MySensors Library & Examples  2.3.2-36-g2e00bf6

2  * The MySensors Arduino library handles the wireless radio link and protocol
3  * between your home built sensors/actuators and HA controller of choice.
4  * The sensors forms a self healing radio network with optional repeaters. Each
5  * repeater and gateway builds a routing tables in EEPROM which keeps track of the
6  * network topology allowing messages to be routed to nodes.
