receive() a message while in low power mode?

[strangeoptics]

Hi,

is it possible to receive messages while in some kind of low power mode?

I mean the controller is caching the request and the node is polling ever minute the controller for requests?

@strangeoptics No, currently the gateway (and as far as I know the controllers) do not buffer messages. If a node is sleeping, the message will be lost.

I haven't tried it out for myself yet, so i can not give you my experiences but there is a controller that can do what you want.
This is what the myHouse controller says:

Ah yes I forgott to describe my setup first. I use the MQTT-Gateway and OpenHAB 2. And I would like to stick with it as far as I can.

@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.
