We'd have to see your code to see what you are publishing. Your MQTT log looks very odd and likely needs some tweaking
MQTT: [{"dateTime":"1693128700.0","gpsLat":"52.152435"},{"dateTime":"1693128700.0","gpsLong":"9.929356"}] I'd expect something like {"dateTime":"1233456", "gpsLat":"52.1234", "gpsLong": "9.987"} for a more typical set of JSON to publish. You want one element (not in an array) with three items therein - dateTime/lat/lon. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
