The properties of secure IoT devices

In those situations, I could see it being an advantage to have the choice, ie. an option. Though if I can only go there in a few days time, with the freezer in particular, the safe option is anyway to assume the food is spoiled. When it is that hard to reach, knowing that it hasn't been hacked, is also potentially more difficult, and when more accessible, the extra warning offers less advantage, but the same danger.

Medical devices for home use nowadays often have an option to send data to a doctor, but that asks for a) a doctor that can safely handle, and deal with that, b) a secured connection. The latter condition usually is a not a given at all, and the first point is questionable. But, for now, and because of the sensitivity, it usually is an option that can be, but does not have to be, activated, and/or requires a separate action to make it happen.

My biggest problem with a lot of the IoT stuff is that the connection is not optional, or at least very hard to impossible to just not use (smart TV's and such are terrible, in a lot of ways, for example, even if they aren't hacked, they end up being an extra source of unasked for advertising), and the security is often questionable - being able to update would be a potential advantage, but without much control or influence by the owner that's not a great trade-off.
