Need to Specify the serial input
Start the serial connection
Print input to log
// Set analog pin variable
const int aPin = A0;
void setup() {
// Start Serial connection
Serial.begin(9600);
}
void loop() {
// Print analog input to Serial Monitor
Serial.println(analogRead(aPin));

Using an O2 Sensor which has the following connections
SSH into the UniFi. Note that the UniFi username and password get updated from the controller. Refer to here to find username and password.
ssh ubnt@192.168.1.20
run the syswrapper.sh script with the restore-default option
syswrapper.sh restore-default
Once the device is reset, log in over ssh and reconfigure.
Note that the username and password will now be ubnt/ubnt
In the newer controller versions, you should be able to go to
Settings -> NETWORK SETTINGS -> Device Authentication
To view the SSH credentials.
Go to Settings -> Site -> DEVICE AUTHENTICATION

Looks like you can use Darling to run MacOS command line applications in Linux.
Helpful commands. Maybe?
Looks like most of the configuration scripts are in /sbin

Not exactly sure if this does work, but seems like it should.
nvram_get SSH_SERVER_REMOTE_ENABLE
Default status
Enable
nvram_set SSH_SERVER_REMOTE_ENABLE 1
After running above command
Commit changes
nvram_get commit
Reboot
reboot
Seems like I am missing a step. Seems to change the password in the nvram, but does not actually change it permanently
Get current password
nvram_get 2860 Password admin
nvram_set Password newpassword

You should be able to copy and paste the following in a backup.sh file and then execute from cron. Should work out of the box, but you can change the backup directory and the teams.sh path if needed/wanted.

Was getting the following error when trying to install MongoDB. Think I was trying to install Mongo following the instructions on their site and then it caused issues with apt.
dpkg: error processing archive /var/cache/apt/archives/mongodb-org-server_4.2.5_amd64.deb (--unpack):
trying to overwrite '/usr/bin/mongod', which is also in package mongodb-server-core 1:3.6.3-0ubuntu1.1
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
Removed the following file
rm /etc/apt/sources.list.d/mongodb-org-4.2.list
and was able to use apt again to install MongoDB. Didn’t end up solving my problem because I technically needed two versions, but at least apt was being nice again. Ended up installing the UniFi controller docker container and can run both on the same server that way.
