Update stats-device-get.rst (#768)

alexmaurer-madis · web-flow · commit 07f22380354e · 2023-03-11T11:46:51.000+01:00
I added the key-value pair "lastConnectionDurationS".

The explanation of this value must be more precise (cumulative seconds ?) 
Is the counter set to zero on connection loss ?
Is it seconds ?
