The newer DIRIGERA hub has both radios, and recently added full thread support in a firmware update, so you should be good if you have it. Otherwise, add that or an upcoming hub or migrate the old bulbs.
I love my Ikea smart home gear, it works really well. Odd that a cheap furniture store that sells meatballs seems to have a more coherent smart device strategy than major tech companies!
I think that applies to many other electronics they sell too. I find them pretty well engineered overall.
My guess is that it’s because they sell any particular piece of hardware in millions and it’s in their best interest to design it properly so they don’t have to deal with the returns.
