I have had trouble with Nest devices staying on an IP address after the lease expires, messing up the network once that address gets used by someone else. I had to reserve IPs for each one in the end. More than once, I have had a Nest smoke alarm go off for absolutely no reason, in an empty house. It's always nice to get an alert on your phone at work telling you your house is on fire. I don't think their QA department is the best.
