An inexpensive home-user UPS w/ NUT. Back in the '80's, IT closets had servers and related critical equipment behind uninterrupted power supply battery backup tied to network UPS tools. This old man is amazed he cannot find anything similar today to hang HE and my router on, sans bananas and raspberry Pi, forty years later. I'm not talking about a power out device, but a x-time count or percentage UPS battery life remaining interface.
An uniterrupted line-of-sight sensor like garage door openers have had for years. I would like to know if anything is specifically between or crosses between points A & B, not track from an array of motion sensors.
