@OpticFroggy sorry for the late reply. I haven't used rfm radios before, but tonight I finally got it working, with a lot of help from @scalz and the rest of the MySensors team.
This is my wiring:

These are my settings in the sketch:
#define MY_RADIO_RFM69
#define MY_RFM69_FREQUENCY RF69_433MHZ
#define MY_IS_RFM69HW
#define MY_RF69_IRQ_PIN D1
#define MY_RF69_IRQ_NUM MY_RF69_IRQ_PIN
#define MY_RF69_SPI_CS D2 // NSS
D8 cannot be used because it interferes with uploading sketches.
With this, I got an nodemcu rfm69H-433 ethernet gateway working, and a wemos d1 mini rfm69H-433 sensor node. I used MySensors 2.1.1.
