The upload-files used by the dashboard do not contain all history values we want to use.
Solution to this: run a cron-job which will save every 5 minutes the high-low values into a local file.
Explained and discussed here: => No High/Lows, where is history and graphs data used for, and ? cron ?
If you do not want to run a cron-job:
=> the two small scripts can be set to display todays high-lows only. Set line 4 in the scripts to comments.
Succes,
