=== Rest interface ===<br />
The rest interface is at http://hottub/htmobile/rest/hottub. The requestor needs to use the correct http method for setting values (HTTP PUT)<br />
<br />
For getting REST values use HTTP GET<br />
curl http://hottub.home.hentschel.net/htmobile/rest/hottub/blower<br />
which gets <br />
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><blower state="ON"/><br />
<br />
To set the value, use HTTP PUT<br />
