifi rescan
nmcli device wifi

Connect to wifi:
Use quotes around your ssid and password:
nmcli device wifi connect "YOUR_SSID" password "YOUR_WIFI_PASSWORD"
This will try to connect to your SSID and will generate a network profile for you if successfull.
The output will be similar to"Device 'wlan0' successfully activated with...."
Then check your connections again:
nmcli con show

You should be seeing at least two profiles and both green.
If you are seeing some profiles you’d like to get rid of you can remove them using:
nmcli connection delete CONNECTION_NAME

These may have two separate ip addresses on your network: one for ethernet, one for wifi.
You can check the ip addresses using:
ip addr show
Now connect to http(s)://your_wifi_ip:8123
in your browser.

Securing your node-red editor and dashboard on the Raspberry Pi
If you leave your node-red installation on your rpi running without a password you will be hacked and soon owned by people using your rpi as a bit coin mining device. It is easy to set a password for the editor and for the dashboard!:
Node-red is installed in /home/pi/.node-red (the . dot in front means you will normally not be able to see the directory as the dot means it is hidden. Therefore, set up your file manager to show hidden files. Alternatively, if you are using the terminal you can use ls -a or ls -al in the /home/pi directory to see all that is there).
Edit the settings.js file with
nano settings.js
Uncomment this section in the settings.js file:
adminAuth: {
type: "credentials",
users: [{
username: "admin",
password:"xxxhash key is pasted herexxxx",
permissions: "*"
}]
},
You will need to generate a hash with node-red-admin
and type the hash-pw
command. The hash key you paste above in the field xxxhash key is pasted herexxxx (keep the ” ” signs and dont mess up the [ ] {} , stuff).
You will probably have to install the node-red-admin tools (google how to do that with npm) to be able to use node-red-admin
For the dashboard you do the same procedure but you now un-comment this line
httpNodeAuth: {user:"user",pass:"xxxxdashboard hash key is pasted herexxxx"},
Make sure to keep all commas etc!
If you are uncertain to what directory your rpi reads the settings.js file from, you can start the node-red with node-red-pi and look at the messages in the console. It will report the location and file it uses. Dont edit the wrong settings.js file … there are several installed on your pi it seems
Restart the node red
IMPORTANT! CLEAR THE CACHE of your web browser. If not you will not see the password on the editor and the dashboard, as node-red uses cache quite heavily. See https://support.mozilla.org/en-US/kb/how-clear-firefox-cache for how to clear Firefox cache
