Every so often someone will come out with a mystery box that's supposed to do all sorts of magical things, but i've always been of the opinion there's a lot of smoke and mirrors going on.
AI has this to say about the Ting:
Limitations. What are the limitations of the Ting sensor?
AI Overview
Ting's main limitations are that it doesn't prevent all electrical fires (missing sudden failures, lightning, or some glowing connections), doesn't replace smoke detectors (only detects electrical issues, not other fire causes), requires power to function (no backup battery), and doesn't track energy use, focusing solely on voltage for hazard detection. It also relies on detecting developing faults over time, so it can't catch instantaneous problems like a short circuit that immediately trips a breaker
