The Things Uno Not Working with Low PowerSleep

I’m trying to make the node sleep for 5 minutes between sending data.

After some research i found you can use Rocket Scream Low-Power library to make it sleep, however when I try to use the include it says the board is not compatible.

However it clearly says it is compatible here: Low-Power - Arduino Reference

I have tried a few libraries and all say they are not compatible with the board, which is set to Leonardo since that is what the things uno is based on.

Any advice would be much appreciated.

What is “it” - if this is in text form, can you copy & paste it here so we can see the details.

For varying values of certitude:

“This library is compatible with the avr, samd architectures so you should be able to use it on the following Arduino boards”

Are you sleeping the Microchip RN module before asking the MCU to sleep?
