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?

Wireshark will do it, although it takes bit more work to get it setup to
sniff wifi.

It is obviously working now, here is the graph it produces...
