Smartthings hub keeps going offline / disconnecting and connecting every minute of the day

Is anyone else experiencing this issue?

My smartthings hub keeps disconnecting and reconnecting hundreds of times each day. When I look at the events list (via api.smarttings.com) for my hub, it shows that it logs a hub status disconnected almost every minute of the day, and 10 to 30 seconds later its active again. Sometimes it stays disconnected for long (between 1 and 10 minutes) before going active again.

I have rebooted the hub, also tried taking the batteries out for 3 minutes whilst disconnecting the power and network cable with no luck (its worth mentioning that when I put the batteries back in, and plug the network cable and power back in, that it goes online for a minute or so, then disconnects again)

This is very frustrating - is anyone else experiencing this?

You should definitely contact ST support and let them investigate.

Go to the FB page and contact support there. I have had exactly the same issue before. It started on one day and then it has got resolved by itself or support did something. Anyhow you can reach out to them in FB for urgent cases.

Is your hub on wifi or cable? Try taking a hub to a different house / office and use the internet there to rule out connectivity issue with the wifi, cable or ISP. Also check that the router firewall is blocking any ports.

I am having the exact same issue. Did you find a solution?

I also have the same problem. Started 48hrs a go following an update. Interested to know if more are suffering from it, but it’s doing my swede in

I found the issue on my side: It was another device on my lan that took the same ip address (a raspberry pi). This caused both the to have the same ip address. The raspberry pi had a fixed ip, and you cannot fix the ip for the smartthings hub - and I could not force the smartthings hub to take another ip address, so i changed the ip for the raspberry pi.

This solved my issue in the end.

I thought the IP was assigned by the router? I tried connecting my hub directly to the wifi-extender but that didn’t seem to work either. I think you’re on to something (IP issues)

I found someone who posted this same thing in 2018. He said the issue was buildup on the cable at the pole. Here’s a link to the post: Solution! Random Smartthings hub disconnect and reconnects and Random Smartthings "Offline" notifications on phone app

I started having the same problem last night.

Another point to keep in mind, if it’s close to a USB 3.0 port or a cable connected to a USB 3.0 port, move it away since these ports cause RF interference.

It’s not, but that’s good to know. Thanks.

I have two STs and for some reason 1 of them keeps disconnecting and reconnects eventually…

Aforementioned, perhaps from USB 3.0 interference because the hub is within a couple feet from a computer? I will move it any see if that resolves the issue.

Edit:

I moved the hub and wired it to an (backhauled) Orbi Satellite and it has not disconnected since.

Mine is actually ATTACHED to an Orbi Satellite and having the same issue. Been connected for months and only started happening now.

I have not had a single issue since I wired with my backhauled (ethernet) satellite. Is your satellite backhauled or wireless?

I was having a similar issue recently after installing Circle (meetcirclecom), a parental control / internet filtering appliance, on my Orbi Wi-Fi 6 mesh network. My SmartThings hub would disconnect and reconnect for about 5 minutes every few hours. Ultimately, I set the SmartThings hub as an “unmanaged” device in Circle and so far, the disconnects have stopped. Will monitor my logs this week, but I’m optimistic.

This just started happening to mine today. It goes off for 5 or 10 minutes at a time, then comes back online. The led on the front stays solid green, however, and if it were offline it should be flashing blue. Rebooting didn’t fix the issue. It just came out of the blue, I haven’t made any changes to my wifi or my ST.

Does anyone know if connecting it with an ethernet cable to my router will turn off the wireless link? I’ve seen a lot of posts about how hard it is to switch the ST hub from ethernet to wifi… what about doing the opposite? Hardwiring might fix the issue… it’s worth a try if I don’t have to go through the whole setup process again…

there are some platform issues since yesterday…
