Sorry for my delay as well, I’ve had a lot come up this week and haven’t been able to reply. Anyway, that’s what I was wondering. If you had said no, I was afraid my TV had a defective Hub. Seeing as you had your Thread Border Router go down as well, I think it is a firmware bug as well.
I didn’t want to take JDRoberts advice just yet as he said to Contact Samsung, which is why I hoped you would reply so I could see if it was a Samsung problem due to a defective hub or a SmartThings problem due to a possible bug in the Hub’s Firmware. Your reply would tell me exactly which support team to contact.
Like I said before you don’t see many on here discussing Samsung Devices, but now with almost all Samsung Devices requiring SmartThings for advanced functions (especially 2023 and newer products, which according to Samsung all are going to either have a hub included if they seem fit for it and/or have a SmartThings connected controller within the app) these devices are going to have to be fixed by contacting the SmartThings team not the Samsung’s Appliance team. So I think it helps to embrace the newcomers and try to help them out instead of leading them astray. Which I’ve seen a few topics ramp up quite frequently all created by newcomers wanting help and they are sent elsewhere as it’s just a Samsung Appliance, even though their problems seem to be due to a bug within the SmartThings Controller for that appliance.
Anyway, after I posted my last reply and saw JDRoberts post, I thought if I have to contact support I need to have proof of what is going on. At that moment my Thread Border Router was down/dead again for about the dozenth time in a week. Each time I would remove it and re-add it hoping to find the cause of why it kept going offline and becoming unavailable/not supported. Just a FYI, it would go offline anywhere from 5 minutes to 48 hours, but it would eventully die and never selfheal itself and I could never find a pattern. So, I took all the screenshots I could showing that Thread has died, but didn’t have proof of it ever being available to begin with. So, I deleted the hub and re-added it one more time so I could get screenshot proof of its availability and when it was to die again I was going to send in my report and dump the hub logs so that the Samsung/SmartThings would be able to look at them and hopefully see what was going on to hopefully find a fix.
TO MY SURPRISE THOUGH, up until the time you had replied it had been 5.5 days now and it never died once. It did not show up once, as I think my phone didn’t connect to the hub/server, but when I went back in and reloaded the controller it still showed up. The only other time it went down was when I rebooted my Wi-Fi Router and it went offline for a few minutes, but again when it came back online I still had Thread capabilities.
Sadly, right after I got your reply it finally died again and has died about another dozen times (both my Refrigerator Dongle and TV). But I did a hard reset of the TV by turning it on then holding the power button until I saw the OLED logo (You could try this with your TV and see if it comes back, give it about 2-5 minutes after you reboot your TV this way then check the SmartThings Web Interface and/or App) and restarting the Refridgerator by either flipping the physical switch or restarting it within the settings menu. After each reboot and reconnection to my Wi-Fi network they both selfhealed themselves.
I think I got some good news though. I was roaming the forums here and found out that others community members (highly known ones at least in my opinion) are have the same issue, but with the TV/Refrigerator Dongle. They are reporting having similar firmware “000.047.00011” or the previous one as what our hubs have as well. So I think it is a more widespread problem than we know. Anyway, I’m going to reply over there and let them know I also am having this issue. So you may want to as well. Hopefully the more reports we have the better chance it will get patched.
