Some systems already have that. Replaced a switch yesterday and re-arranged some things on my network board and got a HomeKit notification that some things were offline and when it came back. Knowing when something goes offline isn’t as useful as keeping things up though. With something like a hardwired camera/NVR, even if your ISP service is interrupted the cameras can still record, and you can put a UPS there to keep things going, even if the rest of the network is down.






For a regular personal loan it might be close. I can say over the last year my TFSA did a little better than the rate on my line of credit, but that’s just an anecdotal data point. Where it usually makes more sense is something like having a mortgage, which is generally a lower rate, making the minimum payments on a long amortization period and using any extra cash to invest. For a minimal risk investment like GICs and such the return is minimal. For a longer horizon, more volatile equity investments will do better, but also more risky for short term gains.
