HomeKit Office — Color light + outlet + sensors via UDP

// HomeKit Office — Color light + outlet + sensors via UDP
// TinyC equivalent of the Scripter config:
//   >h 111-11-111
//   Licht,5,0,mh_pwr,mh_hue,mh_sat,mh_bri
//   Ecklicht,7,0,elamp
//   Bürotemperatur,10,0,btemp
//   BüroFeuchtigkeit,10,1,bhumi
//   BüroLuftdruck,10,2,bpress
//
// Sensors arrive via UDP multicast from a BME280 node.
// Light and outlet are controlled from Apple Home.
// All HomeKit globals are float — no x10 scaling needed.

// --- HomeKit-bound globals (native float values, auto-send via UDP) ---
global float mh_pwr;    // light on/off (0.0 or 1.0)
global float mh_hue;    // hue 0..360
global float mh_sat;    // saturation 0..100
global float mh_bri;    // brightness 0..100
global float elamp;     // corner light on/off (0.0 or 1.0)
global float btemp;     // temperature (e.g. 22.5)
global float bhumi;     // humidity (e.g. 55.0)
global float bpress;    // pressure (e.g. 1013.0)

// --- local state ---

// Value is already written to the global by the firmware before this is called.
