Apart from the fact that sensors have different transmitting intervals, usually - and I think that the WH24 array (boat) is not an exception here - an array sends its data in one set of data.
For the "random" intervals I suggest you study our FineOffset clone consoles etc. MUST READ thread thoroughly
https://www.wxforum.net/index.php?topic=40730.0By the way, your RTL-SDR may pick up all types of sensors from whatever origin - but that's a different story.
If you want to change the firmware of the WH2600 console/gateway/module, good luck with that. It's definitely not impossible, but you need to know what you are doing.
You probably have to reverse engineer the firmware (apart from copyright considerations) and then add your functionality ...
As this is an old and functionally limited device, there are no firmware updates from the manufacturer available anymore anyway.
But this forum is not the place for such undertakings - even though we may have capable members who could do this or have experimented with this.
If there are some and they feel inclined to reply to your post, you will notice.
But don't put too much hope into it.
If you want to verify if your assumptions regarding the behaviour of the WH2600 are correct, you can contact Fine Offset/Ecowitt (the manufacturer) and ask your question(s ).
On the other hand it is not clear to me what you mean by "pass to the server" ... Which server ??
Also, the terminology you are using is confusing. By definition a weather station consists of sensors and a console.
From there the sentence "It is not so that the weather station collects all data and sends it as one array of data" either makes no sense or is not correct.
It's the console which collects data from the sensors - and the construction type of the sensors (single, 2-in1, 3-in1, array ...) is irrelevant for this process.
Normally a fully functional WH2600 sends its data regularly - and to my knowledge it doesn't stop when one sensor observation is missing.
But my knowledge could be incomplete with these oldtimers ...
