Looks interesting.
According to This (unfortunately in Swedish) it uses Zigbee protocol.
I have seen some diskussions about Zigbee on the forum but no actual mysensor support.

Would this varistor work with 240v?

@den2k I have mine pro micro connected the same way, but i have a 3.3v regulator to the radio.
I don't know why but i guess i have experimented with both 5v and 3.3v so it came along when shifting the Arduino.

Sorry i cant help more but i honestly have no idea how to go forth.

@gregl the link doesn't work, here is the correct one:
https://community.openhab.org/
(only that annoying little s after http i think )

I'm using a pro Micro as serial gateway and sensor with the 'standard' pin configuration.
@den2k Do you have more than one Pro Micro and NRF24L01+ to try with?
Do you use the serial gateway sketch without modifications?
What do you get in the serial output when starting the gateway?

Good luck

You are changing in the wrong file.
The file you should change in is MyConfig.h.
