Rough numbers may a general guideline to CYA, but to your privacy and second point. What data is gathered, stored, for how long and shared with who? What are your options if the system goes offline?
I have a Nest Thermostat that I bought before Google acquired Nest, which raises another general issue of your device having an evolving T&C to use.

60 megabytes is a number that jumped out at me right away: It's about the upper bound of 1 packet per minute at the standard 1500 byte ethernet MTU.
That's about the right amount of data to do an HTTP POST home every minute with the basic temperature, humidity, what its internal IP address etc is.
Which seems completely reasonable to me. 5 megs is reasonable for your acks and occasional commands. I don't think there's anything suspicious about those numbers -- I'd probably have provided similar ones if I was designing this system.
1) Seems like a lot of data, what exactly is it communicating and to whom? What are the privacy policies?
2) What happens if/when the company stops running its servers? Does the device continue to work or will it become junk?
