I made a thread earlier about my trouble pairing Matter-compatible Essentials bulbs to my HA setup, but I was able to have that resolved.
However, a new issue: that bulb becomes unavailable after an hour or so of initial connection.
The bulb is connected via Thread to a Nanoleaf Lines border router, which then uses Matter-over-WiFi to communicate with my HAOS instance.
Curiously, restarting OTBR fixes this issue temporarily. I did some sleuthing online and found this suggestion, which appears to have worked. Ideas/thoughts?
I'm on the latest versions of OTBR, Matter server, HA Core, etc.
