Hi Peter,
It used to be necessary to restart each unit daily to check for updates, but checks for updates have (as you have noticed) been incorporated into the software for some time now and happen automatically (as long as stations are running software newer than 20191008). Older stations must do a manual update to a version newer than 20191008, after which updates will be fully automatic.
Is your query related to your comment in your other thread where you say that your station at Barrow doesn’t start properly after a timer restart? I did wonder that there was no feedback on that comment.
Regards
Peter
