Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: BSB002
What that covers: Hue Bridge v2; the hub every Zigbee accessory reports through, and the only component in a Hue system with its own network connection.
Not applicable to this hardware: This Hue Bridge v2 does not have the hardware for: has power or battery problems; video is blurry, dark, frozen or delayed; misses motion or records too many events. Those symptoms have no page here for this model rather than a page that guesses.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Capacity: Philips states the Bridge supports up to 50 lights and 12 accessories. Those are two separate limits, and the accessory limit is the lower and the one people reach first — a switch or sensor that will not pair on a large system is worth checking against the 12-accessory figure before anything else.
Network: Connects to the router by Ethernet cable, not Wi-Fi. That is the single most useful fact about this device for troubleshooting: Wi-Fi problems cannot affect the Bridge's own connection, and a Wi-Fi fix will never help it. What can affect it is the cable, the router port and the router's client list.
Radio to accessories: Zigbee to every light and accessory. Accessories have no independent path to anything — they reach the Bridge over Zigbee and nothing else — so a Bridge fault presents as every light and switch failing at once, and no accessory-level check means anything until the Bridge is confirmed working.
Power: A supplied mains adapter, 120 V in the US, with standby power consumption stated as 0.1 W. There is no battery, so the Bridge stops with the power and returns with it, and everything commissioned to it stops too.
Mesh behaviour: Mains-powered Zigbee devices — the lights — repeat the mesh. Battery accessories such as dimmer switches and motion sensors do not. That is why adding another battery accessory never improves range, and adding a mains-powered light often does.
Philips Hue's own specification: Philips publishes the Bridge's specification at philips-hue.com/en-us/p/hue-bridge/046677458478, and its support section for the system at philips-hue.com/en-us/support/product/philips-hue-system/100005.
Power path: Mains adapter into a standard outlet. Switched outlets and outlets on a circuit that trips are the two failure modes that present as device faults. Use the supplied adapter — third-party adapters that supply the right voltage at the wrong current are a common cause of intermittent restarts.
Radio: Zigbee mesh through a bridge. The accessory has no independent internet path, so a bridge fault presents as every accessory failing at once. Mains-powered Zigbee devices repeat the mesh; battery ones do not, which is why adding a battery accessory never improves range.
Radio: Wired Ethernet available. A wired path removes signal strength, band steering and Wi-Fi credentials from the investigation entirely, and is worth using during diagnosis even if the device will end up wireless.

Exact questions

Questions that only have an answer for the Hue Bridge v2

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Does the Hue Bridge connect over Wi-Fi?+

No — it connects to your router by Ethernet cable. This is the most useful thing to know when troubleshooting it: a Wi-Fi problem cannot affect the Bridge's own connection, and no amount of Wi-Fi work will help. Check the cable, the router port and the router's client list instead.

How many devices can the Hue Bridge handle?+

Philips states up to 50 lights and 12 accessories. Those are separate limits, and the 12-accessory limit is the lower one — so a switch or sensor that refuses to pair on a large system is worth counting against that figure before assuming the accessory is faulty.

All my Hue lights stopped working at once.+

Check the Bridge first. Every light and accessory reaches it over Zigbee and has no independent path to anything else, so a Bridge fault takes the whole system out simultaneously. It also has no battery, so a power cut does the same thing.

Will adding another dimmer switch improve my Hue range?+

No. Mains-powered Zigbee devices — the lights — repeat the mesh; battery accessories such as switches and sensors do not. Adding a battery accessory adds a leaf to the network, not a relay. Adding a mains-powered light in the gap is what extends range.

How much power does the Bridge use?+

Philips states standby power consumption of 0.1 W, from a supplied mains adapter (120 V in the US). Its own consumption is negligible; what matters is that it has no battery, so anything depending on it stops during a power cut.
