WiFiXpert Compatibility Score — Philips Hue Play HDMI Sync Box
Unlike the bulbs, this one is a proper Wi-Fi device — and it needs to reach the bridge on the same network.
Usually fine, with a couple of catches
Eight checks, same for every device. The eight numbers below add up to 79.
The eight checks
| What we check | Rating | Points |
|---|---|---|
Works on 2.4 GHz Joins the long-range band without trouble. | Excellent | 14/14 |
Works on 5 GHz Uses the faster band, which suits it sitting beside the TV. | Supported | 12/14 |
Modern Wi-Fi security Fine with current router security. | Good | 11/12 |
Happy on mesh Wi-Fi Fixed by the TV, so it holds one box steadily. | Good | 13/16 |
Works on a guest network Cannot reach the bridge from a guest network. | Poor | 2/8 |
Survives a plug-in extender Sync box and bridge on two different network names will not pair. | Issues possible | 6/8 |
Doesn't depend on chatty discovery Finds the bridge and the app using local discovery messages. | Moderate dependency | 12/16 |
Easy to fix when it goes wrong Re-pairing means reaching behind the TV for the button. | Medium | 9/12 |
| WiFiXpert Compatibility Score | 79/100 | |
What usually goes wrong
The app finds the box but it never links to the bridge, or the lights lag behind the picture.
Free things to try, in this order
- 1
Put the sync box, the bridge and your phone on the same Wi-Fi name.
- 2
Wire the sync box to a mesh box's spare port if there is one behind the TV.
- 3
Turn off client isolation so the box and the bridge can see each other.
Before you buy anything
A cable behind the TV, not new lights.
Answers about this gadget
What it needs from your network
Dual-band Wi-Fi device — unlike the bulbs — that must reach the Hue bridge on the same network.
- Bands it uses
- Bridge: Ethernet preferred. Direct Wi-Fi bulbs: 2.4 GHz only.
- How it's found
- The app finds the bridge with local discovery. Bulbs behind a bridge never touch your Wi-Fi at all.
- 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 cable from a mesh box behind the TV — Removes both the pairing and the lag problem.
