couldn't find official confirmation anywhere, but that looks like an arduino MKR WiFi 1010, which means it should have wifi for integration with home assistant or something. I realize that the overall process is probably too manual to fully automate, but you could at least turn it on and get the water heating in the morning, I imagine.
Although now that I look a little more, according to the quick start guide, wifi isn't yet enabled in the software, although I imagine that means they have plans to. Plus of course, with open source software, I guess it wouldn't be too hard to do yourself.
I like this thing! Would love to see James Hoffman review it
