I have a Samsung Soundbar HW B550 ZA and I’ve been trying to add it to my Smart Things app for several days now. But it’s not working. Smart Things keeps showing it as “Device Not Discovered “
You may have to add the soundbar manually. Sometimes when Smart Things is scanning for nearby devices, it doesn't pick them up due to interference that could be happening (like too many things are nearby and it's trying to pull them all up or the connection is super weak). You can check out the following link to see how to add to the Smart Things app: https://www.samsung.com/us/support/answer/ANS10002639/
If you are still having trouble with adding it to Smart Things, I'd recommend reaching out to them directly for further assistance. Their phone number is 866-813-2404 or you can check out their website: https://community.smartthings.com/
