Here is the sample code I am running, I have removed the AMG8833 libs and readings for the moment. At the start of the loop that line will print every cycle even when its in sleep mode. I would have thought that when it went in to sleep mode it would not print until the next wake cycle.
On the other example prior to using the LoRaWAN.Sleep(); and using the timer to wake up it seems to work.

const char myAppEui[] = { 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x** };
const char myAppKey[] = { 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x**, 0x** };

that’s with with updating TTN every minute.
