I am new to TTN. I bought one gateway (Dragino LPS8) and connected it to TTN just a week ago.
Today, I have checked the traffic log and see that there is already a lot of traffic - but it all comes from 3 devices, belonging to the same app - and they come every 5 seconds (in a sequence, so each device sends every 15 seconds) and each has an airtime 1482.8 ms (and length of 23 bytes).
If I read this correctly, then each of this devices would have a duty cycle of 1482.8 / 15000 = 9.9% and airtime of 8540 s/day - which would be a clear breach of the European regulation and the TTN policy.
In addition, I guess it uses a big chunk of the gateways bandwidth.
My question is whether this is normal and if not, what can/should I do about it?
