I experienced similar issues with Matter-based devices over the last couple of weeks. In particular, I noticed problems especially with Matter-over-WiFi devices from Shelly (Shelly 1 Gen4), but sometimes also with smart plugs from Eve.

The affected device is used to open my window blinds every morning, 30 minutes after sunrise. Therefore, I am unable to tell you an “exact” time when the device went offline.
