I would like to have some guidence in my search on knowledge.
I am building a tech demo for my home, just to see if its possible to build wat i have in mind for some time.
In short, I would like to combine Weather information, comming home detection, XBMC and Philips Hue all togetter.
At this point i am trying to figure out how to:
- use variables in HTTP addresses and data
- a way to build an action based on a sensor or variabel.
Unfortunatly i still havent found the right information.
Any help would be great.
P.S. I am running OpenRemote on my Syno.
I can answer the part on Weather data, because that is what I use.
As source for my weatherdata I signed up for a free account at http://www.wunderground.com/weather/api/
At 5 minutes interval I download the local XML data to the subdirectory private that I made under webapps in the OpenRemote directory tree. As the free account allows only 500 API calls per day, and in OR I do need to make a call for every single value, this download was needed.
The data I read with a URL to the Synology directory a the following XPATH expression:
I did use XPATH round(concat(//response/current_observation/wind_gust_kph,"")) because I needed an integer value for further processing.
I did use the following URL's to retrieve the XML files
