Philips is getting rid of the need for a specialized and proprietary hub in the latest version of its Hue smart bulbs, indicating that the days of conflicting and confusing smart home products may finally be coming to an end.

Rather than require the bulbs – which can be programmed to turn on and change their brightness and color as needed – communicate through a separate $60 hub, the new kit from Philips' light division, known as Signify, will use standard Bluetooth instead.
