Thanks for the tip about inserting the code, sorry! In this example I used two scratch specified and Light Sensor, in order to use the smoke sensor and light sensor in one gateway. Individually, these scratching are working properly and the WTO combine of together does not work, error appears. Thank you for understanding!
see here: sendSketchInfo("Light Sensor+GaS_Smoke_MQ2", "1.0");
* 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.
