Not yet, but maybe soon in California:
[T]he state of California looks to require that residents install remotely monitored temperature controls in their homes next year.
The government is seeking to limit rolling blackouts and free up electric and natural gas resources by mandating that every new heating and cooling system include a “non-removable” FM receiver. The thermostat is also capable of controlling other appliances in the house, such as electric water heaters, refrigerators, pool pumps, computers and lights in response to signals from utility companies. If contractors and residents refuse to comply with the mandate, their building permits will be denied.
The proposal, set to be considered by the [California Energy] commission Jan. 30, requires each thermostat to be equipped with a radio communication device to send “price signals” and automatically adjust temperature up or down 4 degrees for cooling and heating, as California’s public and private utility organizations deem necessary.
This might be the straw that forces the public to rise up in revolt. Some of the nastiest inter-office spats I’ve seen have been over thermostats.
