1 year ago Don't run a cron job every five minutes. As you've discovered it won't work correctly as one run may still be synchronising to the station when the next run starts. There's a reason why the module is called pywws.hourly. If you need data more frequently then use "live" logging.
service.mqtt is a pywws.service.LiveDataService - it only ever sends the most recent data. If you want to send complete data to a database you need to use something else.
The WS1080 is set to log data every five minutes, the cron job does run every five minutes to collect data, due to known USB troubles jobs often fail, so next time there will be two records to collect, but mqtt only transmits only one record instead. Only the last record seems to be sent. I think the cause is the missing time stamp fields in mqtt, but those could be added so all records are properly forwarded via mosquitto mqtt to telegraf and finally to influxdb?
