yngve, thank you for a detailed problem description!
wu can be very unreliable about displaying data, so we should first ensure that weewx is getting correct data from the hardware. as you know, the wmr300 emits a pressure reading only every 900 seconds. so if you have an archive interval of 300 seconds, only every 3rd archive record will have a value for pressure. however, your archive interval of 900 seconds should address this. how often do you have records (REC not LOOP) with no pressure/altimeter/barometer? you can find out easily by doing a query on the weewx database: sqlite3 /var/lib/weewx.sdb select dateTime,pressure,barometer,altimeter from archive m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
