After going through THRE Styrbar remotes, thinking they were all broken, we finally figured out what to do. Unfortunately the Styrbar directions do not mention hooking up to the Trådfri block first — I think, reading the reviews of the Styrbar remote, a LOT of people couldn’t figure this one out so here is my video explaining how to sync the Styrbar remote to Mittled lighting. I hope this can help someone and save some time.
