Philips Hue Bridge — smart-home gadget keeps going offline
Why does my Philips Hue Bridge smart device keeps going offline?
The short answer
The app says "bridge not found" even though the lights still work from the wall switch. On the WiFiXpert Compatibility Index the Philips Hue Bridge scores 90/100, and its weakest check is "Works on a guest network" — which is exactly where this problem comes from. Your phone must be on the same normal network as the bridge to control it locally.
We publish what breaks with each router and mesh system, and the setting that fixes it.
