Controlling the DEICE-Controller through the network is done by means of HTTP GET requests. Setting parameter values or querying readings or settings, all is done by requesting HTTP documents from the DEICE-Controller. The message to the DEICE-Controller thereby is coded into the URL as a CGI form parameter. The DEICE-Controller replies a one line document of the MIME type 'text/plain'.
The document name for remote control is /rmt , hence (assuming the DEICE-Controller is listening to the IP address 10.0.0.1), requesting a document with the URL
http://10.0.0.1/rmt?tmp0=?
will let the DEICE-Controller reply the actual level in a one line text document:
tmp0=36.3
This way all parameters may be queried or set, you may use your favorite web browser to try out the remote control of the DEICE-Controller manually.
