Non-removable? It's so cute when they think they are in control. Potential work arounds:
Smuggled in Mexican thermostats.
Faraday cage around the thermostat.
Little tiny heater/cooler for the thermostat. Think of sticking an ice pack on your thermostat so that it always keeps the heater on.
Replacing the temperature sensor with one calibrated a little differently.
Alternate FM transmitter that tells your thermostat "everything's fine, keep running normally". Crank up the power and your neighbors will thank you.
Neutering the FM receiver.
Removing the thermostat entirely and just holding together the wires you need to either heat or cool your house.
I read the article to my hubby and these were pretty much the responses we came up with - before reading your post.
The stupid people will be at their mercy, though...
You left out the easiest of all - an FM jammer tuned to your thermostat’s receive frequency. A microwatt should be good enough to jam any transmission from Big Brother. Yet another way for Amazon.com to make money in the future. $5.00 plus shipping for a small FM transmitter that will run off of a watch battery for 10 years.
