I have added the C5 capacitor (on the "My Slim 2AA node"), and replaced the nrf24 from my GW with a NRF24L01+PA+LNA.

It's way better :)

So far, no problem .. I will keep you updated in the following days

Anyway, thanks for your help :dancer:

what about your nodes after several months ?

I finally have found the problem : I had only Vcc.h in my VCC folder ... So the .cpp file was misisng !!

--> noob alert :)

What type of sensors are they? Do they act like simple "switches" or what kind of signal do they offer on the output?

For the door, I assume they are like reed switch (with magnet fixed on the door itself)
For the movement ... I don't know !
