Error is status of devices

At morning when there was no load shedding and no internet down was there we noticed that all the devices in the tinxy app were offline.

And approximately after 1 hour we found the tinxy app and all the devices were online( we were checking continuously in every 5 Minutes). In which there were 6 Nodes devices( 2 No.s) and one switch ( No. 2) from both devices got switched on automatically.

Also in 1 node same issue happened ( it got automatically on and off).but no issues were found in 2 nodes and 4 nodes.

This has happened for the first time after update to V7.
