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.
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.

Hi, not sure if @Floca get his nodes working, but for me, the problem got fixed with this
#define MY_RF69_IRQ_NUM MY_RF69_IRQ_PIN
as mentioned by @mfalkvidd Thanks!
I see a lot of "!TSF" and "NACK" which seems to be radio communication problems.
That's MySensors related and can be related to many things, from soldering problem to power / capacitor issues.
In MY_DEBUG mode you should see your temp/hum printed on serial every ~15s so there is something wrong there, either wiring or a code issue.
Ty with the example included with the library "i2c_SI7021.h", without any MySensors related stuff, to see if your sensor is detected. You should see temp/hum on the serial.
