Hi davidi,
Given that your sensor is showing up on our map and the WunderMap, there’s no issue with your sensor’s connection. The “Checking status” banner is something that is known to not always work, and it’s near the top of our list to resolve in a future firmware update to ensure it works properly. It likely has to do with the fact that the “3RD” (third-party data processor) indicator isn’t working consistently now due to things changing, and the firmware hasn’t updated alongside them. Regardless of this, we can see that your sensor is connected. No need to worry about troubleshooting this status message.
Thank you for detailed troubleshooting and thought put into this. I’ve also updated our WiFi and Registration article to clarify that this case is a non-issue.
Our sensors don’t currently support IPv6. There is future hardware that we’re working on, but no guarantees at the moment.
Let us know if you have any additional concerns or need for clarification on this. Hoping that smoke clears up soon!
