@donnib - I didn't continue this way but instead started using node-js based controller code that connects to a standard Ethernet gateway. @hek merged the code about two weeks ago. I will provide a tutorial on how to set it up from scratch shortly...
@OldSurferDude I've run into a similar issue where I was sending data from the controller to an actuator node with mutliple relays and having commands get dropped when sent in rapid succession.
I agree that an extra millisecond of wake time every 4 hours will make a negligible difference on total power draw and I'm OK adding a wait now that I know that I need to do it.
I agree that it might not make sense to build this support in to MySensors unless we find the optimized time with your method and then... I don't know... add a hacky/naive solution of having the RFM95W sleep implementation block before sending the sleep command,... I don't know the MySensors architecture whether that's even feasible without breaking some rules.
My secondary point of posting was definitely just to add to the knowledge base in this forum so someone else trying to put a Lora radio to sleep would find this and save some time.
@mfalkvidd No, the issue with sleep(0) still exists in V2.3.2. That is the version that the ArDuino Library installer installs currently . -- Work around is to call hwPowerDown(WDTO_SLEEP_FOEREVER) as in above code if you want the battery to last more than a day.
