I’m a little confused about how I can redirect the device settings to my local server???
HT-M7603 redirect to my own server
You mean you try to set your device as a gateway?
What I mean is, can I do the gateway and data decode process without using applications like chirpstack and direct the obtained data to my own server like http post? How healthy would this process be in terms of both data security and process practicality, or is it safer and easier to use just chirpstack directly?
No & Yes - you have a gateway already so it’s not really useful to add another lot of code on a working system - but then you can certainly take the data packets it sends and decode them.
If you are using ABP on the devices, it will be a few hundred lines of code, a few thousand if you wish to manage the devices using the MAC commands.
If you are using OTAA, it will be a few tens of thousands of code, more if you want MAC commands.
If you mess up, you may compromise data security. Practically speaking all the specifications are there and you have total control over your development environment.
Or you could download the free Chirpstack which runs on a Pi3 quite happily and do other things with the year or so of development & debugging you’d be facing.
Thank you for your suggestions, I will continue researching.
