I changed to development version of Nodemanager this remove compilation errors and then found that recomended library from Sparkfun not work. Then i edited header file SensorSI7021.h to work with Adafruit library and it works
my SensorSI7021.h:
/*
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.
