This is usuall sufficient for most HomeSpan projects, but if // you have a LOT of Accessories (as per below) AND you are saving their states in NVS, you can // use up all the NVS space. If this occurs, HomeSpan will warn you of low NVS space upon boot-up. // The custom partition scheme included in this sketch folder solves this problem by eliminating // the SPIFFs partition (which is generally not used by HomeSpan) and using this portion of the flash // to provide an NVS space with 3906 records --- more than enough for even the largest projects. // For reference, in addition to HomeSpan's internal use of NVS (about 32 records), saving a // numerical Characteristic consumes one additional NVS record, and saving a string Characteristic (of // less than 32 characters) consumes two NVS records. Also, the ESP32 WiFi stack consumes about 130 // additional NVS records once initialized. As such, the sketch below requires: // 32 records (internal HomeSpan use) // + 320 records (80 Accessories * 4 saved numerical Characterstics) // + 160 records (80 Accessories * 2 records per saved string Characterstic) // + 130 records (with WiFi initialized) // ---------------------------------------- // = 642 NVS records needed (which exceeds the normal 504 limit, unless a custom partition scheme is used) // Note that once HomeSpan is paired with HomeKit, additional NVS records will be consumed to store the // pairing information for each verified HomeKit Controller. // Note also that when compiling under the Arduino IDE, the IDE reports the size of partition based on the // Partition Scheme you selected in the IDE menu, even though that scheme is not actually used if you have your // own "partition.csv" file, as in this example. This may lead the IDE to report an incorrect partition size. /////////////////////////////////////////////////////////////////////////////////////////// #include "HomeSpan.h" #define MAX_LIGHTS 80 // configure for 80 Light Accessories struct RGB_Light : Service::LightBulb { Characteristic::On power{0,true}; // save these 4 numerical Characteristics (4*80 = 320 NVS records) Characteristic::Hue H{0,true}; Characteristic::Saturation S{0,true}; Characteristic::Brightness V{0,true}; int lightNumber; RGB_Light(int n) : Service::LightBulb(){ lightNumber=n; LOG0("Configured RGB Light-%0d\n",lightNumber); } boolean update(){ if(power.updated()) LOG0("Light-%d: Power=%s",lightNumber,power.getNewVal()?"ON":"OFF"); if(H.updated()) LOG0("Light-%d: Hue=%d",lightNumber,H.getNewVal()); if(S.updated()) LOG0("Light-%d: Saturation=%d",lightNumber,S.getNewVal()); if(V.updated()) LOG0("Light-%d: Brightness=%d",lightNumber,V.getNewVal()); return(false); } }; void setup() { Serial.begin(115200); homeSpan.begin(Category::Lighting,"HomeSpan Max"); new SpanAccessory(); new Service::AccessoryInformation(); new Characteristic::Identify(); for(int i=1;i<=MAX_LIGHTS;i++){ char c[60]; sprintf(c,"Light-%02d",i); new SpanAccessory(); new Service::AccessoryInformation(); new Characteristic::Identify(); new Characteristic::Name(c,true); // save this string Characteristic (2*80 = 160 NVS records) new RGB_Light(i); } } ////////////////////////////////////// void loop(){ homeSpan.poll(); }
