If anyone knows of compatible DIY-scale Hubitat items, please sing out.

1. 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.

2. 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.

DIY- Battery Backup Hubitat- under TEN bucks-NO soldering

EDIT 03/2022- There have been multiple reports of this same board being redesigned , such that there is now a momentary drop of power when switching from wall power to battery, rendering it useless as a UPS. My original boards are working fine 2+ years later, but that original board revision might not be obtainable. And like everything else, the price of lithium cells has skyrocketed(from 4-> ~9$) Essentially killing my initial sub 10 dollar solution. Using hubitat as my security system, I n…

for #2 I have no ideas

You could probably use one of these:

And have it trigger a zigbee/z-wave contact sensor or something similar. It would be a DIY project however.

I've got NUT running on a couple of boxes that have inexpensive UPS. They report all the stats you mention and more to MQTT and I wrote a very simple mqtt driver for Hubitat. I never look at the UPS stats myself. NUT was harder to do than the Hubitat driver.

You could use an ultrasonic sensor or laser distance sensor on hubduino if you want to do line-of-sight. Why is this topic in time out?

The topic was to vent my spleen, ergo home in Rome.
