ESP-NOW provides bi-directional, point-to-point communication from one ESP32 device directly to another without the need for a central WiFi network. In a typical setup, a complete HomeSpan sketch runs "main" ESP32 device and connects to HomeKit by pairing with the Home App in the usual fashion. THen, one or more ike most commercial HomeKit devices, HomeSpan requires a power-consuming always-on WiFi connection, which unfortunately means powering a HomeKit device with batteries is generally not possible. For most applications, this is not a problem since your HomeSpan device will be controlling a real-world light, fan, thermostat, etc., and will likely be plugged into a wall outlet. However, there are some real-world applications where wall outlets are not readily available and battery-power is essential, such as remote temperature sensors, door and window sensors, or standalone switches.
