Fixing Unadoptable Unifi Devices

I wrote an article about this before that utilizes Robo3T. I figured I should also have a version for those of you who utilize SSH and Command Line.

DISCLAIMER: I am not responsible if you break anything. If you need help let me know before you create a big mess!

EDIT: I wrote a Python Script that can handle all of this for you just enter in your MAC address. Grab it here: https://github.com/avansledright/unifideletedevice

SSH into your Unifi Controller utilizing whatever means you typically use.

Connect to MongoDB by issuing the command:
mongo --port 27117

If you are utilizing a different port then change the port flag.

Once connected select the Unifi Database:

use ace

Then you can utilize the following queries to preform actions:

Find device:
db.device.find({ 'mac' : 'XX:XX:XX:XX:XX:XX' })
Remove device:
db.device.remove({ 'mac' : 'XX:XX:XX:XX:XX:XX' })

Should you want to find what site a device is registered to you can utilize the “Find Device” query from above. In the JSON output locate the Site ID. Then utilize the query below and replace the X’s with your found site ID. The result should be a nice JSON output with the name of the site.

Find site query:
db.site.find(ObjectId('XXXXXX'))
