Hi, @rikki78! PRs are welcomed! How can i help you to finish "in-node" yourself?

Hi thanks for your reply
I've created two pull requests. To finish the in-node, all I need to know is on which event the state can be injected in the flows. I don't know where to start exactly. Perhaps you can point me in the right direction...

Hi @aborovsky
Could you give me some hints how to finish the node-in node?

edit: to be more exact, when will the node.receiveNotification be called?

@rikki78 Current node use marantz-avr as driver library.
According to it's sources there is not way to receive notifications automatically on some event happens: https://github.com/estbeetoo/marantz-avr/blob/master/lib/avreciever.js

I propose to implement polling logic:

1. Bind a listener after driver connected: fsm.on('connected', onConnected)
2. Inside of onConnected start poll interval: const statusPoll = setInterval(requestStatus, 1000)
3. inside of requestStatus(...) call const requestStatusPromise = fsm.connection.requestStatus(...);
4. connection.requestStatus(...) returns Promise, so do that: requestStatusPromise.then(status => node.receiveNotification(status))
5. also, don't forget to bind a listener on connection lost: fsm.on('disconnected', ()=> clearInterval(statusPoll))
