Correct. I wouldn’t necessarily hack it, but I’d be happy to physically disconnect antennas.

And I don’t carry my cell 24/7. I often go out and leave it at home when I’m not in a position to answer work calls anyway.

Or, when I have it, I often leave it in flight mode and check VM periodically — less distracting that way.

As far as a thermostat, I wonder if wiring the HVAC to a switch near the door would be as effective as a fancy-schmancy thermostat. Switch in the “ON” position causes the HVAC to do whatever the thermostat tells it to. When it’s “OFF”, it switches to a setting of 55F in cool mode or 85F in heat mode.

It would be no less intuitive than turning off the lights when you leave. And for multiple doors, you could have several momentary-contact switches working in parallel.
