When installing new firmware in your Ecowitt “console” some Ecowitt devices upload the date in a different format.
If your dashboard blocks show “offline” please visit this discussion and install an updated . . .pwsWD / ecowitt / index.php script
Important: If you modified your ecowitt / index.php receiving script, f.i. for incomplete stations, there is only 1 instruction added
$arr['dateutc'] = urldecode ($arr['dateutc']); # 2023-09-01 thanks @olicat
