Electricians see quite a few failed hot connections on main service equipment, meter sockets and main breakers. Before they fail they typically run hot, hot enough to nearly burn your touching the panel door when it's closed looking for heating. I learned that early on, touch the panel door with it closed, first, to see if that runs hot. On occasion they do.
Usual trouble call is the customer's bill is 3 or 4 times normal.
I would guess that's I^2R loss without arcing mostly, 60 Hz sinewave and not something Ting would claim to detect. Usual call is high bill but not the lights blinking, with some bad neutral utility connections on occasion.
Utility would get the call and test it with their "beast of burden" and it would pass that. You would think they have a better quality engineered (solution, detection tool).
Back to square 1. If it was a onetime purchase standalone device for the $99., over a base of 1 million installs I am sure it would detect something. That would be 99 million in sales. If it does not function without the subscription fee or insurance promo deal, my opinion would be that the customer has to train the company to produce what they want, and to decline the spyware subscription service that is what they actually offer.
It is the customer's responsibility to train the market producers by declining the bad offers. it probably works on the same tech chips as arc fault breakers, meaning the chips inside are already mass produced at very low additional cost. It is at heart a very cheap device to put into production and to market. The cloud service is all expensive fluff. Possibly, because of the business model, the subscription fee, it may need that fluff to work.
That is the problem. It is at heart a good cheap device that could be useful over a large install base for detecting some problems that do happen. Over a sample of 1 million users it will see some problems. Using it as a backdoor way to sell a spyware subscription service is something to be denounced.
