If you are directly connecting hue lamps to the SmartThings hub without using a hue bridge that may be the cause of the other issues you are seeing, as your zigbee network may believe the Hue lamps will operate as zigbee repeaters but they may fail to pass along messages from other zigbee devices, such as your sensors, thus making the sensors look defective when it is really an issue with the lamps. This is why the direct connection is not recommended by either SmartThings or Philips.
FAQ: Do I need the Hue Bridge/Hub to Use a Hue Bulb with SmartThings?
The Ikea Tradfri smart bulbs tend to be a much more reliable alternative for direct connection.
If you do want to use the Hue bulbs with a direct connection with the new V3 app, you will probably need to use one of the stock zigbee DTHs. Hopefully someone who has done it will post with the specifics. But I did just want to mention the flawed repeater issue in case you were unaware of it.
