MySensors smartSleep support

[eric_smid]

Is it possible to implement MySensors smartSleep support?
The smartSleep function tells the controller a node is asleep and sends a heartbeat when awake again.
Supporting smartSleep, means messages that should be send to a sleeping node should be buffered. When the node sends a heartbeat, buffered messages should be send to the node.

Sleeping

To save battery it is crucial to sleep you node as much as possible. The node can wake up from external interrupts or by a timer.

Each sleep function has a "smart" variant, which sends heartbeat and process incoming messages before going to sleep. This is useful for sending out firmwares or commands for sleeping nodes. The controller must support buffering of messages and send them when node wakes up.

It would be great if this was implemented in Domotricz.

I too would be super keen for this feature to be implemented!

I could not find a good description how this should be implemented in the controller.
Something like before going to sleep, the node sends a I_HEARTBEAT ?
So all things send to a node, and that failed, we have to buffer ? Sure we need a limit for that
How to know that a node is using smartsleep ?

I had a chat with one of the MySensors devellopers.
Smartsleep is still under development, so it's probably wise to wait for a more stable implementation.
This will probably be in the 2.2.0 release, but no guarantees.

are there any more updates on this ?

Any news on this matter?

I really want to use this feature to reduce the power consumption of my nodes. Are there any news? Would be awesome!

Working on it...
