Ok now I have found the proper place to include the missing .cpp files to generate the .o files. In the MySensor.h are all necessary .cpp files from the /core folder #if defined(MY_GATEWAY_LINUX) #include "drivers/Linux/EthernetClient.h" #include "drivers/Linux/EthernetServer.h" #include "drivers/Linux/IPAddress.h" #endif #include "drivers/PubSubClient/PubSubClient.cpp" #include "core/MyGatewayTransportMQTTClient.cpp" #include "core/MySmartSleep.cpp" #include "core/MySleepNode.cpp

Nice. Didn't know that. But still it would be a great feature for the gateway to give every one the feature of smartSleep despite the controller.

@Yveaux Yes you are right, didn't thought about the ack's. Another question. I would like to intercept the message flow in both directions in the gateway to put my logic in (smart sleep). Could you pinpoint me the method where this happens?

@strangeoptics when using MQTT you could publish the messages persistent and have the slave request them on wakeup. That would implement some form of message queuing.

Yes use sleep() ;) . Take a look at the api.

There is a topic in the forum, but it's just for ethernet gateway. If you subscribe to topic # you get all messages
