External sensor disconnect everybday same time

Has in the title I’ve an Eve Plus motion and lux sensor connected via matter over thread just outside my house. The mesh network is fairly strong in that location because i’ve a smart plug (that also act as a router) om the same wall but inside the house but still the sensor, everyday, around 16.00 to 17.00 became unavailable without any apparent reason. Someone else has noticed similar behaviour or has any idea how to debug it?

HA updated to latest HAOS release on a pi5 and ZBT-2 antenna. No zigbee or zwave networks. Also the socket doesn’t have any connection issue.

Thanks in advance
