Sounds fishy, if the device allows this sort of fakery, that means the traffic is vulnerable to some sort of MITM attack by DNS poisoning/packet rerouting, which is somewhat disconcerting.

No. This is a thermostat at your home. It forwards its DNS requests to your router. Feel free to establish whatever security protocols you need there. Or, even better, host your own server.
