If you have an electric light switch operated by infrared or microwave
detection of the presence of someone in the room, so that it goes on
automatically when you enter and goes off when you leave, without you
performing any action or uttering any sound, would allowing such an
action to take place be permissable?

If not, how are thermostatically-controlled furnaces or air-conditioners
treated? Do you have to shut them down before sundown Friday and
leave them off until the Sabbath has passed? What if you rent, and
have no control over the operation of the system except the thermostat
in your quarters? And what if you have no thermostat, and are at the
landlord's mercy in this case?
