Me too. Ever since 58.x firmware came through, my V3 hub randomly went offline about every other week, LED turns red and it’s not responding altogether, needs a power cycle to recover. My first thought was it might be a hardware fault, so I purchased a brandnew V4 hub and migrated everything - and l…

Hi, @Peter-M Do you mean the Hub itself goes offline? In the case of @mlchelp , only devices went offline. So, I’d like to check first the details of your hub, to do so, can you open support access to your account, please? Confirm the email account registered in the forum is the same one you use …

Hi, thanks for replying. Yes, the whole hub goes offline, LED red, not responding on WLAN. Everything else on the same WLAN is perfectly fine in that situation, including smarthome devices. This has happened two or three times with the V3 hub, and now just last night the brandnew V4 replacement has …

[image] Peter-M: This has happened two or three times with the V3 hub, and now just last night the brandnew V4 replacement has done the same thing. Since both your V3 and the new V4 show the exact same dropout, it’s very unlikely to be the hub firmware - otherwise many more people would repor…

Hi, @Peter-M It’s worth checking if @Andreas_Roedl ’s suggestion improves the situation. I just checked your account, and I see that you have a few devices, and the memory status of your Hub is marked as “OK”. This means your issue is not related to any of those already reported. If you continue …

Hi, just real quick while I’m on a mobile device - I did request the hub logs earlier today, so far received none though. Will that be via email? My router logged the hub being unresponsive at 1:27am this morning; no further connection attempt until when I power cycled it 7:32am. Other WiFi devic…

[image] Peter-M: I did request the hub logs earlier today, so far received none though. Will that be via email? Those are uploaded to a server where only the engineering team has access. I’ll create a report to see if the engineering team can investigate if they can see something around that…

Hi, @Peter-M The engineering team mentioned that they saw logs about the Hub losing connection with the ISP, which would explain why you see offline/online events. However, the hub should recover and not remain offline and with the Red LED. The instructions I shared before are for when the hub is…

Hi nayelyz, thank you for your reply and analysis. I am in Germany, where private households are regularly disconnected and reconnected every 24 hrs. The in-house networks remain active during this brief moment. This happens for my DSL line in the early hours of the morning, and the SmartThings h…

Just a quick update to show I’m still watching - My V4 hub never again dropped offline ever since my last post, and it has now updated to firmware 59.8. I did not return my V3 for exchange under warranty, so if need be that one also is still available to try things out.

Hi, @Peter-M Thank you for the update. So, to investigate the issue with the V3 hub, you need to claim it again in your account and provide the hub logs after it goes offline as instructed here: [image] Hub dropping offline Devices & Integrations Hi, @Peter-M …

Noted. I’ll be extracting the WLAN log entries from my router just like I did last time - see my comment from Nov 20.
