Are you on the firmware beta? My hub has been much more stable since 44.7, with only one of these full hub crashes in the past two weeks.
I do still have my hub powered through a cheap Alexa-controlled plug. It’s been very convenient for power cycling away from home.
Yes, few times, no change.
No, i’m not on beta. But maybe I shluld be. 
I need to do this when I get back home later today.
Perhaps I spoke too soon. My hub is back at it this morning.
ST support is now directing me to this topic for any updates regarding the issue.
Here is the most recent update from support, Aug 12
This issue was escalated to the SmartThings Engineering team when and the team has been treating this as High Priority. Based on the most recent update the team believes to have isolated the problem and is actively testing to ensure the proper solution has been found before it is rolled out. please allow us some time to work on it. We will update you as soon as possible.
We apologize for the inconvenience this has caused. Please rest assured this issue has not been forgotten or sidelined. No additional troubleshooting is needed from the user at this time.
Meanwhile, your patience is highly appreciated.
Who did you bribe to get a decent support rep???
This is good news. I was away from home for six days and last three days hub was active/inactive. I had my alarm mode set on but what good it does if hub is in inactive state. Luckily I live in country where it is super safe and neighbors do look out for our place. Also water leak could have gone unnoticed due to this glitch. I’ve used ST for over year now and this is the biggest issue I’ve faced. Not a game changer yet but super annoying.
This has been the first issue that has had me considering jumping ship to home assistant, primarily due to the complete lack of communication from ST staff through both the support channel and here. My support ticket has been open for over two months now and the post from @Terri_Baker is the first update I’ve seen indicating that there’s progress on this.
I bought ST hub just before Edge beta stage was announced and all my devices are Edge compatible so I’ve dodged the bullet of migrating devices from Groovy to Edge which seems to be real problem for some of the older users. Therefore I haven’t seen any reason to jump the ship. But if I can’t rely on hub staying active more than few days in a row and getting message from my wife that house is not working then something has to be done.
I’m having problems. I’ve had my hub disconnect and reconnect about 5 times in the last 24 hours
Try rebooting the hub. I had the same problem a couple days ago and that seemed to work.
Also power cycling the hub works. Few minutes power off will do. Hipefully next firmware update will fix this.
I power cycled my hub last Thursday. Today I’ve got at least 6 notifications that my hub is offline/online. This good period lasted almost four days. This loop used to cause some of the devices to go offline and only deleting and re-pairing was the solution. Thankfully with the developer of these drivers we have managed to get things staying online after reboot/power cycle so I don’t lose some of my routines.
Is there any progress on this issue?
Have you identified the cause?
Is there anything that we as users can do to improve the stability of our hubs?
Support is now pointing to this community topic as the place where SmartThings staff are providing updates, though as yet there has been no update posted. Can you give us any information???
Hi @philh30, we believe that for most users the firmware release that went out this past week (44.9) should resolve the issue – we confirmed this in the beta populations (internal and external).
@posborne Thank you for responding. Do you have any advice if we continue to see this happening?
This is not the case. My hub cyles active/inactive multiple times per day.
Edit ticket #1372720
@philh30 @Terri_Baker I think escalating up through support and having them capture relevant data is the right next step. We’re confident that the incidence of the symptom across the fleet should be greatly reduced but it is a symptom that can come up in a number of scenarios. I didn’t mean to imply that this absolutely resolved all problems that may result in a similar symptom.
Is there any assistance you can provide to make that happen? I opened ticket 1367853 over two months ago, and never got past the “try rebooting your hub” level of support. Apparently that ticket was closed without notifying me, and now I have ticket 1396839. That’s two months of my hub going offline every day or two, getting nothing but canned responses from support, and no updates here. I’m not too enthusiastic about repeating that with a new ticket.
Can you provide any information on what those scenarios are? If I need to change something to have a more stable experience, I’m willing to do so. I don’t know where to begin troubleshooting though.
Last time I had to reboot or power cycle the hub was last Monday. I got the firmware update Tuesday. So far it looks like to be fixed.
