WiFiXpert Compatibility Score — Philips Hue smart bulb (Zigbee)

Name: Philips Hue smart bulb (Zigbee)
Brand: Philips Hue

Not a Wi-Fi device at all — the bulbs talk to the bridge on their own low-power radio, which is why they rarely break.

90out of 100

Plays nicely with almost any Wi-Fi

Eight checks, same for every device. The eight numbers below add up to 90.

The eight checks

What we check	Rating	Points
Works on 2.4 GHz The bulb never joins your Wi-Fi; it relays to the bridge.	Not used	14/14
Works on 5 GHz Same reason.	Not used	14/14
Modern Wi-Fi security Nothing to mismatch with your router's security settings.	Excellent	12/12
Happy on mesh Wi-Fi The bulbs form their own mesh and relay for each other.	Excellent	15/16
Works on a guest network Your phone still has to reach the bridge on the main network to control them.	Poor	3/8
Survives a plug-in extender Wi-Fi extenders make no difference to the bulbs.	Unaffected	8/8
Doesn't depend on chatty discovery Only the app-to-bridge step uses local discovery.	Low dependency	14/16
Easy to fix when it goes wrong A bulb that drops off is usually too far from the nearest Hue light, not a Wi-Fi issue.	Easy	10/12
WiFiXpert Compatibility Score		90/100

What usually goes wrong

One bulb at the end of the garden or in the loft keeps going 'unreachable'.

Free things to try, in this order

1
Add any mains-powered Hue light between the bridge and the far bulb — each one relays for the next.
2
Keep the bridge away from the router itself; the two radios interfere at close range.
3
Don't blame your Wi-Fi: the bulbs never use it.

Before you buy anything

A cheap Hue plug halfway to the far bulb, not new Wi-Fi kit.

Answers about this gadget

Philips Hue smart bulb (Zigbee) — smart-home gadget keeps going offline

What it needs from your network

Zigbee bulb. It never joins your Wi-Fi at all — it relays to the Hue bridge through the other Hue lights.

Bands it uses: Bridge: Ethernet preferred. Direct Wi-Fi bulbs: 2.4 GHz only.
How it's found: None on Wi-Fi. Only the app-to-bridge step touches your network.
Background discovery traffic: Moderate — used to find the bridge.
On a guest network: The app cannot find the bridge from a guest network.
On a separate gadget network: A bridge is a good candidate for an IoT network, as long as your phone can still reach it.

Getting it set up

• Plug the bridge into the router by cable.
• Direct Wi-Fi bulbs must be added one at a time, near the router.
• Stand next to your router while you set it up, then move the gadget to where it lives.
• Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
• If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
• Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.

With mesh Wi-Fi

• A bridge on a mesh box's Ethernet port works fine.
• Dozens of direct Wi-Fi bulbs on one mesh box will fill it up — a bridge is the better answer past about fifteen bulbs.

If it simply won't play nicely

A Hue plug halfway to the far bulb — Each mains-powered Hue device relays for the next one.
