Just to be sure: if this implies that all your sensors join for every transmission, then see [How often should a node do an OTAA Join, and is OTAA better than ABP?](https://www.thethingsnetwork.org/forum/t/how-often-should-a-node-do-an-otaa-join-and-is-otaa-better-than-abp/11192)

(And when creating a business around open source components, better be ready to understand [the code](https://github.com/TheThingsNetwork/lorawan-stack) and contribute to that…?)
