Ongoing issues with our Smartthings hubs

On Sunday, May 7th at 9:00 pm all our devices and our hubs showed clouds in our titles in our rooms in the Smartthings (ST) app with slashes through it. We rebooted our Smartthings main hub and the internet router. After the reboot, we went back to the Smartthings app, our tile in our rooms were now empty and the Smartthings hub was blinking red and green. On our Smartthings app it asked to setup a new network, as if I was starting from scratch. Three days were spent touching all our 74 devices. We factory default each item, because we could not delete them or exclude them because they were not there in the app. We did find out on Monday that there was a Smartthings upgrade being pushed to all Zigbee devices.

On May 10th all of our hubs showed solid red lights, we rebooted our hubs to make everything to start working again.

Once again, all our devices and our hubs showed clouds in our titles in our rooms in the Smartthings app with slashes through them. On Sunday, May 16th we excluded all but about six devices, those six devices we had to delete via the IDE. We also factory reset all nine of our Smartthings hubs. Then we created a new email account and a new Samsung account and started over again.

For two years all nine of our hubs showed excellent. Now they show poor, fair and excellent. We are not able to add any GE Z-Wave switches, First Alert smoke and carbon detectors, Aeotec range extenders, Smartthings plugs, IRIS Go Control garage door opener or our Eva logik outdoor smart plugs. All Amazon and SimpliSafe devices are working with no issues.

This evening, May 21st, all of hubs showed solid red lights, we rebooted our hubs to make everything to start working again. Smartthing cannot look up error logs to determine what is happening to our hubs, Smartthing suggested reaching out to Plume, Plume said, call Smartthings.

Any suggestions or help?
