Right. If you have to trust the device anyway, a blockchain only adds unnecessary complexity and signing the data will do.

Yes they could grab the sensors and throw them in another freezer but you can't solve every problem with one tool. At least they can't try to do anything to alter the history so it makes it harder. Much like I can enter a locked home, but the lock makes it harder. The alarm makes it harder again. But nothing is fool proof.
