I guess everyone else is waiting for their RFM95 radios to arrive in the post from China?!?

I can confirm that MySensors 2.1 works on ProMini (W5100 MQTT Gateway & ProMini Node) using RFM95/LoRa.
I used the wiring and edited the W5100.h file (not sure i needed to, i tested RFM69 working first) as in this post in the forum - [SOLVED] W5100 Ethernet gateway with RFM69 Radio fails at init

The node didnt connect to the gateway at first but after adding capacitors, stating the RFM Frequency and reducing the transmit power to 2 (gateway and node were 1m apart), it came to life.
Just tested with door switch but all looks good.

Thanks MySesnors!!

Jonathan Caes - i used your amended #else code in W5100.h file, along with wiring/pinout from Frédéric Grandjean, and example Mysensors MQTTClientGateway sketch and got a ProMiniMQTTW5100Gateway working.
You are trying Ethernet gateway (not MQTT like me), but i think you may have a radio problem - i used 10uF and 1uF caps for the RFM69 radio and separate 3.3V supply (havent tried powering radio directly from ProMini VCC though.

The Ethernet and MQTT wiring is the same (according to main MySesnors instructions).

As far as protocols go, I choose the MQTT route because its simple and lightwieght, tipped to be a big player in IoT.

Im not a Mysensors expert, more of a hardware guy, but briefly looking at your diagram - i havent grounded the reset pin on the RFM69 like you have.
Try cutting that track so it floats
