sendHeartbeat in binding?

[tomkxy]

What is required in MySensors nodes to make the send heartbeat option in the binding actually work. Do I need to explicitly include code in my node implementations? What happens if my nodes are sleeping?

Yes you need to add code - see here....

As to what happens if a node is sleeping, I have no idea, sorry.
