Thanks for the feedback,
Would you want the whole sensor output available from the server manager?
I currently have a small CGI script that extracts the temperature - which I was thinking of posting as an example.
Making a panel for the information from one sensor would not be hard, but I don't know when I can start working on this.
I was also thinking of adding the possibility of emailing any 'alarms' that appear, but that is further in the distance - I have all the bits, but putting them together takes a little time.
It's just reached the end of Christmas Day so I'll have a think, but it may be a while before I have something good enough - maybe somebody else already has something suitable?
