You still don't know the problem, but state, there is no such. I can think of one: 1-3W x 24h = 25 - 72Wh is quite another category of a problem to solve, without a grid backed power source, than 5-6 x 5 min x 1-3W = 0.42 - 1.5Wh would be. One LiFePO4 18650 battery holds about 6Wh, so the difference between "always on" and "turning on only when needed" is one vs. 24 such batteries for the same running time. Now that's what I call a use case. Still, without knowing the problem, my idea of a use case isn't any better in terms of a possible solution than stating, that there isn't even a problem to solve.
