REST API

Setting a Layout

Layouts are set via JSON sent to /layout as HTTP POST requests. For example like this:

curl -X POST -T example_layout.json http://your.ip/layout

A layout consists of a single object with each key being the name of your choice for a status-tile. The value corresponding to that key is another object which has the x and y keys for the tiles location on the 3x2 grid, a desc key for an array with three strings (character set is CodePage437), each one line of the description, and optionally an icon key for a string corresponding to the name of an icon.

Setting states

States are set via JSON sent to /states as HTTP POST requests. For example like this:

{"solder":"unknown","power":"on","dishwasher":"off",
"shutters":"unknown","windows":"off","door":"on"}

For each tile that shall change state, a key-value pair has to be sent, the key being the name assigned in the layout, and the value being a string (either on for OK, off for bad, or anything else for unknown).

Other

• /text sets the status text at the bottom of the screen. (Send a string of up to 31 characters via HTTP POST.)
• /brightness sets the displays brightness. (Send a number from 0 to 100 via HTTP POST.)
• /power turns the Display on/off via DDC. (Send either on or off via HTTP POST.)
