It's not exactly the same, but in the UK, Economy 7 is effectively a low tech version of this. At night the price of electricity is cheaper, so electric storage heaters and boilers are switched on then to take advantage of the lower costs and reduce demand at peak times. Rather than using timers, it is controlled by a radio signal broadcast throughout the country. https://en.m.wikipedia.org/wiki/Economy_7 https://en.m.wikipedia.org/wiki/Economy_7
