It doesn’t list whether there is a 2nd endpoint. You up for resetting/re-pairing to get the live logs? If you paired it recently, you could check your hub’s events for the join info.
It would look like the screenshot in this post. You can see that this device had 2 endpoints and you can see the raw description for each. If we at least get the other endpoint number, we can code for it since I know what the clusters should be.
