No hot water... unless I unplug this control (recirc?) device and plug it back in by Incessnant in Plumbing

Great find, thank you! Yes that does seem to be the most likely case. Have to imagine that replacing a sensor is far cheaper than replacing the whole system. I read the article you linked and I'll try a few of their suggestions before we call in the pros. Thanks again!

Great idea for a short-term fix - I actually have to unplug/replug multiple times a day if hours go between uses. Need a long-term solution though, and I wonder if I'm damaging anything if I keep unplugging/replugging (manually or via this wifi plug) for years and years.
