My router, which it connects to, only shows it in its list of attached
devices if I happen to log into my router at just the right instant. To
add to the problem of confirming it is working, the website is sometimes
just not available.

Is there any way I can confirm the gadget is actually working and
sending the data batches?

My router has an entry called "Syslog server" and I have
it pointed to a non-existent (at the moment) IP address.

192.168.5.100

Whatever the router is doing, gets logged there.

Then what you need, is a syslog thingy on the receiving end.
I don't remember what I used for that.
