Error 500

Thanks for the update. I am glad that your hub is back online and connected to the cloud. I was able to download its error log. I would start by temporarily disabling your custom code apps and drivers to see if that resolves the problem. I have seen problems with the InfluxDB Logger as well as Wemo devices, so I would start with those.

If you don't know how to disable an app or a driver, please see "Disable Device Drivers" and "Disable Apps" sub-headings in the following documents:

Also noticed an issue with your location settings, so please make sure that all fields are populated under Settings >> Location and Modes.
