When I spoke with tesla they said that the wire box which is attached to the wall does NOT need to be replaced. Remove the 4 screws holding the main unit to the box replace the main new unit and recommission. That's it.According to the manual, the temperature sensor is on the wall connector body (“main unit” in the manual), not on the wire box (the piece that attaches to the wall and has the terminals for the wires).
