[Feature Request] Synchronisation only for known network connections

[gowima]

I run a DAWARICH server on my local network. I have configured a custom URL with auto sending marked as active. Datas are collected into a gpx and a csv file. When not at home the periodical update of collected measurement will fail. What is even worse, the data is more or less public since communication with DAWARICH is unsecured (http).

Would it be possible to confine the synchronisation to known networks. Maybe configured as a subtopic to the "auto sending" configuration?

Anyway, many kudos for your great work!
