Hi all,

I’ve been playing around with a small MySensors network using [ NRF24L01 Modules. Everything works fine in open space, but once I put a couple of walls in between, the signal drops a lot.

I’m curious if anyone here has tried the PA/LNA versions — do they actually make a big difference in real-world use?

Also wondering about antennas:

Stick with the tiny PCB antenna, or is it really worth going external?

Any simple tweaks to cut down on packet loss when the environment is noisy?

Would love to hear what’s worked (or not worked) for you guys.
