Osram bulbs Connect directly to the smartthings hub, you cannot use the gateway with a SmartThings system. (It’s a pure zigbee coordinator, not a Wi-Fi/zigbee bridge like hue).

Zigbee bulbs Connected directly to the smartthings hub, including Osram, can mess up your zigbee mesh by losing messages which they are given to repeat.

FAQ: Are Smart Bulbs Repeaters? (Updated 2019: the new answer is yes, but may be inconsistent)

Hue Bridge Lightbulbs connected to a hue bridge are repeaters–but only for other devices attached to the same bridge. They essentially form their own mini network. So they won’t help with nearby sensors. Zwave bulbs Zwave lightbulbs like those from Linear and aeotec typically are repeaters – – but only for Z wave. These can actually be very useful in some specific use cases like getting zwave signal down basement stairs or across a garage. zigbee bulbs connected directly to the ST hub Zigbee lightbulbs like hue or Osram if connected directly to the SmartThings hub without using a bridge shift from the ZLL profile to the ZHA profile and then do typically act as repeaters for other ZHA devices. Or if they are Zigbee 3.0 devices, they will connect to the smartthing…

Note: SYLVANIA bulbs have a known firmware issue that can occasionally cause them to fail as ZigBee repeaters. This can potentially cause other ZigBee devices to fail to update and/or respond.
