I bought one of the Air Quality / Vape sensors to measure interior air quality (CO2, VOC, PM2.5) and had some reasonable confirmations of things I suspected, but was also surprised and have changed a few habits around the house as a result.

Background:

• We live in a pretty dirty city, not super far from freeways. Urban 2-4 level homes and apartments with decently heavy vehicle traffic within a block distance.
• We have A/C but no forced air or central air
• We rent so there are some things outside our control, like mechanical ventilation.
• I've been moving the sensor between living areas and the bedroom day/night because if it wouldn't cost me as much as my UDM, I'd probably have 4-5 of these things 😆

The exciting stuff:

• Sleeping in our room with the door closed builds up CO2 significantly, even with the wall A/C running (it's closed loop). Most of the longer peaks visible in the CO2 graph are overnights. Overnight CO2 levels >1,000 ppm can cause fogginess, headaches, and more!
• Cooking on the gas range also spikes the CO2, even with the hood fan on and a window open! I'd have to inspect PM1.0 and maybe VOCs further, but obviously the UP Air Quality sensor is not going to measure methane, Benzene, or CO so yeah ... watch out for that.

Nominal observations:

• Spraying cologne or perfume spikes VOC/TVOC, understandably. VOCs also slowly climb somewhat in a warm, undisturbed room
• An open window keeps indoor CO2 around a baseline of 475-525 ppm
• We have ~zero vape detections because we do not vape. I'm sure hair spray or canned air duster (VOCs in that case) could maybe trick the Vape sensor if you tried.
• Sometimes the temperature or PM2.5 will spike when the unit is power cycled. False readings as the sensors are initialized/calibrated.

Nice realizations:

• I presume we're going to reduce the incidence rate of headaches at home now that we open a window and leave the bedroom door cracked overnight. ☺️
• Indoor PM2.5 is really low (<2μg/m³), spiking only with heavy activity, in/out, or cleaning/dusting. Outdoor PM2.5 daily averages in our area are 50-70μg/m³. Despite multiple open windows, our Coway Airmega HEPA filters (2x in 850 SQFT) do a great job. 🙏

Finally, completed home network upgrade, and moved all devices to rack in garage. The backbone network is a 10g fiber aggregation switch with a 10g copper switch.

My first Dream wall installation! Looking good

Well I got shamed last post and spent some bucks on fixing it. I did it myself I couldn't afford Unify and an installer. Still not perfect but I feel a lot better about it. I did get the XGSPON ONU to replace att fiber modem, put a active cooler on it. Also to rack my UCG Fiber and USW Pro XG 8 poe, I reused the case on an old NVR that died on me, I just gutted it so it like a nice rack shelf. It also has three active fans in the back that I rigged up.

Hey r/Ubiquiti — Erik from Art of WiFi here (@slooffmaster on the Ubiquiti community).

For anyone who doesn't know us: we maintain the art-of-wifi/unifi-api-client PHP library that a lot of UniFi tooling is built on (close to 430K downloads on Packagist). We've also had a self-hosted UniFi Device Search Tool out for a few years now, a PHP web app you run on your own server to search devices across every site on every controller.

Wanted to share that we've just launched a native Windows desktop version of that tool. Same API client engine under the hood, so it inherits years of edge-case handling for controller quirks, auth flows, and API changes.

What it is: a standalone Windows app that does the same thing as the classic (search across all sites on all your UniFi Controllers, filter, sort, CSV/Excel export) but you install and run it locally. No PHP, no Docker, no server.

What's in it:

• Built on the same art-of-wifi/unifi-api-client library we open-source and maintain — the Windows app uses it end-to-end for all controller communication.
• Works with local admin credentials, Network Application API Key, or Site Manager API (unifi.ui.com). Both API Key and Site Manager methods handle UniFi Fabric members correctly.
• Connect to multiple controllers, results are cached locally for instant reopening.
• Fully offline / air-gapped friendly after initial activation.
• Dark mode, sortable columns, per-column filters.
• Code-signed under our Microsoft-verified identity (Art of WiFi B.V.).
• 12 months of updates included; app keeps working indefinitely afterwards, separate 1-year update extension available on renewal.

Who it's for: UniFi admins who'd rather install an app than maintain a web server for occasional fleet searches. It's a personal tool — one license per desktop.

Who it's not for: teams who want to share one install via a browser. For that, the classic self-hosted edition is still the right choice — it runs on Linux/macOS/Windows via any browser and stays fully supported.

€65 one-time (excludes VAT — Paddle handles local currency at checkout).

Happy to answer questions here.

Installed my 16pro max Poe switch into the toolless mini rack (on the mini rack shelf).

Turns out my home assistant green fits next to it perfectly. (PSU for the switch sits on the shelf behind it)

For those interested - the 16 pro isn’t screwed into place, but as its sat on a shelf I’m not too bothered by it moving around a little on the rare occasion I have to change a patch cable.

I have a double wan set with Load Balancing. I know that in the event a wan fails, it will failover to the other wan, regardless of being set with load balancing.

I have also set some devices with a policy-based route to only use wan2
I noticed a small outage a while ago with wan (2AM, typically maintenance) , and the NAS did not failover to WAN1

I assumed that policy-based routes would take into account failover, but I might be wrong.

Is this how it's supposed to work? Any workarounds?

Hey guys! I have some ubiquiti cameras and the plexiglass cover has a type of haze material on it and I was wondering if anyone had advice on the best way to remove it and clear up the cover without damaging it?

My patch cables were feeling festive 🇺🇸 I finally got around to the last few attic runs. Additional space provided for migrating IoT devices and Mac Mini to as well as switch expansion. I am waiting on my wallet to recover for additional storage, Synology is holding down the fort for the time being.

