How do I can I query the power in watts from a device via web browser ?

I use iRule (just started yesterday) for AV and Vera control (finally trying to replace SQ remote). I noticed that some of my devices used to display power in SQ remote, but they do not in iRule. I asked tech support, and his response was:

It is possible. When you send the command for status query in the web browser it returns and XML file. It is possible to create a feedback in the builder that parses out the values. If you send me the result of the query I can help you with the feedback.

I have no idea what he means. But if I get that i might even be able to expand that onto temperatures etc.

Does anybody understand what he means ? I need to query one of my appliance modules which has power feedback. But doing that in a web browser how would I get a xml file…

The HTTP query describe here [url=http://wiki.mios.com/index.php/Luup_Requests#live_energy_usage]Luup Requests - MiOS might be a very easy way to get the information you need. It returns tab delimited text, not XML, so should be easy to handle.

In fact, it returns the information for ALL devices using power.
