Lua

Subscribing to Lua values allows the WebSocket to receive data sent by the push_to_web() Lua function from the controller API.

Subscribe Message

{
   "subscribe": "lua"
}

Change Message

For example, if a project needs to send a touch slider level to the WebSocket, it might have the following in a trigger Lua script:

level = getMySliderLevel() -- user-defined function to get the current slider level
push_to_web("slider_level", level) -- invoke callbacks on subscribers

And the data from the WebSocket might look like:

{
   "broadcast": "lua",
   "data": {
      "slider_level": 56
   }
}
