Independent, field-tested configuration guides, explainers, and walkthroughs — written for engineers and serious home-lab operators.
Each guide covers a specific UniFi concept, hardware decision, or configuration task in depth — with real network topologies, working command examples, and honest assessments of where UniFi excels and where it falls short. Guides are updated when Ubiquiti ships firmware changes that alter behaviour.
The UniFi Wi-Fi settings that drop ESP32 and ESP8266 devices, where ESPHome nodes belong on a segmented network, why Ubiquiti's published Auto relay list leaves them out, and the ports and addresses Home Assistant needs.
How UniFi dual-WAN failover and load balancing work — failover triggers, the two modes, and the gotchas every network engineer hits setting up WAN2.
Where Home Assistant belongs on a UniFi IoT VLAN, what breaks across VLANs (mDNS, Cast, Sonos, HomeKit, Matter), and the zone-based policies that fix it.
Compare Home Assistant Cloud, UniFi Teleport and WireGuard, Tailscale and Cloudflare Tunnel for reaching Home Assistant on a UniFi network, CGNAT included.
The UniFi network actions Home Assistant can automate — PoE port cycles, WLAN toggles, rule switches — and the Alarm Manager webhooks that send events back.
A decision guide to nine indoor ceiling-mount UniFi access points — U6 Lite to E7 — by generation, 6 GHz, streams, uplink, PoE class, and coverage.
A decision guide to ten UniFi Protect G6 cameras, from the $179 G6 Instant to the $499 G6 Pro Dome: body, sensor tier, zoom, IR range, PoE class, and storage.
A decision guide to eight UniFi gateways, from the $129 Cloud Gateway Ultra to the $599 Dream Machine Pro Max: IPS throughput, WAN, PoE, Protect and Wi-Fi.
A decision guide to five UniFi switches — Lite 16, Flex 2.5G, Pro 24, Pro Max 24 and Pro HD 24 — across port count, PoE budget, port speed and Layer 3.
What Matter and Thread need from a UniFi network: IPv6 that stays local, multicast nobody has optimized away, and a Thread channel clear of your 2.4 GHz Wi-Fi.
A PoE switch budget is one number that hides class draw, per-port caps and cable loss. How to size PoE across a UniFi switch stack that has room to grow.
Why a Home Assistant Zigbee or Thread radio belongs on PoE in the middle of the house, what UniFi's PoE budget allows, and how to keep the channels apart.
Mounting height, field of view math, and what UniFi Protect IR actually delivers at night — plus the placements that will never produce usable evidence.
Size UniFi Protect storage before you buy: bitrate per resolution, H.264 vs H.265, motion vs continuous recording, RAID overhead, and drive headroom.
What Home Assistant's UniFi Access integration exposes for each door, why doors are buttons rather than locks, where the API token comes from, and the emergency switches to keep out of automations.
How UniFi gateway content filtering, ad blocking, and encrypted DNS work at the DNS layer, where clients bypass them, and how to scope each rule per network.
How to configure UniFi guest networks properly: client isolation, guest control rules, hotspot portal options, and bandwidth profiles that actually hold.
UniFi Threat Management explained: what IDS and IPS signatures catch, how sensitivity levels work, and why IPS lowers your gateway throughput ceiling.
Learn when to move UniFi inter-VLAN routing to a Layer 3 switch, what it changes for zone firewall policies, and which UniFi switches support it.
How to use UniFi switch port profiles, 802.1X, RADIUS and MAC-based fallback to lock down wired ports without breaking printers, cameras and IoT devices.
How Home Assistant's UniFi integration decides home and away, why phones flap (private Wi-Fi addresses, 802.11r, kicks) and how to build presence that holds.
What Home Assistant's UniFi Protect integration exposes, what API-key-only mode drops, which detections need Ubiquiti's Alarm Manager, and the ports it uses.
Which UniFi Protect smart detections reach Home Assistant as events, what the vehicle event carries, and where faces, plate text and line names stop at the public API.
UniFi ships three remote-access paths. Compare Teleport, Site Magic, and manual WireGuard on routing, DNS, gateway support, and when to use each.
Why bonding UniFi ports never doubles one transfer, how LACP hashes flows, and when a 10G SFP+ uplink or 2.5GbE port is the fix for real congestion.
Learn how to design, configure, and troubleshoot VLANs in UniFi Network — from the first broadcast domain to inter-VLAN firewall rules.
Wi-Fi 7 is the default UniFi access point now. What MLO, 320 MHz channels, and the 6 GHz coverage penalty mean for your client fleet, switches, and PoE budget.
Design clean device handoffs across a multi-AP UniFi network with Minimum RSSI, band steering, and 802.11k/v/r fast roaming to stop sticky clients.
How UniFi wireless meshing uplinks an access point over the air, why each hop splits airtime, and when a cable or point-to-point bridge is the better call.
Configure the UniFi zone-based firewall: default zones, custom zones for IoT and cameras, allow and block policy order, and return-traffic handling explained.
Choosing a Home Assistant host from the network side: OS versus container, why every install wants a cable, the address it needs, and the VLAN it belongs on.
