You can set up routines for Philips Hue lamps without a Hue Bridge by using the Philips Hue Bluetooth app. This app allows you to control up to 10 lights and perform simple control functions such as dimming or colour changes. However, advanced functions such as automatic switching on at certain times are limited without a bridge or other centralised control. However, you can use IFTTT to create such automations by creating applets that control the lights based on specific events.
