IKEA are one of the outliers in this space unfortunately.

Last year I bought some Osram Lightify bulbs, as here in Europe they are compatible with the Hue hub (which like Tradfri also works offline). I also got their own hub to update the bulbs, and it is absolutely useless. It says it is connected locally, but still it takes seconds for the bulbs to change state, and usually in a group only some of them change. The same bulbs paired with the Hue hub work perfectly.

It is WiFi only, and I‘ve had it randomly lose the connection and need to be reset. I haven’t tried it offline, but I imagine it’s not going to work.

I only got smart bulbs as I wanted to be able to change the colour temperature and brightness, they are just connected to dumb switches. Tradfri seems superior for this now, as their controllers don’t even need a hub to control lights.
