thank you very much boots33 and mfalkvidd finaly wor also learn a lot on this example, its time now to try with relays i will add 2 relays that i can triger with switch or controler my working code for switch: /** 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.
