New Homey Pro user here - also have a Samsung Q990D soundbar in place. So installed the Samsung SmartThings (Athom B.V.) app and it all seemed to integrate well. Took a couple of tries with the token, but all good. Built a simple flow for testing - when the Q-Series Soundbar Turned On, then Dim t…

Aaaand it’s not working again. Haven’t found out what causes it to lose sync or regain it. Power-cycling things doesn’t seem consistent

Well dang, now it’s not connected at all and doesn’t want to come back. The soundbar is seen just fine in the Android SmartThings app, but homey don’t like dat … So I try to repair … [image] [image] I log in, that works fine, then authorize [image] It says we can close the window, but on t…

We are aware of the issue! Thanks everybody for flagging Diagnostic reports are always welcome ofcourse

Hey. I have the same issue, my AC unit stopped reporting data overnight, probably after my Homey updated to v.12.9.1. Unfortunately, I didn’t think of checking the forum to see if other people had issues until after I had re-installed the app, generated a new token etc, but I can at least provide …

Looks like my Homey Pro updated to 12.9.1 yesterday at 6:55am, and Samsung Smarthings app updated to 3.6.2 today at 12:55pm. The soundbar is back :slight_smile: There still doesn’t seem to be two-way comms though - Homey doesn’t know when the soundbar has been turned on/off via the remote. And i…

Samsung broke something. I pushed a fix so at least your devices can be controlled again. But we’re not receiving realtime updates from SmartThings. We’ve asked them what’s happening, but so far, we didn’t get a reply.
