hello to all I am trying or working with graphs but they are not visualized in the sitemap.
I have performed the following steps: -Install persistance rrd4j -create openhab / conf / persistance / rrd4j.persist
(I have searched the routes I’ve seen in several post but they are not in my configuration)
The content should look like this:
// for rrd charts, we need a cron strategy
everyMinute: “0 * * * *?”
default = everyChange
*: strategy = everyUpdate, everyMinute
The * is for persist ALL my item
-I have activated the persist in Paper UI
-I put the sitemaps line:
Chart item=Temperature period=h refresh=300
But don´t work, i read a lot of post and tutorals and nothing.
ok I will try your example, but how can I change the temperature manually? since it gets it from the weather underground addon.
And, even if the value does not change, should not a continuous line appear on the graph?
