Yes, it is possible to switch on two lamps with the Philips Hue motion detector for different lengths of time, although this is not possible directly in the standard Hue app.

- In the standard Hue app, motion detectors can only control entire rooms or scenes, not individual lamps within a room.
- However, to control individual lamps differently, you can use third-party apps such as iConnectHue (for iOS) or All4Hue (for Android). These apps allow you to select individual or multiple lamps from one or more rooms and configure different settings for each motion detector.
- You can set specific actions and times for switching the lamps on and off in these apps, e.g. switch off one lamp after 2 minutes and another after 4 minutes.
