@magicw ok,thanks!

@hek For example，If i define MY_NODE_ID is 2,When the node reset,,the logic of this code will write the eeprom again(hwWriteConfig(EEPROM_NODE_ID_ADDRESS, MY_NODE_ID);). Isn't it?

if (MY_NODE_ID != AUTO) {
	// Set static id
       _nc.nodeId = MY_NODE_ID;
	// Save static id in eeprom
	hwWriteConfig(EEPROM_NODE_ID_ADDRESS, MY_NODE_ID);
}

In the stInitTransition function,if MY_NODE_ID is not AUTO,the code will write eeprom one time.if the node reset because some mistakes,It's to bad for the eeprom.Isn't it?

I have tested the lightsensor(2.0) 's Electric current（int 5v）about 6.5ma,if use 1500mAh 18650 Li battery，it can work about 10 days。How to increase the working hours? thanks!
