Controlling openHAB with your voice - vpjuslin/openhab GitHub Wiki
This page should give an example how you can control openHAB via natural language without having to write code for every single item you want to control with your voice.
You need a working voice recognition system, that sends the recognized text to the VoiceCommand item in openHAB. The easiest way of doing is by using HABDroid, which works out of the box.
Other possible solutions are Tasker together with AutoVoice of Jasper (on Linux systems).
Your items should follow this naming convention:
<purpose>_<floorlevel>_<room>_<detail>
<purpose> = Shutter, Socket, Light, Temperature,...
<floorlevel> = GF, FF, SF,...
<room> = Bed, Living, Kitchen,...
<detail> = Door, Window, ...`
Additionaly there should be one "root"-group which contains all items that should be controllable by voice commands. In the given example this group is named "All"
And you need one String item named VoiceCommand
String VoiceCommand
This rules processes german voice commands and should be easily translatable to other languages. Basically the rule trys to read the state, the room (and the floorlevel of the room) and the purpose of the item to be changed. Based on this findings the item group "All" is searched for an item named "purpose_floorlevel_room_detail" which accepts the new state.
An additional feature in this rule is the possibility to give responses by TTS (currently only used when the temperature is changed in a room).
