I can confirm this as well I have the Weatherflow Tempest with the UDP driver as well as the cumulus realtime service. The station broadcast packet on a time base. This makes a few different packet types. Wind, Obs and Strikes as well as others. The only way to fix this is to bind the crt plugin to the archive packet instead of the loop. It will generate a full realtime.txt value without NULL values. The problem with this is that it's not really realtime for the wind. I might try myself at creating a service for a realtime tempest file. I have a few idea on how to do it. This is not a bad thing in itself because you get data values faster this way for the wind and realtime lightning strike events.
Packet I see are the following : rapid_wind, hub_status, obs_st, device_status, strike_evt Wind packet is emitted every 3 seconds Hub status packet every 10 seconds Observations every 60 seconds. Strikes are on event So one would need to build a realtime file with the first full observation write the realtime file, update the current observation with the wind value, write another file and when it receives the next observation update every other values. Looping light that would make a more realtime file. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
