As far as the Osram bulbs, the answer differs depending on whether you are in the US or the EU.
Zigbee has many different profiles for devices. Lightbulbs are typically either zigbee home automation (ZHA), which is also the profile that smart things uses; or zigbee light link, which is the profile that hue bulbs use when connected to a Hue bridge. (The bridge itself can talk to both ZLL devices and use your local area network to talk to nonZLL controllers like smart things, echo, and harmony. Hence the reason it is called a “bridge.” The bridge talks to the ZLL bulbs so the other controllers do not have to have the ZLL support.)
Osram, Weirdly, chose to use the ZHA for their bulbs sold in the US and ZLL for their bulbs sold in the EU. I believe they are the only manufacturer who did this. Consequently, their European model Bulbs can be connected to a Hue bridge, but their US model Bulbs cannot.
(hue did decide briefly back in December 2015 that they would only allow Hue-certified bulbs to be attached to the Hue bridge, but after a number of customers complained, they reversed that decision. So as long as you have the most current firmware, your Hue bridge will accept most bulbs that use the ZLL profile. So that lets the European Osram bulbs in, but leaves the US Osram bulbs out. )
There’s a thread in the forum where most of the people who have Osrams discuss issues with those devices. It’s a good place to ask questions about that brand.
