Sure, there is already the KiCAD file including everything to play around with on your own; added a picture of the schematic here for a quick glance without downloading.
@DeepCore not wrong frequency no. But it looks like the feather doesn’t come with the antenna pre-soldered. Since the devices should be identical otherwise, the antenna could be what differs. But if it was, the rssi would probably have been different as well.
Does anybody have a link to a fixed version of this board? It's exactly what I am looking for form-wise, but I'd be nice if VCC was wired to 3.3v out of the box. Thanks!!
Hi @chey, no, with the pro minis and MySensors lib I couldn't get less.
Didn't measure with yet another multimeter though...
My battery sensors are working now for about a year and the battery levels are between 65% and 70%.
The sensor furthest from the gateway is at 65% and the 3 others at 70%.
Not bad I think.

Thank you both for your answers.
With so many parameters to play with, it was not easy to understand what was wrong.. But I think I finally got a way do get my hardware working
Here are my findings :
I thought I got RFM73 version of NRF24-like radios. They look like like here and here.
After checking and connecting all VCC and GND together, switch radios and arduinos... I got them suddenly working with Mysensors development librairies, then back to silence without apparent reason...
Indeed like @mark_venn suggested, I went back to stable librairies and try so set a static ID. Worked well... until it went back to silence again !
Then, following @mfalkvidd advice, I realised that flashing the eeprom_clear sketch solved my all my problems !
My summary :
Ensure that your 3.3V power supply is strong enough.
Ensure that your arduino, radios and sensors are sharing the same GND and VCC.
Use development librairies from github
Flash eeprom_clear before flashing your mysensor sketches
Then gatewaySerial and relayActuator should be able to communicate "out of box", mean you'll monitor some lines like this on the gateway serial : 0;255;3;0;9;read: 0-0-0 s=255,c=3,t=15,pt=0,l=2,sg=0:
Thanks again for your help, now I can start to play
@MiKa
Hi.
oki, in case i'll add some explanation.. I'll be busy for this week but you can simply use the serial gw example from MySensors for getting started, this should work. I didn't need to create a special board in arduino for this board, so if you're using it, you'll need to install&use the mattairtech SAMD21 board definition for the pin mapping.
