- * 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.
