Streaming data directly to a file on my server, data from ESP8266 <--> MTU6050

Dear Community,

My plan is to keep a record of date in a file in which the movement of our house is recorded. For this I have an ESP8266wifi connected to a MTU6050 and this works partly. The below script shows a listing of the data on the serial monitor and that is it. Because I will be placing the modules on a beam in the top of our attic, I need the data to be streamed to my TrueNAS server or to an Odroid N2 that is always on.
I have seen examples using website php and html but I hope to find an easier way to catch this stream of data directly to my server in a file. I can than process the data with whatever I want later.

Below is the script that I found and can modify to add the steaming through wifi. Does anybody know of a project where this has already been done?

Moving house? Is it a camper or stationary building?

Heavy traffic on the road next to the house. Need a record :slight_smile:

Consider how easy it will be to loose the file if it is never closed on your server.
