AEP and class C lora nodes

Hi everybody,
I’ve bought an AEP and I’m integrating a class C smart plug.
Does anyone have noticed that AEP sometimes loses packet and have delays?

I’ve noticed that sometimes packets are received and treated suddenly, but sometimes with a nodered flow to do a very simple data processing it spends lot of time (5,6 seconds).

I don’t know if it’s due to class C actuator which not send data, to Nodered,
to Mosquitto or to Network server.

Can anyone help me?
Is there a view a log of routing activity (not including network server)?

Thanks
Michele
