Data Types~

There are 5 major data types that openHASP uses when communicating over MQTT:

Boolean~

Properties with a boolean data type accept these values and are case insensitive:

  • true / ON / 1 / yes
  • false / OFF / 0 / no

The return value will be either 1/0 or on/off depending on the context.

Integer~

Numeric properties have integer values with a variable minimum and maximum input value.
Certain object properties also support negative values.

Details

int8 (signed) supports values ranging from -128 to 127.
uint8 (unsigned) supports values ranging from 0 to 255.
int16 (signed) supports values ranging from -32768 to 32767.
uint16 (unsigned) supports values ranging from 0 to 65535.

String~

Properties that accept textual input. When sending raw text in the MQTT payload or as command parameter no quotes are needed.
Only when a text value is included in a jsonl or json command, it needs to be quoted accoring to JSON rules.

JSON Object~

Some properties can be set or retrieved in JSON format too. The JSON object has several keys that have a boolean, integer or string data type.

Colors~

Color values can be:

  • Short names (from table below)
  • RGB hex code (#rrggbb)
  • Short hex code (#rgb)
  • RGB565 number format (0..65535)

Setting Color~

Examples: 

1
2
3
4
p0b2.value_color=13891
p1b5.text_color=silver
p2b3.bg_color=#C042A3
p2b4.border_color=#9f9

Return values~

When retrieving the color of an object, both the HTML representation as the RGB values are returned seperately.

The format will be a json object with components:

  • color : 6 digit hexadecimal code preceeded by a hash # sign.
  • r : byte value for red (0..255)
  • g : byte value for green (0..255)
  • b : byte value for blue (0..255)

For example, the color returned by a color picker change event is: 

1
{"color":"#00fff6","r":0,"g":255,"b":246}

Variables~

Some properties can be set with variable data at plate runtime. Use the strings below to retrieve data:

  • %ip% - IP address of the plate
  • %hostname% - hostname (nodename)
  • %ssid% - SSID of the network connected to
  • %model% - plate model (set in the firmware)
  • %version% - firmware version number
