@gohan Yes it depends on the time lag or reaction time one can live with. I could live with 10-20 seconds for most of my things. And in this mode the node can stay for years on battery. Not actually tested but calculated ;)

Hi,

I am looking for a log to have the posibillity to look up error messages if something goes wrong in the gateway.

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.
