UniFi Switch 24 (Gen1)

Quick verdict

The UniFi Switch 24 (Gen1) is a managed 24-port gigabit switch (non-PoE) with two 1G SFP uplinks. In Home Assistant this surfaces through the local UniFi Network integration as a monitored network device plus client device_tracker entities for presence detection. It is reliable, fully local monitoring, but note HA treats it as a network device to watch, not a controllable smart-home device.

Compatibility snapshot

Why it stands out

• 24 gigabit RJ45 ports plus 2x 1G SFP uplinks; non-PoE, low power draw
• Straightforward layer-2 managed switch with VLANs and per-port stats in UniFi Network
• Surfaces in Home Assistant via the local UniFi Network integration as a monitored device with PoE/port and client data

Reasons to hesitate

• Monitor-only in Home Assistant - you can watch port/PoE state and clients, but not switch ports on and off from HA's UI
• Needs a UniFi OS controller (UDM/Cloud Key) for the HA integration to read it
• Discontinued by Ubiquiti; still fully supported in current UniFi Network, but buy used/refurbished

Best for

• UniFi households wanting wired clients tracked locally in Home Assistant
• Anyone who needs PoE for cameras, APs, or sensors with local HA monitoring

Avoid if

• You do not run a UniFi controller
• You expect to control individual ports from Home Assistant's dashboard

Privacy and local-control notes

The UniFi Network integration talks to your local UniFi OS controller over the LAN using a local-only account (Ubiquiti SSO cloud login is not supported). Device and client data, including presence detection, stays on your network.

Home Assistant support: supported · integration path: UniFi Network (local polling of the UniFi OS controller; local user required).

Buying reality check

Price notes: Model US-24 (Gen1, non-PoE). Older generation, still supported in UniFi Network; check used/refurbished or the current USW-24 equivalent.
