@Fabien I tried yesterday but it doesn't seem to work. I will try again tonight as I did the test in a rush and may have overseen something.

I just thought about something, could it be possible that the RFM69 doesn't get enough power ? I will try with a separate power source tonight to rule out this.

Thx

@scalz I use 868 Mhz, I soldered antenna (82 mm), trust me there is no dumb question :)

I get what you say, it should work but I cannot figure out what is wrong

@maman Switching to NRF24 worked like a charm first time. node and gateway are communicating and everything is visible in Domoticz.

I will run range test tonight, if Range is ok I will keep the NRF24 as I am loosing the will to live with RFM69 (I'll still try again when I receive my new modules.)

Thanks