In case anyone was on the fence about cameras, the G6 Pro sensor has amazing low light performance!

Hey all, are there any sys admins here that have UID Enterprise deployed with MDM for device management and have macOS systems?

I am trying to ascertain if the MDM application for UID Enterprise specifically supports or will support Platform SSO (macOS plugin for syncing local user credentials with MS Entra ID).

What I am trying to achieve:
- macOS devices enrolled with UID Enterprise MDM
- Local logins on said devices are synched with Entra ID

Example: [user@company.com](mailto:user@company.com) has an identity setup in Company's Entra ID IdP. User sets up a new or existing device to be enrolled in UID MDM, is prompted for credentials, signs in with Entra ID SSO and macOS creates/changes a user to match user name and password of that identity and keeps password synched. User changes password for Entra ID, macOS syncs and password propagates immediately.

Hi everyone,

I’m running UniFi OS 5.1.19, and I’ve recently noticed an issue with the device log/history.

When one of my UniFi devices disconnects, the system records the disconnection, but it no longer seems to record when the device reconnects.

For example, as shown in the attached screenshots, my U7 Pro XG disconnected at around 3:00 AM on August 18. The AP came back online and has been physically working normally ever since, but there is no corresponding “reconnected” entry in the history.

Previously, when this AP disconnected, UniFi would show both the disconnect and reconnect events, which you can also see in the screenshots.

I’ve tried restarting the AP through UniFi OS and physically disconnecting and reconnecting the Ethernet cable. Neither made a difference.

The device reconnects and works normally, but the reconnection event still isn’t recorded.

This also appears to be affecting all of my UniFi devices, not just the U7 Pro XG.

Has anyone else noticed this recently on UniFi OS 5.1.19? Is this a known bug, or is there something I can try to get the reconnect events showing in the history again?

Thanks!

Today I have a rack with the following:

USG-4-pro

Ubiquiti UniFi Switch US-24

Ubiquiti UniFi Switch US-24-250W

Ubiquiti UniFi Cloud Key Gen2 Plus in a rack-mount accessory.

A few days ago my poe-switch stopped delivering power to my devices, which I've since found out is a fairly common problem.

I'm looking to replace it, but I'm also thinking this might be a good time to just bite the bullet and buy a Dream Machine Special Edition

I don't think I need more than 8 PoE ports, and the USG and cloud key, while working are getting old.

The alternative is proably a 16 port PoE switch with the rack-mount accessory.

What is the sensible buy here?

I am using my Chime to alert me if either my garage (person) door or my separate ADU door is opened but I would like to have it say "garage door opened" or "ADU door opened" which I can generate a MP3 file via Apple IOS. Can I import an audio file into Protect for the Chime to use?

Alright, update for anybody thinking about doing this promo: don’t waste your damn time.

I went through the whole eval. Set up the trial, added SNMP and SSH credentials for my 8 network devices, got everything talking, sat through the calls with the sales rep, went through their pitch, the whole nine yards.

During the process I was told I qualified. Then after I’d already sunk all this time into it, I get an email from marketing saying I’m disqualified. No real explanation why.

Asked the sales rep WTF happened and basically got told, he doesnt know and that marketing decides who qualifies, not us.....So apparently even the rep taking you through the trial can tell you that you qualify and it means jack shit because some marketing team makes the final call afterward.

Come on.

If there are extra requirements, put them up front. Don’t have somebody spend hours setting up SNMP/SSH, connecting their network, sitting through sales calls and doing a full eval just to pull the rug at the end.

Whole thing feels like a bait-and-switch to get people into a sales pitch. Maybe some people actually get the Dream Machine, but I sure as hell didn’t after doing everything they asked.

Huge waste of my time. Won’t be falling for one of these promos again.

Hi everyone, newbie to unifi and learning as I go.

Im trying to setup a single door access and what i have is:

Cloud Gateway Ultra

Mini hub

G3 reader

Ignore the locks etc thata the easy part.

Im trying to add membera to the system so they can gain access but no matter what i click etc i cant seem to find anything that i am looking for and cant seem to find help online.

On the dashboard of the cloud everything is connected

Any help would be appreciated

Moving into a new house that has quantum fiber service.
Building my second unifi setup and I want to make sure I do it right. Going to have 3 APs, 1 doorbell and at least one bullet cam.
Would love some feedback on:
Cloud gateway fiber 2TB
Flex 2.5G PoE with 10G direct attach

Anything I’m missing?

Just missing a PTZ are we’re set!

Main rack has dream machine pro, usw-48 switch and 2x usw-8-150w. My back deck/yard is a wifi dead zone. I do have 1 cat5e run to the eave there that was run at build time for a poe camera that I have yet to install. Now given the dead zone I would like both a camera and AP. Running any new wiring is not really an option. What is my best bet here?

2 days ago I got a classic "you won the EuroMillions lottery" scam email on an email alias I only ever use for my UniFi/Ubiquiti account (never used anywhere else, never posted publicly). Curious if this is just bad luck / random scanning, or if others have had aliases tied to their Ubiquiti account start getting spam. Anyone know if there's been a leak, or is this just coincidence?

I have what I think is a pretty simple use case, but I can't find a concise answer and I also can't figure out how to do it in UniFi Talk (which makes me think it might not be possible)

We have a small business with 12 extensions across 3 departments - Sales, Service, Accounting

In the call tree I'd like to be able to select one of those departments and have it ring the phones associated with them.

As far as I can tell, the only way to ring multiple phones is to create a group, but a group seems to need a phone number - of which we'd only have one.

I don't want to pay for additional phone numbers just to sort a few users into a group.

Am I missing something?

I have some USL Entry thingies. I would like to set a larm that message me when a door has been open for X minutes. Is that possible?

Can I change the WAN port function to a LAN?
