3. Coffeepot fails to connect to the cloud service because it's in some remote place with no internet.

Why does the coffeepot / TV / thermostat need internet access? That's often undesirable for the user (because that means the whole things breaks if the originating company goes away). Not to mention, how would the user know which host to connect to? How would the device get on WiFi if there is no way to enter the password?

I know Chromecast does this by making you download a custom application (Google Home on a phone, or Chrome on a desktop); that's not always practical.

I do think SSL in as many places as possible is great; I just also think they're trying to push for too much before solving the problems it will cause first.

It doesn't need it. You can always just nmap your network, find its lan ip and connect straight through that over http. But that's not very user friendly, hence the dyndns.
