Except that the gospel of Mark specifically states that it wasn’t fig season. Why did Jesus even look for the figs when he should have known they were out of season. Why then curse the tree when it was just doing what fig trees are supposed to do? Guess Jesus can be an ass when he’s hangry.
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.
