I don 't know if it helps but i tell you my story. I had all network using nrf24l01(7or8 nodes) and i had some lost data ,random,depend day time etc... So i change all radios to rfm69 and 69hw and never had a lost packet again. Happy end
Now i have an arduino pro mini 3.3v@ 8mhz connected to raspberry by serial (usb ftdi original) managed by domoticz. Rocksolid solution until now. Its there for months (6 maybe). One of the nodes its 50 m outside,on main gate. And same node controls lights,gate open,door bell and a fence perimeter alarm(fence cutted) .Never miss a notification.
This is my solution to not have issues with radios modules
