Hey everyone! I’m new here, but I’ve been using Openhab for a couple of years now ^^ I’m writing this post because I’m at my wits and I’m not sure what else to try. Sorry for the long wall of text, but it’s a couple months of work here. Please let me know if I forgot to add anything important - I’ll update it! Long story short Openhab v2 used to find the TV (Samsung 55" model MU7005 ). For several reasons I reinstalled the binding a few times and the binding stopped picking up the TV. First, my setup: - Openhab v2.5.8 running on Docker; ( openhab/openhab:latest) - Ubuntu Server 18.04; (Is hardware relevant? It’s an i7 4770k with 16 gigs of ram, all on an samsung 120gig ssd 840) - TV connected via wi-fi (unifi AP); - Unifi Aps are connected to an Asus router (RT-68U); (If I’m missing anything please let me know!) Things I’ve tried, after reading a whole truckload of other threads, everywhere I could find them: - Reinstalled Binding several times; - Fully wiped the tele (everything. including the dongle thingiemajig.) - Checked the unifi controller, in case it was throwing a fit. Made sure upnp was on in both unifi controller and the router. - Manually added Thing through Paper UI with correct IP and Mac address; Thing stays as “Not Found”; - Manually added Thing through .thing file, same as above. - Checked Binding Logs: Error samsung TV “Interface set as None” - I couldn’t find anything about this one, any hints? - When I set the log into trace mode (with the thing added on the .thing file) I get constant information about the channels, but nothing about finding the TV… - Added all related ports (50000, upnp) to the ubuntu firewall clearance; - Turned off UFW on the server all together; - Turned off Pihole (I know… I’m getting desperate here!) - Deleted my docker image from the system and downloaded a new one; (I really don’t want to do this again… ☹ ) - Updated docker image from 2.5.4 to 2.5.8 just now - No change. I’ve exausted all my knowledge and I don’t know what else to try outside of a system reinstall, which I also would rather not do… Things I know: - It worked until dumb ass me decided to unsintall and reinstall the binding a whole bunch of times; - As soon as I installed Home Assistant (docker as well), it picks up the TV - this rules out any weirdness in my network, yes? At this point the only other test I could do is to pick up an old laptop and install openhab on it to check if it finds the god damned tv but… I already know OpenHab used to find it. That would just prove what I already know - I have a problem somewhere. Can anyone point me in another direction? Anything I may be missing? ---

Hi, Did you try to stop openhab and clean the cache ? The command is: **openhab-cli clean-cache** ---

I haven’t no. I assumed restarting a new image would mean the same, but I’ve just noticed that I never actually deleted the cache in the user folders… hmm. I’ll give it a whirl after work and report back. Thank you! ---

Hmm that command does not exist in my docker installation, nor does it work in karaf. By cleaning cache what folders do you mean the Tmp and cache folders? I found those in my user data files. Shut down open hab docker container, empty those two folders, restart container - is this correct? Edit: Update, no change. Deleted both the cache and the tmp folders located in the userdata folder. The locations of the files are different because it’s a docker container, but I couln’t find more openhab data anywhere else. I stopped the container and everything just to be sure. Any further hints?
