So the highest risk device on my RF network is my thermostat. But not only do I get alerts for out of range conditions, the beauty of the local attacker model is most types of attacks become silly: The thermostat has a predefined range of relatively normal temperatures, so the only way to really cause damage is turning it off. You could bring a custom-programmed RF transceiver and plant it on my property for the job, or you could use a $5 wrench to shut off my natural gas and pull the power shutoff on my AC condenser. I think the latter is infinitely more likely.
