Discussion and questions about Cumulus weather station software version 1. This section and its subforums are the main place to get help with Cumulus. Anything which is not specific to the type of weather station goes in here; for anything specific to a type of weather station, please use the appropriate subforum. Use the 'website development' section for any questions relating to creating or running a web site for Cumulus data. Discussion of the stations themselves in these sections is fine.

Wind Vane display in Watson 8681 solar

Post by abarnett1934 » Sat 25 Apr 2015 5:39 pm

When I visit the web pages of other Cumulus users, I notice that their wind direction graph shows a great deal more information than mine does. (Melrosecrescentweather.co.uk) Look under the heading of Graphs and you will see that my wind direction graph is a very patchy. The average wind speed does not always show. Do you think a new weather vane would improve my display of my wind direction graph or do you think my display is normal?
Best wishes, Arthur

I've moved your post as I don't think it has anything to do with the SteelSeries gauges.

Firstly, Fine Offset vanes do tend to 'flap around' a lot. The average calculated by Cumulus solves this to a certain extent.

Secondly, it looks like you're not running Cumulus all the time. When running live, it plots an entry to the graph once a minute. When it starts up, it initialises the graphs from the log files. So the logger intervals that you have configured in Cumulus and in the logger have a bearing on how many points are plotted. It looks like you are using a long interval in one or both - 30 minutes, by the look of it.
