If your smart switches support it (Tuya/Lidl gateways doesn't, so there is still work to do), you can get some cashback when they momentarily turn some devices on or off to help offset imbalances on the power grid without relying on gas turbines.

Software is allowing governments to provide services online, 24/7, making driving to their overly large buildings a thing of the past.
