My fineOffset weather station loses connection sometimes when lightening is
around.
I check this parameter.
rxCheckPercent 100.0
If it is not 100.0 then it has dropped off and then I have a normally
closed switch in the USB 5V line and I make the home automation turn it on
so the 5V drops and that resets the console.
It is in the weewx database as well.
I have the below in a bash script which I run via cron
RXCHECK=$(mysql --batch --column-names=0 -uweewx -pweewx --database=weewx
--execute="select rxCheckPercent from archive WHERE dateTime=(select
MAX(dateTime) from archive); ");
RXCHECK=`echo $RXCHECK | awk '{printf("%.1f", $1)}'`
echo $RXCHECK
I don't know if that helps you or not but it works in my case.
Cheers
