As usual I’m pretty terrible at just buying devices and using them for their intended purpose, and in this case it has the irritating behaviour that if there’s a power cut and the battery runs out it doesn’t boot again when power returns, so here’s what I’ve learned so far.First, it’s clearly running Linux (nmap indicates that, as do the headers from the built-in webserver). The login page for the web interface has some text…
