Hi servo. Below is my sketch that works in Home Assistant (DHT, reed, relay, motion sensors). It has only problem with multiple DHT but I'm working on it.
When connecting via USB use: #define MY_GATEWAY_SERIAL
// Enable debug prints to serial monitor

#endif
// Enable inclusion mode

// Enable Inclusion mode button on gateway
#define MY_INCLUSION_BUTTON_FEATURE
