I have measured the energy used by a garage door opener on more than one occasion. they draw a fair amount of power while operating, however. they don't draw power otherwise so the total energy is very low. I am wondering if a low cost non pure sine inverter to AC operated off the switches which would be low voltage would not serve the same low energy use and reliability of a DC garage door opener
